Holley efi and e85
It doesn't automatically tune anything, it's just using a single (or dual widebands) to correct your fueling if you have the ecu setup to that. It's basically closed loop with a wideband vs a narrow band like a stock GM pcm. You can run e85 with Holley right now, majority of the Holley cars I tune are running e85.

Ok so when are they going to incorporate the flex fuel sensor if at all, so it will correct accordingly using the sensor? I've read many places they were going to upgrade their systems to do so and that was almost 2 yrs ago!
