What is an E85 sensor? I've never heard of such a thing. The O2 sensor will read a lean condition, but you just increase fueling. And with E85 you can run leaner, and still be relatively safe. When I tuned my MS3 for it's initial "E blend" of 25% E85/75% 91, I threw in the 25% and drove around normal for a couple days to get a baseline on the stock tune. Under WOT there was nothing implying any dangerous conditions. And this is on a boosted motor, mind you. And you would tune FOR the E85. not juust add it willy-nilly to any map.
