OFT E85: Set it and forget it?
 

I apologize if this question has already been asked, but I didn't see anything specific to E85... I know in the past it has been said you can pretty much run the OFT Stg1 or 2 91oct tunes and not worry about monitoring/tweaking (vs running 93oct tunes). My header back exhaust with OFT Stg2+ has been running with good trims and 1 IAM since around September. Would I be able to run the OFT Stg2 E85 tune (during Spring and Summer) without monitoring/tweaking?

Biggest issue with running E85 in usa is wide variation in ethanol content, some "E85" can be as low as 50% ethanol.


you would need to monitor afr and fuel trims or measure ethanol content
