I have a question regarding ethanol & gas blends. I did some additional reading on Ford's OAR adjustment, and it appears that it uses the frequency of the fuel ignition sequence to determine whether there's knock, and adjusts timing and boost accordingly. I found some additional E85 pumps nearby. If I blend E85 and gas in the appropriate ratio, will the OAR allow more timing advance and keep the correct stochiometric mix? ZFG said I would see stock or lower boost using E85 on a stock fuel system in a Gen 1. Five Star said I'm limited to E30 because of the fuel delivery system. But I'm not as concerned with peak boost as I am with part throttle acceleration. I think I just need some additional timing.
