Description:

RR Racing Lexus IS/GS 350 OBD ECU Upgrade Tune for sale.

$200 FIRM picked up local in Orange County, CA ZIP 92807 (shipping extra).  This item will come with original box and all contents originally shipped from RR Racing. 

I sold my 2015 GS350 RWD and parted it out a few years ago and just found some additional parts while cleaning out the garage.  

RR Racing lists this as compatible with the 2GR-FSE 3.5L v6 engine: IS350 and IS300 2014-2016, RC300/350 2015-2016, and GS350 2013-2015 models.  You may need to reach out to RR Racing to upgrade the tune to fit your specific vehicle.

*Even if a RR Racing tune upgrade is required with any applicable fee is, you're still looking at a deep discount as this is $549.99 (plus shipping) brand new.

• 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)
• Rev limit increase to 7200 RPM (helps the power curve)
• Raises the shift points to higher rev limits (higher shift rev points require use of paddle shifters for maximum performance)
• Raises the speed limit

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. 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). This results in significantly more "area under the curve" and better acceleration times (for AWD).

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)!
