RR Racing is proud to make history again by being the first to offer an ECU reprogramming for Lexus RC F engine control unit (ECU). The Lexus RC F ECU is a very complex and sophisticated engine management system. RR Racing has been developing this upgrade tune with weeks of testing, intimately understanding RC F ECU's parameters and structures, testing various changes to optimize power and torque effectively while retaining stock fuel efficiency, knock control sensitivity, and other built in safety features. During the development and testing period, we have logged many track hours and hundreds of miles of road testing and road-dyno logging with many more hours spent on a sophisticated Dynojet dyno at a top-notch climate controlled facility.
We had done most of our development on the road, under real world conditions, doing hundreds of runs, datalogs, and hundreds of miles of testing between re-maps in order to determine how the ECU reacts to changes and adjust learning parameters. We have developed a full understanding of the following ECU functions/parameters, including but not limited to:
Direct Injection / Port Injection fuel mapping
Ignition control (RC F has base ignition maps, cam timing dependent ignition maps, knock correction maps)
Intake and Exhaust variable cam maps
Torque to throttle mapping (allows us to enhance throttle response)
CEL parameters (e.g., disabling of O2 sensor warning light for off road cars equipped with headers)
Our on road impressions are that the RC F pulls much more smoothly and linearly, with excellent midrange torque improvement you can definitely feel and appreciate.
After extensive road dyno and datalogs, we headed over to top-notch climate controlled Dynojet testing facility and conducted many hours of dyno tests.

Other FAQs:
Do you recommend aftermarket intakes?
We do not recommend any aftermarket intakes that remove the factory airbox. The only recommended intakes are intakes pipes like our RR-Racing Intake pipe, or equivalent.
What about that Supercharger Kit you guys are working on?
We released a supercharger kit for the Lexus RCF in February 2017. When you buy this tune, you will get $300 credit when you ready purchase the supercharger kit.
This package includes two of the best quality products on market for Lexus 3XX --
PPE headers and Ark Grip exhaust with burnt tips (please note that you can chose polished tips as an option to this product). These products combined with our special tune deliver the most power available for the 3XX platform anywhere at an incredible package price! We estimate consistent gains of 38 to 48 whp (65 to 75 whp for IS300) with this package!
Please note that you can also buy tune and headers by selecting the headers option when buying the tune product. Also you can buy an exhaust with the 3XX tune (please select the tune as an option with one of the exhaust products we offer).
The tune that comes with this product is for the following models with 2GR-FSE 3.5L v6 engine: IS350, IS300 AWD 2014 and newer (3rd generation) models.
RR Racing is proud to release yet another great value performance package for the Lexus! The Lexus 300/350 ECU is a very complex and sophisticated engine management system. As always, we have worked very hard over a course of many months on developing this tune using our IS350 F Sport shop car as well as our customers' cars. We developed both on the dyno AND on the road. We have thoroughly tested various changes in order to optimize power and torque effectively while retaining stock fuel efficiency, knock control sensitivity, and other built in safety features.
We especially excited to report the results of our IS300 tune. Now IS/RC300 owners can have all the power of an IS/RC350 at a fraction of the cost, by simply recalibrating the ECU!
So as you can see this was not a weekend project for us, where we slapped a Lexus on the dyno, played around a bit for a day or weekend, and and now we are selling a tune. We had done most of our development on the road, under real world conditions, doing hundreds of runs, datalogs, and hundreds of miles of testing between re-maps in order to determine how the ECU reacts to changes and adjust learning parameters. In addition we use our sophisticated in-house AWD DynoJet 424x LINX to fine tune our calibrations. Our ECU tune enhances the following ECU functions/parameters, including but not limited to:
Direct Injection / Port Injection fuel mapping
Ignition control (300/350 has base ignition maps, cam timing dependent ignition maps, knock correction maps)
Variable cam maps
Torque to throttle mapping (allows us to enhance throttle response)
Optional rev limit increase to 7200 RPM (helps the power curve)
We raised the shift points to higher rev limits in Sport and Sport+ modes (rev limit can only be reached in manual shifting with traction control off)
Optional speed limit elimination
CEL parameters
Our on road impressions are that the 300/350 pulls much more smoothly and linearly, with excellent midrange and top-end improvement. One of the most effective changes to the 300/350 is increasing the rev limit to 7200rpm (we can further increase engine rev limit to 7400rpm upon request, but we feel that it may impact long term reliability). As you can see from the dyno results below, the 2GR-FSE v6 continues to pull all the way to the revised 7200 rpm rev limit. This results in significantly more "area under the curve" and better acceleration times.
All of our extensive dyno testing is conducted in our testing and development facility on a top-notch brand new Dynojet 424x all wheel drive Dyno equipment.
Our tune results are summarized in the following table with supporting dyno graphs below.
Ordering Procedure
Please select this product and chose all required options as follows:

