Only do this if you're actually going to test the E85 you get because it's quality varies wildly station to station and sometimes even fuel delivery to fuel delivery. I've seen as low as 40% and as high as 89%. The required fuel map to run it safely is very different for 40% Ethanol vs 89% Ethanol. OFT E85 tune is a single map with an expected average 70%... which may not be correct for your area.

What you instead should do if you want to use E85 is to get a FlexFuel setup, which you /can/ do with OFT, but is better done with EcuTek. Realistically, you should save your dollars and do things correctly for the best experience which means a good header and a good tune on EcuTek.
