GIAC will not be doing E85 maps soon, because of the different knock properties of E85 compared with gasoline... wonder if Cobb has similar thoughts. Apparently they have seen (other platforms I take it) continue to advance without sensing knock... so a more severe detonation I guess. Would like to know more.
I asked Rob about it and its on the list, but not a priority as of right now. I dont know that i would push an E85 map and make it OTS if i was Cobb, leave it to the protune shops. Between mixing fuels and the inconsistency of ethanol % in E85, some people may 'eff it up.