Other FAQs:
Why do you provide a range of “tuned gains,” not a precise value?
There are many factors that influence dyno results and lead to variability in power measurement. Additionally, your ECU is constantly making changes based on sensor feedback that significantly influence engine output – and this is the case even on a stock ECU. So bottom line is that regardless of the mod you install, actual gains will vary. We make every effort to provide actual, factual, and transparent dyno data for our customers.
Do you recommend aftermarket intakes? At this time, we do not recommend any aftermarket intakes that remove the factory airbox.
Can you work with me or my tuner to improve my tune?
In most cases yes. If you plan on taking your car to the dyno, please contact us ahead of time in order to discuss the type of datalog data we need in order to fine tune your ECU, should it be required. In most cases, custom tune fees will range from $200-$300.
What about that Supercharger Kit you guys are working on?
We may release a supercharger kit for the Lexus IS350 in first quarter 2017. At this time, and until further notice, we are offering all of our customers who purchase the tune now partial credit (the amount to be determined based on SC kit pricing) towards the supercharger system through the spring/summer, should they choose to upgrade during that time.
Another exciting product from RR Racing! After nearly 12 years since the introduction of the 2nd generation Lexus IS350 Lexus enthusiasts FINALLY have an option that makes some serious power. The 2IS Supercharger kit features the same supercharger and drive system proven with over 15,000 miles of track, dyno, and street testing on our shop 2014 IS350. We have now taken our 3IS system and adapted it to the 2IS. Our goal for our Stage I kit was to exceed the power to weight ratio of the top-of-the range Lexus IS-F and RC-F, while creating reliable, smooth and seamless levels of power that elevate the IS300/350 into a completely different league of performance. With this Stage 2 release for the 2nd gen IS, we are well exceeding this goal!
Please note, dyno results are for IS350 RWD equipped with headers and Invidia exhaust. This exhaust utilizes a single 70mm pipe which is somewhat restrictive at these hp levels (we recommend a “true dual” system for additional gains).
RR470 Stage I Kit Specifications:
Power: For the base "Stage I" kit, our customers can expect to make about 412 whp (wheel horsepower on a Dynojet dyno, SAE correction) at approximately 6.5psi peak boost pressure, 93 pump gas, equipped with standard PPE headers and a standard 2.5” dual exhaust. Please also refer to the Dyno chart below for the RWD model.
Tuned ECU: We have logged countless development hours perfecting our ECU tune for the IS350 for ultimate reliability and drivability.
Supplementary External Fuel computer: User tunable fuel control can be adjusted in real time. In the future this computer even allows us the option to increase injector size, and add true flex fuel control for e85 applications, something that is currently under development.
Supercharger:Rotrex Supercharger, c38-92 (largest Rotrex SC). Rotrex SC's are extremely efficient and quiet due to their planetary drive system which spins up to 90,000 rpm, much like a turbocharger. The c38-91 will support up to 500+whp, depending on future staged upgrades we offer. No need to every upgrade your SC to make more power!
Dry Sump SC Oiling system with Oil Cooler: Our system comes with an autonomous dry sump oiling system and oil cooler, so our system does not require plumbing oil lines to the engine, or adding any additional heat input to the engine’s cooling system.
Dedicated Drive System: Our system comes with an autonomous dry sump oiling system and oil cooler, so our system does not require plumbing oil lines to the engine, or adding any additional heat input to the engine’s cooling system. Rather than using the accessory belt to drive the SC, we designed a dedicated drive system that allows us to achieve the necessary belt tension for a reliable SC drive, without overstressing the alternator, water pump, and AC bearings.
Automatic Tensioner System: No need to constantly adjust or tighten the SC belt, our automatic tensioner will maintain proper tension for the life of the belt.
High Quality Turbosmart "Big Bubba" Billet Blow Off Valve: Adequate venting is essential for SC responsiveness, reliability, and drivability, so rather than use a cheap plastic or miniature BOV, we went the extra mile and use a premium BOV.
Custom Air/Air Intercooler: We use a large intercooler core, and manufacture our intercoolers in-house. These intercoolers are extremely high quality, and are capable of supporting up to 500+whp, so there is no need to ever upgrade!
Quality and Warranty:As all our other products, this kit enjoys our well known stringent quality standards for product development, manufacturing and service backed by 2-3 years Rotrex Warranty on SC, plus 1 year warranty on all other components supplied with your kit.

