I am new to tuning and hp academy. I have a 2010 lexus gs350 awd. A 305hp 3.5L v6. Yes, stock this is a grandpa luxury sedan. But I have got it dialed in where I want it except tune. This ecu is apparently extremely hard to crack and reflash. Any tips to reflashing something this complex ? No one makes a jumper harness i am told and tunes are basically not heard of for this vehicle, even some standalone company's have said it isn't possible due to the direct injection fuel injectors.
There seems to be quite a few places offering 'tunes' - are you more interested in doing your own, though? In which case this may be helpful? - https://www.vividracing.com/lexus-gs350-ecu-tuning-i-12448.html
