Does anyone know how much timing advance is pulled when the IAT reads too high etc, say 35 degrees plus ? The LS1-LS2 engines pull a fair amount of timing with heat soaked MAF sensors, and rising intake temps, and hence the popularity of the OTRCAI. I just did a 450 km round trip in my soarer V8, and I'm still blown away with how that thing pulls on the open road, and around town for an essentially stock car, so I know how these lexus V8's should go
I really think this is the issue, Ive checked and replaced just about everything.
And the car really does motor when cold. I'm going to try a nice cold air intake, as it is only getting hot air at present. Failing that I'm going to clamp the IAT sensor at around 2.5k ohm, atleast for testing purposes.
