@@finkenf10 Only if he converted to the gasoline scale. If his A/F was a true 11:1 on e85 that's way too lean. E85 likes something like 9:1 under power. I think 11:1 is stoich for e85 if I'm not mistaken. Most guys convert to the gasoline scale in the ECM cuz that's what they're used to dealing with and most gauges won't read below 10:1 A/F.
