Aside from the normal stuff you have to change, i mocked up the tune according to a 2012 Honda E85 flex fuel car, using stock gm settings.
As far as timing however, which tables do i need to actual use for E85, i've setup the multi vs comp table already, so now which table effects spark, do i use the "Flex fuel spark" or the AFR correction Alcohal adder? and what do you suggest as a good timing base setup? I can show you what i have so far if you wish?
