I lost power
. Best description...Higher octane fuel is slower burning. If your not igniting it soon enough then u arent giving the fuel enough time to release its energy. What u need to take away from this is that your ecu/tuning system is inadequate for use with e85 on your application. 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.
