Curious which car you have that your MultiMap Stage2+ shows a 91 Octane choice? Mine does not.

However I have run MM St2 with E85 in 91 & 93 slots and could not feel any difference. Which makes sense because static 91 & 93 tunes when they are running and fueled perfectly only have like a 2% difference.

From what I've seen, no. I thought it may've, but as long as the flex fuel kit is working correctly it shouldn't matter.

B58 Gen 1, I did some testing to see if there were some timing corrections since it got removed for that last time, the flexfuel kit helped with those corrections as I only use 91+10% ethanol, car runs pretty good.

I tried ACN91 vs 91 on multimap, got additional .5deg of timing. Gen2 B58 with flex fuel sensor.

I'd imagine you did, but don't forget to flash the new map. I had to delete my current flash off the page and grab another one from the OTS map page to have the updated octanes.

I just corresponded with ProtuningFreaks and they said that, if you have a flex fuel sensor, the map slot 91 vs 93 doesn't even matter

It's most likely due to the 10% ethanol in the 91 fuel.

I ran the logs by them and the car runs great.
