that was my understanding and why I don’t have it. I have one e85 gas station 20 minutes away so it wouldn’t make sense since I’d run 91 90% of the time. I received info you couldn’t be hard on the car without e85 in it.

I heard that some of the m157 don't adapt quickly enough to be able to run 93 octane on the ethanol tunes. Has Eurocharged told anyone recently that the tunes are flex-capable? Maybe it varies depending on the level of the ethanol tune (e30, e47, e85, etc.).
I wouldn't risk my engine on assuming that the car sees heavy knock and will adjust timing down quickly enough. It takes less than 5 minutes to swap tunes with the MyGenius, so that is what I would do if I wanted/needed to run 93 octane but had an e30 tune on the car.
There are many people running the tunes, and many people logging with HPTuners ... surely someone has logged what happens when they run 93 octane with the e30 tune and floor it.

Hmm, well HPTuners is cheap ... add the tune, fill it up with 91 octane, log it, and see what it shows?
