I need this mod. And E85 is not that affected by DA? Double killer.

It still is very much so. Just not as much. Its cooling effects help in hotter weather among other things ive read in the past that I cant recall. Some old bomber planes back in the day used to run ethanol to help performance at elevation too.
But higher DA will still play a major role imo
