I don't have much experience tuning e85 setups. The fueling side changes seem pretty basic and I plan to change the following:
Target Stoich values
Power Enrichment Aircharge and PRatio tables
Startup Inj PW (Startup Base) (multiply this by about 1.25)
But I am curious what to do with idle, part throttle, and wot timing. WOT timing I'm inclined to leave alone and add as I move along, but in general how does E85 like to run off WOT? I know from tuning pump gas setups with larger cams the idle timing becomes very touchy, less can be better is the norm, but I don't want to not run enough.
