The reason I am asking I know for sure around where I live the Fuel is 90-10 blend .
I looked at a stock tune but B3660 is 0 and there is no difference in the OL Fueling Standard and Ethanol values .

A 90-10e blend is close enough that the pcm can easily compensate with the trims. And not affect OL much. It only when you get up to the 15-85e That it needs to compensate.
