LEXUS RC & RC F sport RC3XX RWD PERFORMANCE UPGRADE PACKAGE

Manufacturer Discription:

This package includes two of the best quality products on market for Lexus 3XX -- PPE headers and Ark Grip exhaust with burnt tips. 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 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: RC300, RC350 RWD 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. 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.

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.
