^ he's right. calling it 'autotune' to begin with is misleading. it's not tuning anything. it's trying to save it's own life. it cares nothing for optimization.
one could argue that fuel trims are fine because once they stabilize the AFR is fine. it's simply not true, especially on this car with it's two completely independent, interoperating fueling systems (port and di).
just look at some of the guys running OFT on e85. sure their trims 'learned' over time, but they still have wildly variable AFR every time the go into open loop. i've seen logs of the OTS e85 map with guys running 10.x:1 on e85. certainly not a good way to make power.
