SE take two! Err, make that three!

not to mention many applications can use flex fuel sensors now> i have my flex fuel setup awaiting tephra to finish the code/testing for it, can't wait

But yes, I agree on both parts. A tuner familiar with e85 shouldn't have issues with these inconsistencies as you tune to the lower denominator.

Quite true, great advancements for sure! A real FlexFuel compatible tune would be amazing in an Evo. So with Tephra getting this implemented, I'd imagine you just get a tune on 93, and a tune on real E85, and the ECU automatically interpolates between the two maps as needed based on sensor readings?

That is the idea I believe. But I don't know how much you can control for e levels. I would want anything above 70% to be basically balls out but below that be much much safer as I am just putting regular gas in for distance at that point not performance. I'd have ot ask how all that will work but that is the general concept.
