So I purchased my 2016 Lexus LX with the goal of supercharging it at some point. After deciding to go with Harrop I pulled the trigger this June and installed the S/C in my garage over a weekend. Needless to say the install was super easy and straightforward especially with an extra set of hands to help. The truck starts, idles and drives perfectly and if I didn't tell you it was supercharged you would never have known! But there is one exception which happens only sometimes at WOT and that was the transmission not shifting fast enough and bouncing the rev limiter or hitting fuel cut right at redline.
So the next step was to find a tuner and get my truck properly tuned right? Wrong.
There was 0 support for 2016+ models due to the ecu... I pestered so many different shops and tuners but the only one I found was VFTuner aka OVTuning and they said that they did "crack" the 2016+ ecu's but I would need to send my ecu out to them in S. Korea to have it unlocked and calibrated so that a tune can be performed. So I bought a 2nd ecu so that while my first one is sent off I could still drive my truck and thank god for that because long story short it took 5 months to get a working ecu back! It was a roller coaster of emotions during those months but I'm glad to have done it because now the truck drives absolutely perfect!
Those of you guys that want to S/C but are hesitant because of the tuning ecu issue no longer need to wait because according to my tuner I am the guinea pig and they are building a good tune file from scratch. So far we have just baselined to make sure the engine isn't going to melt down and fixed the fuel cut and shifting issues. The next session is to see how much power we can extract and the final session will be when I install the stage-2 upgrades (650cc injectors, 80mm pulley) which should be sometime in January.
Here are some pics and vids to keep you guys entertained
