    2007 E38 Base Corvette E85 Question

    Starting my E conversion on my weekend warrior. Getting my tune setup I've ran into an issue. Under fueling I don't see PE EQ for alcohol. Does the ECM reference the gas ratio for ethanol or is there another table I'm missing? I'm also concerned about my stoich. Tune is scaled 50% (double stoich, half IFR, half AFR Terms) will I have to make any adjustments for E85?

    some early e38 didnt get the PE alcohol table so it uses the petrol one, the scaled tune fuel wise is fine as it corrects itself so it will still work normal for flex i have been using it that way for ages, as longs as your injector data is good it will be fine
