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

VipViper - this is a good news, thank you for posting this. For the longest time, I've wondered about information pieces you mentioned. I have recently acquired a GM truck (an FFV) equipped with an engine with a high compression ratio (11:1), direct injection, and variable valve timing. GM engineers managed to bump the engine output 25 hp and 33 ft-lbs just from using E85; not to mention the pleasing way the engine reacts to throttle inputs while on E85 and it even sounds different.

I thought a Z34 could benefit from using the E85 if it's so equipped (ethanol-resistant hardware first, then capacity) since the VQ37VHR runs a high enough compression ratio. Now, if you had the data, would you mind superimposing the injector duty cycle and the AFR?
