I am verifying through my tuner on if the car will see more timing on the better corn. In theory since I am flex I would think the tables would adjust based on the higher ethanol content, but I am not sure.
I can’t speak for the hellcats but in the coyotes on a flex tune it normally is full timing by 70% ethanol

Not mine, when mine was tuned the first time I picked up 12hp and 6lb tq between 70% and 76%. So between 70% and 85% it should p/u in the neighborhood of 25-30whp and 18lbs tq
You're not getting true 85% from a pump. Was there an increase in timing between the 70% and 76% runs? On an 800hp vehicle, a 12hp gain or loss could have been a multitude of factors that have nothing to do with a 6% increase in ethanol content...

Per my tuner and I think Hellpig could verify as we are running the same flex fuel tune. Our PCM's adjust the timing per the ethanol content.
He told me I will definitely feel the difference when I get true E85 or close to it. I'm still educating myself on corn as this is the first time I have had it.

Sounds like they get pretty aggressive. Out of the pumps here in IL, the most you're gonna see is right around 80%. I think the pumps even say 81% is max ethanol content. The highest I've ever seen my tube tester was right around 90%, but remember they read high.

Correct me if I'm wrong. But I can throw in some ignite to bump it up as well if I wanna throw a kill tune in and chase a number or grudge race.
I'd need a quick refresher, but I was able to read my logs when I had my 08 Jeep SRT with the blower and knew how to safely adjust my tune. I'm planning on hitting the track soon with my tuner and with his guidance making some revisions to my tune on the fly. Not sure I could get my 60' down enough with my 22's. But I'm gonna try like hell to run a sub 10.5 on this set up on 22's.
