Just like the title asks, how lean are you going / how much more advance you running with E85?

Timing really doesn't make a big difference. AFR's make a huge difference.
I like to run around 16* advance at 15 PSI and go down from there .12.2:1 gas AFR's. 12:1 makes very nice power!

that would be an interesting test, pick a safe boost, like 15psi, safe AFR whatever that is and see what timing looks like... in theory you get to see best timing without knock, maybe we learn something?

Noticed the same thing here. Timing hardly makes any power difference but does lower egt's. A/F makes quite a big difference especially at higher rpm's.

Any input on timming split, I'm getting sputters and spits at 5k and it hits a wall. Using the same timming map as 91 and I had 0 degrees split. Any input?
