As for the E80 map, did you check your fuel trims and afr where you were seeing large knock correction? E85 does not take a lot more timing in the midrange (3k - 4k)than pump gas.. I stopped seeing gains with just a couple degrees over my 93 map.. Up top is another story. Also, Unlike Gasoline E85 knocks on the rich side, not the lean side.
If you were still having fuel trim issues on pump, E85 is probably going to be worse due to increased flow rates.

According to the EcuTek logs my AFR was 13.78 when it first pulled timing. It continues moving slightly leaner, and pulling 5 deg. My AEM wideband certainly seems to show higher A/F ratios than the ecutek logs. I wish I had a better way of lining up these two data sources.
I always see a lean spike (14-17) when I'm about to hit boost, then it goes rich. I didn't go past 4k during my last log since it pulled more timing than usual.
This is still the basemap FWIW.
