Running E47 and seeing 80% Injector Duty Cycle at WOT. Doubt there is enough stock injector to pull it off. I also see fuel rail pressure dropping to ~50psi from 58 on the 1:1 mix of 93 & E85.

I don't believe in running over 80% IDC. Running PE of .84 lambda and Stoich of 11.97.

K&N Intake, Solo HF Cats, MBRP 3" X-pipe exhaust & tune.

The E47 is ~99 octane and performs well. Since it's not my DD I don't mind blending it. 27* advance at 6k and no knock retard.

E85 takes ~30% more fuel than pumpgas so your mileage will suffer. I see 18-19mpg on E47.

Vince is a great guy, I helped him work on the E85 tune for the 4 cyl turbo LNF in Cobalts. It has fueling issues stock with E85 as well. I never could get the LNF over ~70% E but it was a DI engine. He might be able to tweak the fuel pump up, IDK.
