So here's something I'm not sure is as intended, but I wanted to see if anyone has the same.

I installed one of Bend Calibrations Flex-Fuel kits awhile back in preparation for this release, so I loaded up the Stage 2 OTS CustomROM to make sure the fuel sensor read correctly. Great news, it was flawless (standard 10% ethanol content on 93 pump).

Satisfied that it worked, I converted my custom Cary tune for the anti-lag functionality, but out curiosity checked to see if the flex-fuel sensor still pulled up a reading. To my surprise it did.

I assumed that the flex-fuel function wouldn't be active on converted ROMs, so I'm not sure if this was by design and it's only reading but not functional, or if it was overlooked and is actually active.

Let's just say that the petrol-head in me is tempted to test the theory that flex-fuel is active on the converted map, but the realist in me doesn't believe its a good idea to test Murphy's Law.
