Pump Gas A/F vs. E85 A/F..
 

what should my A/F ratio be at WOT on E85? What about idle?
Since E85 has more oxygen and some water in it you would think that the A/F ratios would be different from regular gas, wouldn't it? Help out!

i think i am shooting for 11.5s, pretty much the same as gas. some people do 12s.
I am out of practice and that shit is way in the back of my mind as the car isn't even close to running yet.
But i am sure of those numbers.

Your really going to be aiming for aroundd 9:1 AFR. But your wideband guage will display on a gasoline scale. you'll want to tune for 11.5-12.0:1 WOT and 14.7 cruse AFR on you guage but just keep in the back of your mind your realy alot richer
