gasoline runs 14:1 stoich more or less, ethanol needs about double the amount of fuel to air, around 8:1. you'll need to be able to inject 2x the fuel or more to run alcohol. if you have a standalone you could try for E85, which iirc runs a stoich mix around...10:1? slightly less taxing on the fuel system....however your fuel system soft parts have to be capable of handling the extra alcohol.