Please note that with all our testing, the OBD flashing of Lexus's ECU is new. If you encounter problems during or after flashing, you may need to send us your ECU for re-flashing using our equipment.
RR Racing is proud to make history by being able to offer an OBD device tune for Lexus IS-F engine control unit (ECU) based on our famous ECU upgrade product!
Please note that we now offer the ECU tune in combination with our Tuned Intake and as part of the Performance Upgrade product
The Lexus IS-F ECU is a very complex and sophisticated engine management system. RR Racing has been developing this upgrade tune for many months, intimately understanding IS-F ECU's parameters and structures, testing various changes to optimize power and torque effectively while retaining stock fuel efficiency, knock control sensitivity, and other built in safety features. During the development and testing period, we have logged many track hours and over 2,000 miles of road testing and road-dyno logging with many more hours spent on a sophisticated Dynojet dyno at a top-notch climate controlled facility. Then we tested various OBD units, and only when we were convinced that the device is reliable, we released it as a product.
So as you can see this was not a weekend project for us, where we slapped on IS-F on the dyno, played around a bit for a day or weekend, and and now we are selling a tune. We had done most of our development on the road, under real world conditions, doing hundreds of runs, datalogs, and hundreds of miles of testing between re-maps in order to determine how the ECU reacts to changes and adjust learning parameters. We have developed a full understanding of the following ECU functions/parameters, including but not limited to:

Intake and Exhaust variable cam maps
Torque to throttle mapping (allows us to enhance throttle response)
Optional rev limit increases -- 7200 (7400 RPM not recommended without our TCU tune)
CEL parameters (e.g., disabling of O2 sensor warning light)
Our on road impressions are that the IS-F pulls much more smoothly and linearly, with excellent midrange and top-end improvement. This was evidenced in our ignition curve datalogs shown below where a combination of ignition and cam timing adjustments resulted in a much more linear and aggressive ignition curve, free of any detonation or large ignition corrections:
After extensive road dyno and datalogs, we headed over to top-notch climate controlled Dynojet testing facility and conducted many hours of dyno tests.
Please refer to our image gallery for dyno results comparisons. The chart below summarizes some of the gains for typical starting modifications.

Please note that PPE headers and our Carbon Intake are now available as an option with this product at a discounted price!
We are happy that finally we found a reliable OBD tuning device solution for our Lexus IS/GS350 (2gen) engine control unit (ECU) upgrade tune! Now our 2nd gen customers do not have to send their ECU for upgrade anymore.
The Lexus 350 is a very complex and sophisticated engine management system. We have worked hard on developing this tune, both on the dyno AND testing extensively on the road. We have thoroughly tested various changes in order to optimize power and torque effectively while retaining stock fuel efficiency, knock control sensitivity, and other built in safety features.

CEL parameters
Our on road impressions are that the 350 pulls much more smoothly and linearly, with excellent midrange and top-end improvement. One of the most effective changes to the 350 is increasing the rev limit to 7000 or even 7200 (later may have more impact on engine life). As you can see from the dyno results below, the 350 continues to pull all the way to the revised 7000 rpm rev limit (7200 Dyno is not available at this time). This results in significantly more "area under the curve" and better acceleration times.
We estimate between 10 to 15 whp and wtq gains with this tune.

Please note that our ECU Upgrade Tune is available as an option with this product at a reduced price (not for 2017 model years). Tune price includes ECU return overnight shipping.
The PPE RCF/GSF Headers make a significant increase in flow compared to the stock manifolds. Tube lengths and diameters are increased coming together into a ported 4-1 parallel merge collector. Completely TIG welded construction with thick 16 gauge tubing for long lasting power gains.
According to our estimates PPE headers can make between 25 to 35 (40 to 48 with our tune)additional wheel horsepower .
Please note that the headers do not come with manifold gaskets. For older cars replacing manifold gaskets may be necessary. We offer these as one of the options with this product. These headers do not require a re-location bracket.
Header Features:
Comes with optional RR Racing ECU Upgrade Tune package for increase power gain and O2 sensor CEL elimination
3/8" thick head and outlet flanges
Mandrel bent Stainless Steel 16 gauge tubing
15 degree parallel merge collectors
Runners are welded with Silicabronze at the head flange
Porting at flanges
Flat sanded head flanges
Includes factory style outlet gaskets and optional engine gaskets
Includes electronic O2 simulator (when bought without ECU upgrade package)

