How much timing are people running with their E85?

Also, what AFR should I be shooting for when I am at WOT and also at a normal driving speed.

Thanks

I'm hovering between 18-20* of timing with my 2.8" pulley, still not getting any kr but i don't plan on adding any more timing at this point. My car is non-i/c'd.

I would shoot for as lean as you can get but don't go over 12.2-12.3 that's asking for trouble. For my DD tune i like to set it at 11.6-11.8 but when i hit up the track in a couple weeks i'll probably be around 12.0-12.1 give or take.

Hope that helps!

On my SSEi, I'm currently running 11.8 afr with 19* of timing with a 2.8 pulley (max boost is 13.5psi). I still need to monkey with the tune. On the street, it's running great with minimal blips of KR <1* for a line or two on my scan logs every once in awhile.

nah, it's oxygenated yes, but running it richer than gasoline has no positive effects. Leaner=better in this case.
