51% ethanol on pump question

[dn1984]

yeah I just tried adding e85 for the first time. I have seen folks talk about doing e20-e30, but I didn’t want to try that initially. Was thinking of only going up to e20.

question: how long have you been running the e30 blend?

i'm on my third tank tank so not too much. picked up about 2mph trap speed using the onboard 1/4 mile timer too

Better to go full flex tune to get the most out of it and so that AFR is correct to prevent any issues.

AFR is exactly why I tried to keep mine below e15.

I have no doubt a tune is better but this may be my poor man’s recipe for a little more octane

from what i've read the gen3 coyote adjusts up to E30
