How do I properly adjust for different grades of ethanol?

[Parts-is-Parts]

I had my car Dyno'ed with e77 and had a 11.4 A/F
My most recent tank of ethanol tested at E92 and the car is in the high 12's for A/F

Can anyone give me the proper way to make adjustments?
I have a pro racers package and know my way around it.
Thanks in advance!