We are proud to introduce the ultimate normally aspirated performance package for Lexus IS-F! This package includes our new Tuned Intake System, our PPE Header, all combined with our famous ECU upgrade tune using an OBD device. This represents an increase of
60 to 80 wheel hp and 50 to 60 in wheel torque over stock (with a high flow exhaust)!
RR Racing Tuned Intake System
Throughout our rigorous testing program, we discovered that the OEM airbox intake is adequate up to about 410 whp, but beyond that level, it becomes restrictive. Tuned header equipped cars seemed to max out at around 410-415 whp. So it turns out that once you add headers and improve exhaust flow, the intake becomes restrictive! Our ability to tune the IS-F’s ECU has allowed us to develop the ultimate intake system by recalibrating the airflow curve to allow the use of a much larger MAF (mass airflow) housing.
RR-Racing Tuned Intake Features:
Additional power gains of 10 to 15 whp over an ISF equipped with our ECU upgrade, headers, and a high flow exhaust!
The MAF tube diameter is significantly increased from 80mm to 87mm. Upgrading the MAF housing is only possible through extensive recalibration of the ECU.
To take advantage of the added flow of the 87mm MAF housing, we utilize a large genuine K&N cone filter with 7” composite velocity stack.
True “cold air” design is fully heat shielded and intake box coated with genuine DEI Reflect-a-gold coating.
Genuine carbon fiber lid is easy to open in order to clean and inspect the filter element.
RR-Racing Tuned intake is compatible with most aftermarket intake elbows (but we recommend the shown RR Racing Titanium Intake elbow offered as an option!).
RR-Racing tuned intake requires a special ECU calibration. RR Racing ECU Upgrade Tune is included with this product.
Please note: If you already bought our tune, you must have your ECU recalibrated in order to use this intake -- please select the "Recalibrate" option, and you will be given credit for the tune portion of the price.
Please note: To provide the maximum power, this intake system must be installed with headers and a high flow exhaust. If you do not have after market headers, then please consider our Power Package product that includes this system combined with our PPE headers at a reduced package price.
The charts below shows the gains of our Tuned Intake system.
RR Racing PPE Headers
RR Racing has been evaluating headers for Lexus IS-F for some time now. When finally choosing the headers to complement our ECU upgrade and supercharger for Lexus IS-F, we selected the best headers available on the market. The PPE ISF Headers make a significant increase in flow compared to the stock manifolds. Tube lengths and diameters are increased coming together into a ported 4-1 parallel merge collector. Completely TIG welded construction with thick 16 gauge tubing for long lasting power gains.
According to our estimates PPE headers can make between 6-12 additional wheel horsepower compared to OEM manifolds with removed catalysts. If you buy headers with the tune package, then you can expect total power gains (including an exhaust) of 60-70hp over stock! Please refer to our ECU upgrade tune product for recent estimates.
The headers include new Lexus 60mm outlet gaskets and a dipstick relocation bracket. A modified factory dipstick tube is supplied. If you do not chose the ECU upgrade option package, then we will provide the RR Racing O2 simulator at no additional charge.
Please note that the headers do not come with manifold gaskets. For older cars replacing manifold gaskets may be necessary. We offer these as one of the options with this product.
Header Features:
Comes with optional RR Racing ECU Upgrade Tune package for increase power gain
3/8" thick head and outlet flanges
Mandrel bent Stainless Steel 16 gauge tubing
15 degree parallel merge collectors
Runners are welded with Silicabronze at the head flange
Porting at flanges
Flat sanded head flanges
Includes factory style outlet gaskets and optional engine gaskets
Includes a modified factory dipstick tube and bracket

