I'm running 2* MORE timing on E85. Thats it, the car wasn't, making any power above 27*.The car is 13.2 AFR N/A on both set-ups!!!

LS1408CP was present while this tuning was going on.

Basically, just gotta be careful with the winter blend of ethanol as its not as high of a octane as spring/summer

why would you want your AFR like that? stoich should be 9.7 on e-85. did you change your afr on your wideband so 1 lambda was reading 9.7 instead of 14 like regular gas?

My tuner adjusted the AFR accordingly. Yes you are correct though
