E85 Timing & A/F Ratio

I recently switch over to e85 and was wondering if anyone can share their ignition tables with me to get a general idea of what they look like. Ive read somewhere on here that it usually likes for the timing to be retarded instead of advanced as well, some say as much as 6-10 degrees actually. Just want to get an idea before i get it dyno'd, Still waiting on some parts that i want to install before i decide to go ahead and actually do it. Ive been running auto tune to get a fuel map that would actually run properly and got that dialed in already with a couple of rides. What A/F are you running on e85 also? Ive seen several members have gone with 11.5:1 for 0-60% throttle and 13:1 at 80% to WOT. Thats what im currently running and it seems to run like a champ.

-Thank You

What I'm using for E85 as both of my bikes like negative numbers over advanced timing. Remember each build is different so what my bikes like yours may not... Hope this helps
