I would be concerned about the effect that the E85 would have on the fuel system hardware if exposed to it for over a week.
Marc,

Couldn't the target AFR values be adjusted to account for the E85? I would think that running in closed loop is going to be his best shot at passing.

Maybe I'm missing something. If so, I'm sure you and/or Dom will set me straight.
