Re: falls flat on the face!
I wouldn't run E85 at 12.0-12.5 unless you are really trying to push it to the edge. E85 isn't that consistant of a fuel.
As Carl mentioned, did you set the globals up for gasoline or E85, they would be much different. What are his LTFT and STFTs at? Also, if it is misfiring, that will show as lean on a wideband, because the oxygen doesn't get used up.
