E85 Timing Maps
This is with 9.8 VIII turbo. ECU boost control with GM 3-port. (Dynoed about a month ago at 362tq/342hp on a mustang. I switched to a metal intake since then, which looks to provide ~0.5-1 psi higher than the rubber one from ~5000rpm and up, therefore increasing top-end power a bit...)

Edit: Timing is scaled as timing plus 10. (To move the graph higher, so that its easier to read for me, i did it back when i had neg timing at spool-up, DLL does not show neg values)):

mplspilot,
your log doesn't match the timing map you posted.
15* at 4k and 32*+ at 7k?
EDIT: nevermind I looked at the Value on the left and saw the scaling was different on timing.

it's freaking massive with this tiny turbo
After switching to ethanol, I found that I needed to add in about 3-4 degrees to my timing map just to keep from misfiring. The extra fuel volume was too much at the miniscule timing I was having to run on pump gas. After I added the timing in, the car pulled clean and I was able to add an additional 5-6 degrees in most areas.
