Yes. I didnt see this post until i replied to the last one. Your running a ton more fuel. And everyone needs to remember that after stoich, none of the other fuel even burns because there isnt any oxygen to burn it. It is there for internal cooling wether its gas, e85, or lpg.

If you leave your wideband calabrated for gas (which allot of people do when running e85 because allot of the gauges have trouble reading out in the 10:1-6:1 range and because lambida your dealing with such small numbers that at a glance are hard to take in) i usually try to target around a 12.5:1 on the gauge although that is not really the afr.

Im sure this will cause more confusion with other people but we go through this everytime an e85 thread comes around.
