Chevron agreed with me btw, non-oxygenated 93 octane gas gives better mpg and better power than 93 octane gasohol.
If you're running e85 at 12:1, there's no point in having gone to e85, because you sure aren't going to be running 14:1 compression with a 12:1 a/f on e85.
My knowledge comes from 9 years of EFI tuning experience and having tuned hundreds of cars ranging from all motor to 40+ PSI of boost, high compression, low compression, 4 cyl, 8 cyl, leaded gas, unleaded, ethanol, methanol, gasoline, from 200 too 700+ whp.
Us in the auto performance industry make fun of people like you every day. Paper Engineers. You can state your theories based on high school chemistry text books all you want. In the EFI world we deal with reality, not term papers.
If you're going to argue at least come up with real information. Ethanol does nothing but help. It is an anti-detonation agent. I've dealt with many cars on E85 and so far it's working as good or better than C16 for us, running reliably in the 30 + PSI range, 650+ whp, and 10:1 CR.
Of course being a member from 08 I shouldn't expect you to understand the complexities of the real world I guess.
