Ethanol vs non-ethanol, problems?

[larry_arizona]

E85 needs injectors that are full stainless internals, ideally you want a flex fuel kit, there are many kits available for most GM performance cars after 2009. Also you run out of fuel pump pretty quick depending on how much HP you are at. The flex kit adds a alcohol sensor and ties into your PCM wireharness. Then your tuner can do two tunes, one for E85 and one for 93. Then the tune can be scaled between the two fuel extremes based on
%alcohol reading from the alcohol sensor.

6-8 degrees added timing is a ton of power and alcohol behaves like a liquid heat exchanger to cool intake temps on forced induction applications.

There is one HUGE problem with E85, the black goo of death......it’s real and not much you can do about it other than cleaning injectors and pulling pump to clean.

Alternating e85 and 93 helps, but eventually the goo will get ya.
