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

Whatever u take from this dont fall into the "e85 doesnt work crowd" because ud be egregiously wrong. Unfortunately your setup just isn't working with e85. No one has ever made anything but less power with e85 on the same timing as gas. Thats just how it works. Our platforms tuning software suppliers need to step it up imho.


So if thats correct im not sure why you got more with fuel trimming only. Clearly i need ecutek! Turner can only run 28* same as gas.

Tried what?
