I think my title probably explains my question pretty well. When I built my 94 LT1 based 383 I had easy access to race gas, and I built it with 12.5 to 1 compression. Now that access has dried up and I have to back the timing off substantially in order to run it on 93 octane, leaving lots of power on the table. I have tried a snow methanol injection system with limited success in controlling the detonation. I do have an E85 station only a few miles from me, so I am wondering if it is possible to set up an EE based system to understand a flex fuel sensor so that I could convert over to running E85? Thanks.
