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 AWD Stage III. Our goal for our 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. Our Stage III kit for the 350 AWD exceeded this goal!
RR490 Stage III Kit Specifications:
Power: For the "Stage III" kit, our customers can expect to make about 445 whp (wheel horsepower on a Dynojet dyno, STD correction) at approximately 9.0 to 10 psi peak boost pressure, Ethanol blend is required for Stage III, equipped with standard PPE headers and a standard 2.5” dual exhaust. Our Stage II kit makes about 410 whp SAE. Please note that we are shipping Stage II kits -- Stage III upgrade is available as an option. Please refer to the Dyno charts below for RWD model (similar power is expected for AWD).
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 c38-92 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.
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.
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.

Weight savings is the key to extracting the most performance from your Lexus, especially when it comes to cornering, acceleration, and braking. For most Lexus models, the OEM battery weights a whopping 42lbs! Up until recently, the only option to save weight was to use a lightweight 10lb AGM lead-acid race battery. Problem is, they have very poor cycle life and most of these batteries last about six months under normal operating conditions.
This product fits all IS350/300 2014 and newer models as well!
Enter the new Lithium battery technology. At just 4.9lbs, this battery is rated at 16Ah reserve capacity and 840 cranking amps, all while saving about 37lbs of weight off the front of your vehicle! Our kit includes terminals, custom battery box/bracket for plug and play installation.
An exclusive feature includes an LED battery fault light indicator on the battery itself plus it can be programed into your EFIS or wired to your dash with a simple 12V LED light that alerts you to the state of charge and state of health of the battery.
The battery management system protects the cells from over discharge, over charge, short circuit, excessive cranking and cell balancing technology PLUS this is redundant for another layer of protection. The lithium battery we use meets the requirements set forth from numerous airplane engine suppliers, including Rotax engines, ULS Power Engines, Viking Engines, and Continental engines plus these aircraft batteries are used in many aircraft manufacturer straight from the factory. So you know that if these batteries can be trusted on an airplane, you can trust them to power your car!
Please note: We recommend using a lithium specific charger for maintaining batteries for cars that are stored for more than a few days at a time. Lithium batteries require lithium-specific chargers. We highly recommend to buy the optional charger we sell with this product. Please refer to installation instructions for proper maintenance and charging of this battery.
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.

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.

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.
At RR-Racing, we build performance parts, not show car parts, but every now and then, we develop a product that both looks good and serves a function. 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

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.
This package includes two of the best quality products on market for Lexus 3XX --

We estimate consistent gains of 38 to 48 whp(65 to 75 whp for 300) 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 that comes with this product is for the following models with 2GR-FSE 3.5L v6 engine: RC350, RC300 AWD 2015 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.

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 38 to 48 whp (65 to 75 whp for 300) with this package!
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.

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.

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.
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:
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.
Ordering and Pricing:
Customer who bought the OBD tune from us are eligible for credit -- please select the option Recalibration option and select Own Tune. Please also tell us what model year is your IS-F by selecting the appropriate option.

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 II" kit, our customers can expect to make about 400 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 c38-92 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.

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 that comes with this product is for the following models with 2GR-FSE 3.5L v6 engine: IS350, IS300 RWD 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.
We estimate consistent gains of 38 to 48 whp (65 to 75 whp for 300) with this package!
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
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.

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.

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.

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.
