just need to get a good tune.

the EFI system will handle different fuels if calibrated and adjusted for it.
will basically come down to an adjustment of timing.
engine doesnt care or know what you put in there as long as it blows up.

ehtanol can be hard on the fuel system though and eat away at o-rings
and such but I wouldnt worry about it. just keep and eye on things
from time to time.

you need larger injectors too because you have to inject more of the stuff. Its also very corrosive so you need special seals in your fuel system and i believe you need a special tank too. I dont know about the needle and seat in the injector though, gasoline has additives to lube 'em and the pump. Ethanol doesn't. I believe it has an octane rating of 110. You'll get horrible mileage with it, they did a whole article in car craft about it. They ran it in a blower motor and made 500 horse with a pretty much stock blown 350. If you go to car crafts website they might have that article on there they tell you how to run it. If I lived in the midwest i would totally convert my car to run on it, its pretty much cheap race gas.