Other FAQs:
Why do you provide a range of “tuned gains,” not a precise value?
There are many factors that influence dyno results and lead to variability in power measurement. Additionally, your ECU is constantly making changes based on sensor feedback that significantly influence engine output – and this is the case even on a stock ECU. So bottom line is that regardless of the mod you install, actual gains will vary. We make every effort to provide actual, factual, and transparent dyno data for our customers.
Do you recommend aftermarket intakes?
We do not recommend any aftermarket intakes that remove the factory airbox. The only recommended intakes are intakes pipes like our RR-Racing Intake pipe, or equivalent.
Can you work with me or my tuner to improve my tune?
In most cases yes. If you plan on taking your car to the dyno, please contact us ahead of time in order to discuss the type of datalog data we need in order to fine tune your ECU, should it be required. In most cases, custom tune fees will range from $200-$300.
What about that Supercharger Kit you guys are working on?
We expect to release a supercharger kit for the Lexus ISF in Spring 2016. At this time, and until further notice, we are offering all of our customers who purchase the tune now FULL CREDIT towards the supercharger system through the spring/summer, should they choose to upgrade during that time.
Another exciting product from RR Racing! After almost a year of development and six months and over 8000 miles of punishing road and track tuning and testing, we are finally releasing our 3XX Supercharger kit for Lexus IS350/300. Our goal for our Stage I kit was to match the power to weight ratio of the top-of-the range Lexus RC-F, while creating reliable, smooth and seamless levels of power that elevate the IS300/350 into a completely different league of performance.
RR430 Stage I Kit Specifications:
Power: For the base "Stage I" kit, our customers can expect to make about 430 crank hp, or 360-366whp (wheel horsepower on a Dynojet dyno, SAE correction) at approximately 6.5psi peak boost pressure, 93 pump gas, equipped with standard PPE headers and a standard 2.5” dual exhaust. Please also refer to the Dyno chart below and in the photo gallery for this product.

We are proud to make history once again by introducing the first intake system (larger cold air box, air filter, and MAF body) to be proven to make power on the IS-F!
Throughout our rigorous testing program, we discovered that the OEM airbox intake is adequate up to about 410 whp, but beyond that level, it becomes restrictive. Tuned header equipped cars seemed to max out at around 410-415 whp. So it turns out that once you add headers and improve exhaust flow, the intake becomes restrictive! Our ability to tune the IS-F’s ECU has allowed us to develop the ultimate intake system by recalibrating the airflow curve to allow the use of a much larger MAF (mass airflow) housing.
RR-Racing Tuned Intake Features:
Additional power gains of 10 to 15 whp over an ISF equipped with our ECU upgrade, headers and high flow exhaust!
Power gains of 60 to 80 whp and 50 to 60 wtrq compared to stock setup as part of our
Performance Upgrade Package!
The MAF tube diameter is significantly increased from 80mm to 87mm. Upgrading the MAF housing is only possible through extensive recalibration of the ECU.
To take advantage of the added flow of the 87mm MAF housing, we utilize a large genuine K&N cone filter with 7” composite velocity stack.
True “cold air” design is fully heat shielded and intake box coated with genuine DEI Reflect-a-gold coating.
Genuine carbon fiber lid is easy to open in order to clean and inspect the filter element.
RR-Racing Tuned intake is compatible with most aftermarket intake elbows (but we recommend the shown RR Racing Titanium Intake elbow offered as an option!).
RR-Racing tuned intake requires a special ECU calibration. RR Racing ECU Upgrade Tune is included with this product.
Please note: If you already bought our tune, you must have your ECU recalibrated in order to use this intake -- please select the "Recalibrate" option, and you will be given credit for the tune portion of the price.
Please note: To provide the maximum power, this intake system must be installed with headers and a high flow exhaust. If you do not have after market headers, then please consider our Performance Upgrade Package that includes this system combined with our PPE headers at a reduced package price.
The chart below shows the gains of our Tuned Intake system.
RR Racing ECU Upgrade Information
RR Racing was proud to make history by being able to offer an OBD device tune for Lexus IS-F engine control unit (ECU)! The Lexus IS-F ECU is a very complex and sophisticated engine management system. RR Racing has been developing this upgrade tune for many months, intimately understanding IS-F ECU's parameters and structures, testing various changes to optimize power and torque effectively while retaining stock fuel efficiency, knock control sensitivity, and other built in safety features. During the development and testing period, we have logged many track hours and over 2,000 miles of road testing and road-dyno logging with many more hours spent on a sophisticated Dynojet dyno at a top-notch climate controlled facility.
So as you can see this was not a weekend project for us, where we slapped on IS-F on the dyno, played around a bit for a day or weekend, and and now we are selling a tune. We had done most of our development on the road, under real world conditions, doing hundreds of runs, datalogs, and hundreds of miles of testing between re-maps in order to determine how the ECU reacts to changes and adjust learning parameters. We have developed a full understanding of the following ECU functions/parameters, including but not limited to:
Direct Injection / Port Injection fuel mapping.
Ignition control (ISF has base ignition maps, cam timing dependent ignition maps, knock correction maps).
Intake and Exhaust variable cam maps.
Torque to throttle mapping (allows us to enhance throttle response).
Two rev limit increases -- 7200 or 7400 RPM (not recommended without our TCU tune).
CEL parameters (e.g., disabling of O2 sensor warning light).
Our on road impressions are that the IS-F pulls much more smoothly and linearly, with excellent midrange and top-end improvement. This was evidenced in our ignition curve datalogs shown below where a combination of ignition and cam timing adjustments resulted in a much more linear and aggressive ignition curve, free of any detonation or large ignition corrections.
After extensive road dyno and datalogs, we headed over to top-notch climate controlled Dynojet testing facility and conducted many hours of dyno tests.

