Gains from E85 (ethanol) on an N/A bolt on 370Z

Im pretty sure I remember seen a guy on here running with E85 and showed gain which was with Uprev last year.
There is an issue somewhere in the tuning because Uprev can advance it to 32 at high load/RPM

This for me? My tuner didnt say he couldnt set the timing higher, he said it wouldnt take it. The ecu and or uprev wont let him do ****. And if my post on why e85 lost power over 93 makes sense to anyone else besides me than thats why. 28* just isnt enough nor good enough to preignite the mix soon enough. Im testing the dyno and tuner again real soon going back to 93 and going back to 2.5" CAI. Ill find my power loss if it kills me.

It does in some cases (other platforms I've done). However my original statement about it being more economical turned out to be false -- the eco calculation on the dash is junk, not accurate on E85, and sadly not even accurate on pump gas.

That's because UpRev is crap.

28* still makes more power with E85 over pump gas. I added zero extra ignition advance and still saw 5-6hp gained.
