2010 Camaro SS - Video after E85 Tune

[lazerlemonta]

One of the major issues with stand alone E85 tunes using it from gas stations is chasing stoich. One day you may be fat and the next lean. If your going to run pump E85 the flex fuel set up is not that expensive and is a much cleaner tune. You could always carry an E85 tester and after every fill up drive 10 minutes and test the fuel and set stoich off alcohol content. Dialing in your VE would be a great benefit to your stand alone tune as well. Did you recalibrate the weight of the fuel? this may be why you MPG has not decreased much do to tricking the computer. I went from 24MPG to 19MPG on my set up. Your correct on throttle response though much crisper. The only other thing is the throttle will hang a bit (reduce at a slower rate then on 93) on occasion. I had great results with it, bolt ons and 1.85 rockers went 11.56@120. Good luck OP