Seibon carbon fiber hood is designed to replace the OEM hood without any cutting, molding, or fitment issues. This hood features cooling vents that improve the efficiency of the radiator and reduce air pressure build-up underneath the car, thereby improving handling at high speeds.
Similar Seibon hood looks very nice on our famous shop IS-F, and it will look even better on your RC F! You can see a photo of an OEM carbon hood on our customer's "Red Devil" RC F (see photos in the photo catalog for this product). The BT Style has the additional cooling vents and a more aggressive top vent.
Made from 100% hand laid carbon fiber with wet clear coat finish.
1. RR Racing Carbon Intake for Lexus XS350 (ISXITK0001) is now available as a discounted option with this tune. You will get more consistent power gains and a better throttle response installing our Carbon Intake system.
2. PPE headers are now available as an option with this product at a discounted price!
3. You can also buy a package that includes PPE Headers and Ark Grip exhaust (see separate product under Performance Upgrade category).
4. To buy this tune with just an exhaust, please buy it as an option with one of the exhaust products we offer.
This tune is for the following models with 2GR-FSE 3.5L v6 engine: IS350 2014 and newer (3rd generation), IS300, RC300/350, and GS350 2013 and newer (3rd generation) models
RR Racing is proud to release another tune for the Lexus IS/GS platform. The Lexus 300/350 ECU is a very complex and sophisticated engine management system. As always, we have worked very hard over a course of many months on developing this tune using our IS350 F Sport shop car as well as our customers' cars. We developed both on the dyno AND on the road. We have thoroughly tested various changes in order to optimize power and torque effectively while retaining stock fuel efficiency, knock control sensitivity, and other built in safety features.
We especially excited to report the results of our IS300 tune. Now IS/RC300 owners can have all the power of an IS/RC350 at a fraction of the cost, by simply recalibrating the ECU!
So as you can see this was not a weekend project for us, where we slapped a Lexus on the dyno, played around a bit for a day or weekend, and and now we are selling a tune. We had done most of our development on the road, under real world conditions, doing hundreds of runs, datalogs, and hundreds of miles of testing between re-maps in order to determine how the ECU reacts to changes and adjust learning parameters. In addition we use our sophisticated in-house AWD DynoJet 424x LINX to fine tune our calibrations. Our ECU tune enhances the following ECU functions/parameters, including but not limited to:
Direct Injection / Port Injection fuel mapping
Ignition control (300/350 has base ignition maps, cam timing dependent ignition maps, knock correction maps)
Variable cam maps
Torque to throttle mapping (allows us to enhance throttle response)
Optional rev limit increase to 7200 RPM (helps the power curve)
We raised the shift points to higher rev limits in Sport and Sport+ modes (rev limit can only be reached in manual shifting with traction control off)
Optional speed limit elimination
CEL parameters
Our on road impressions are that the 300/350 pulls much more smoothly and linearly, with excellent midrange and top-end improvement. One of the most effective changes to the 300/350 is increasing the rev limit to 7200rpm (we can further increase engine rev limit to 7400rpm upon request, but we feel that it may impact long term reliability). As you can see from the dyno results below, the 2GR-FSE v6 continues to pull all the way to the revised 7200 rpm rev limit. This results in significantly more "area under the curve" and better acceleration times.
We estimate consistent gains of 10 whp gains with this tune over a stock car, and 15-26 whp when equipped with a full cat-back exhaust. With tune, exhaust, and headers the gain is 38 to 48 whp (65 to 75 whp for 300)!
All of our extensive dyno testing is conducted in our testing and development facility on a top-notch brand new Dynojet 424x all wheel drive Dyno equipment.
Our tune results are summarized in the following table with supporting dyno graphs below. Please note that you will experience more consistent gains below with our Carbon Intake System as well as a better throttle response.

