#IS300 ECU TUNING FULL#
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. This results in significantly more "area under the curve" and better acceleration times (for AWD). 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 (AWD only). One of the most effective changes to the 300/350 is increasing the rev limit to 7200rpm.
Our on road impressions are that the 300/350 pulls much more smoothly and linearly, with excellent midrange and top-end improvement. Raises the shift points to higher rev limits ( higher shift rev points require use of paddle shifters for maximum performance).Rev limit increase to 7200 RPM (helps the power curve).Torque to throttle mapping (allows us to enhance throttle response).Ignition control (300/350 has base ignition maps, cam timing dependent ignition maps, knock correction maps).Direct Injection / Port Injection fuel mapping.Our ECU tune enhances the following ECU functions/parameters, including but not limited to: In addition we use our sophisticated in-house AWD DynoJet 424x LINX to fine tune our calibrations. 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. 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. Now IS/RC300 owners can have all the power of an IS/RC350 at a fraction of the cost, by simply recalibrating the ECU! We especially excited to report the results of our IS300 tune. 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 developed both on the dyno AND on the road. 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. The Lexus 300/350 ECU is a very complex and sophisticated engine management system. RR Racing is proud to release another tune for the Lexus IS/GS platform. **TUNING FOR 2018+ IS/RC & 2017+ GS MODELS IS CURRENTLY NOT AVAILABLE** To buy this tune with just an exhaust, please buy it as an option with one of the exhaust products we offer.
#IS300 ECU TUNING UPGRADE#
If you are converting your Lexus into a dedicated race car, you can also buy a package that includes PPE Headers and Ark Grip exhaust (see separate product under Performance Upgrade category).ģ. You will get more consistent power gains and a better throttle response installing our Carbon Intake system.Ģ. RR Racing Carbon Intake for Lexus IS/GS 350 (ISXITK0001) is now available as a discounted option with this tune. Please note the following important facts:ġ.
