5 ltr. beater

ok i just flashed my ecu last night with the help of my buddy ,and my afrs under WOT were bouncing anywhere between 11.8-12.0 and the car felt good with 0 knock.
today as im driving and enojying the power of e85, my afrs are now for some reason under WOT between 12.0 and 12.4
ive read numerous threads on E85 tuning and it seems that the safest way to run e85 is around 12.0-12.1.
am i hurting anthing by it going up as far as 12.4 on the stock turbo and stock intercooler?
im getting 0 knock and the car feels great (not to mention the incredibe spool up time).
please let me know what u guys think

well wen we tuned my car it was round 11:30 pm and it was about 58' degrees outside. yesterday afternoon when i was doing a few wot runs it was about mid 70's.

e85 is magic. I have ran into the 14's afr on my galant, makeing 600+whp. You should be fine, however you are going to have to feel your car out to get a good Idea of what afr it really wants. My galant would make more noise at 11.0 then at 14.0 afr. I am talking about 35psi, on a 37r.

just thought id give an update:

prior to filling my tank with E85 i tried to empty out the fuel that was already in the tank but i could only get it down untill the low fuel warning light comes on (which generally means u have a few gallons of fuel left.)
so what happened is that i was tuning my car with a mixture of race fuel and ethanol.
we retuned my car and everything so far for the last 2 days has been just fine.

Yep, more Eth = leaner.
Less Eth = richer.