Please note that the above chart was done by our customer. We will publish a chart on our Dyno soon.
Ordering Procedure
Please select this product and chose the required model year option as well as any other options desire.
Please note that the tune already includes maps for all other common mods such as headers and exhaust.
We will ship you the OBD unit.
You will have to connect the unit to your OBDII port and read the ECU ID.
Then you email us the ECU ID, and we will email back the tune files (one for each of the optional rev limits) applicable to your car.
Updates
If we make any version updates to this tune, we will make any such version updates available to our customer free of charge.

We are excited to announce that after six months of testing, five track days, desert testing, and 9000+ miles of punishment and tuning, we are finally ready to release our IS-F Supercharger kit! Our goal for this kit was to maintain stock drivability and reliability, while creating smooth, seamless, and unrelenting supercar levels of power.
RR625 Kit Specifications:
Power: For the base "RR625" kit, our customers can expect to make about 625hp, or 510-530whp (wheel horsepower on a Dynojet dyno, SAE correction) at approximately 7psi peak boost pressure, 93 pump gas, equipped with standard PPE headers and a standard 2.5” dual exhaust. Using the optional ethanol kit and tune, the power can be increased to 570whp -- approximately 670hp at the engine! Please also refer to the Dyno charts posted in the photo gallery for this product.
Tuned ECU: We have logged countless development hours perfecting our ECU tune for the ISF for ultimate reliability and drivability. No piggybacks or other BS! We have extensively developed the mapping of the stock ECU, modifying literally hundreds of maps and adding additional functionality to the fueling system that allows us to support up to 530whp without fuel system modifications.
Supercharger: Rotrex Supercharger, c38-92 (largest Rotrex SC). Rotrex SC's are extremely efficient and quiet due to their planetary drive system which spins up to 90,000 rpm, much like a turbocharger.
Dry Sump SC oiling system with Oil Cooler: Our system comes with an autonomous dry sump oiling system and oil cooler, so our system does not require plumbing oil lines to the engine, or adding any additional heat input to the engine’s cooling system.
Dedicated Drive System: Rather than using the accessory belt to drive the SC, we designed a dedicated drive system that allows us to achieve the necessary belt tension for a reliable SC drive, without overstressing the alternator, water pump, and AC bearings.
Custom Harmonic Crank Damper: There are some overpriced Japanese SC's on the market for the ISF/RCF that eliminate the factory harmonic damper crank pulley and replace it with a simple machined aluminum pulley. We find this simply unacceptable! Working in conjunction with ATI Performance, we developed a custom tuned harmonic damper than drives the SC belt. The ATI damper has been specially developed to dampen the harmonics of the 2UR-GSE engine at high horsepower levels for the ultimate in engine reliability.
Billet Tensioner System: Most SC kits on the market use OEM belt tensioners, but we took that a step further by developing a billet belt tensioner that is both more reliable and is able to apply significantly higher belt tension than conventional off the shelf tensioners. For added reliability we use Gates Racing Kevlar drive belts and our own double bearing billet idler pulleys.
Dual "Big Bubba" billet blow off Valves: We use not one, but TWO Turbosmart "Big Bubba" 2" blow off valves. Adequate venting is essential for SC responsiveness, reliability, and drivability.
Custom Air/Air Intercooler: We use a large 4.5"x12"x10" intercooler core. These intercoolers are extremely high quality and are manufactured in the USA by Bell Intercoolers.
Genuine Carbon Fiber Intake Tubing: All visible intake tubing is made from genuine twill weave carbon fiber for an amazing look and function!
Please consider the following:
This kit may require a front grill modification, if your car is equipped with our oil cooler or transmission cooler. We recommend both coolers, if you track your ISF. We offer an ABS honeycomb mesh to retrofit into the ISF stock grill (please see ISF Grill Mesh option). It comes with a F Logo.
We recommend to buy a boost gage. We offer a complete boost gage kit (also see our Gauges category) as an option with this product.
We also recommend to buy our Air/Oil Separator (AOS) -- although not required for the supercharger. Please let us know if you don't have an AOS.
The passenger side fog light either has to be removed or the back of it needs to be trimmed to fit the air intake lines. Soon we will offer an option to buy a specially modified fog light.
During installation the bumper rail will have to be removed to fit the intercooler. It is possible to preserve portion of the rail on both sides with an opening for the intercooler.

