I don't know what the burn ratio of E85 is compared to alcohol, i know nothing about E85, but i would put the pill in that Rons recommended for a starting point, pull the high side chip out and bring it up on the converter that you have. Change the pill up and down until you get the highest stall and that should atleast get you down the track.
But as David says alcohol runs great with a bowl and is not much more than E85, in fact about $2.15 a gal. for me, or $120.00 a drum. And i know about like of $'s, i'm retired and Uncle doesn't pay me all that much per month.
