First I am working with Mr Winfield to see whats going on. But here is the situation. I put a 93 tune on the truck with no issues. When I tuned it on E85 (on second steps) the truck thru 3 codes P2198 O2 sensor biased/stuck rich (bank2 sensor 1) P2196 same as the other only bank 1 and P05A1 grille shutter A minimum/maximum stop performance. Anyone ever see these codes? Trucks performs fine with no noticeable issues. Anyone ever have these codes?

I threw that code once after I bounced it off the rev limiter. Cleared them and no issues.
Those codes were on my first tank of E85 I had 1/4 of 93 mixed in. Cleared up once e85 circulated all the way through. Winfield will get it sorted.

Is this your first tank of E85? If so how much 93 was in the tank?

Pump E85 is a roll of the dice.., get your self an E85 tester.

I agree. I’ve definitely noticed hotter fuel in different cities. A little town in west Texas has the best E85 I have found, gauged by the butt dyno.

I monitor E-content real-time and have the Fuel-it app calculator pump content set to E83 vs E85 snd set the tank amount about 3 gallons less than the indicated amount to ensure I always have a bit more than E50 when filling up. I usually measure out to E53-E55. Its fine to have a few % more E50 for sure and I've tun as low as E35 when E85 fuel is not available during cross-country drives.
If you're not poking it WOT its fine as the ECU will retard the timing just fine. Now that said, if you're tuned hard to the limit, I wouldn't recommend it, but Winfield doesn’t do that unless you push for it specifically for racing only. Note I do my own tune so I have complete control.