Recently, we developed an oil cooler kit for the 2GR-FSE engine in the Lexus IS350. The best place to locate the oil cooler was directly behind the Lexus front grill badge. In order to facilitate airflow to the oil cooler, we designed a hollow billet badge, available in both "L" and "F" configurations.
Each badge is CNC cut from billet 6061-T6 aluminum plate. We then use a powder coat base coat and secondary clear coat for added durability. Standard color is silver, but we also do custom powder coated colors (see product photo for color samples) on request, for an additional cost.
Please note that we have not tested this badge with Lexus PCS system.
Compatibility:
Fits Lexus IS250/350 2014 and newer models only
This tune is for the following models with 4GR-FSE 2.5L v6 engine: IS250 2066+ models.
RR Racing is proud to release another Lexus tune! As with other Lexus models, the IS250 ECU is a very complex and sophisticated engine management system. As always, we have worked very hard over a course of many months on developing this tune using our IS250 6 speed shop car. We developed both on the dyno AND on the road. We have thoroughly tested various changes in order to optimize power and torque effectively while retaining stock fuel efficiency, knock control sensitivity, and other built in safety features.
We admit that we were surprised at the power gain we were able to extra from this car! As you can see from the Dyno charge below (and in the photo catalog), we were able to gain a whooping 20 wheel hp just from the tune!
As with all of our tunes, this was not a weekend project for us, where we slapped a Lexus on the dyno, played around a bit for a day or weekend, and and now we are selling a tune. We had done most of our development on the road, under real world conditions, doing hundreds of runs, datalogs, and hundreds of miles of testing between re-maps in order to determine how the ECU reacts to changes and adjust learning parameters. In addition we use our sophisticated in-house AWD DynoJet 424x LINX to fine tune our calibrations. Our ECU tune enhances the following ECU functions/parameters, including but not limited to:
Direct Injection fuel mapping
Ignition control
Variable cam maps
Torque to throttle mapping (allows us to enhance throttle response)
Rev limit increase to 7200 RPM (helps the power curve)
We raised the shift points to higher rev limits in Sport and Sport+ modes (rev limit can only be reached in manual shifting with traction control off)
Raised the speed limit to maximum allowed by the ECU of 160 mph
CEL parameters
Ordering Procedure
Please select this product and chose options.
We will ship you the OBD unit.
You will have to connect the unit to your OBDII port and read the ECU ID.

Other FAQs:
Why do you provide a range of “tuned gains,” not a precise value?
There are many factors that influence dyno results and lead to variability in power measurement. Additionally, your ECU is constantly making changes based on sensor feedback that significantly influence engine output – and this is the case even on a stock ECU. So bottom line is that regardless of the mod you install, actual gains will vary. We make every effort to provide actual, factual, and transparent dyno data for our customers.
Do you recommend aftermarket intakes? At this time, we do not recommend any aftermarket intakes that remove the factory airbox.
Can you work with me or my tuner to improve my tune?
In most cases yes. If you plan on taking your car to the dyno, please contact us ahead of time in order to discuss the type of datalog data we need in order to fine tune your ECU, should it be required. In most cases, custom tune fees will range from $200-$300.
What about that Supercharger Kit you guys are working on?
We may release a supercharger kit for the Lexus IS350 in first quarter 2017. At this time, and until further notice, we are offering all of our customers who purchase the tune now partial credit (the amount to be determined based on SC kit pricing) towards the supercharger system through the spring/summer, should they choose to upgrade during that time.
For IS-F owners looking to improve the cooling capacity of their radiator, or those suffering from radiator failure common in higher mileage IS-F's, RR Racing is pleased to introduce our Performance Radiator and transmission cooler kit. Our upgraded transmission cooler is required when replacing the radiator to a Koyo unit due to the lack of the OEM transmission cooler. The results are much improved cooling for your engine and your transmission.
Please note that even if your radiator did not suffer a failure, most likely it is clogged with debris (especially in the back of your radiator). Any ISF can use a new cleaner and larger radiator!
Key features include:
Upgraded genuine Setrab or Koyorad core transmission cooler with nearly triple the cooling capacity of the stock transmission cooler. Also features genuine Mocal fittings.
Koyorad performance radiator 48mm two row, high density "Hyper" core which will bolt to the factory equipped fan shroud.
All aluminum construction for better cooling and durability.
