E85 tuning

[edcmat-l1]

I’m 9:1 compression and 10 psi of boost fellas. Right now…I’m 18 timing on pump gas. E85 is 24 degrees of timing. AFR is running at 12.3ish under boost. Which seems high to me. But it’s running well and no KR. And tuned by a well known tuner in the area. So I’m just trying to learn for myself a bit.

As long as your top rings gaps are big enough you can get by with that AFR/ignition timing tune up. It is a bit edgy.

You won't knock on E so can't judge off that. That is a bit lean. I would run .77-.79 EQ ratio. Safer and won't lose much if any power.
