Even with 8.4cr and 93 octane? Hmm. What would you expect for the top couple of rows?
There seems to be a consensus brewing.
I seem to recall adding two degrees to the top of the map back a year and a half ago because I felt there was too much heat in the exhaust because of the (I thought) overly retarded timing. I saw a few others running more and felt I could safely add a couple.
Are you using low or high compression pistons with the E85?

IMO the 183 row is really the one that's kinda aggressive, and maybe the 212 by 1 or 2, top row aint that bad.
and y'all have proper fuel and not CA 91oct water, so I don't even think it's that bad.
also the spark is not 8x8, that's the afr target table, unless we're looking at different tables.
...I'm not really impressed with how late that thing comes on though, that's for sure.

On my GT3271, I found a lot of spoolage by not running pig rich while it spools. I ran it around 14:1 at 100kPa, 13:1 at 140kPa, etc, tapering to target AFRs when you get to target. That made a very very nice improvement in both driveability and spool. Worth a shot since your posted AFR target table is richer than needed at very low boost.
