I've seen the option for virtual flex fuel in the ECM. I'm looking to use this to help with accidental misfueling with flex fuel.
How does the ECU determine the flex fuel virtually?

Don't use it, it's never super accurate and most people always disable it. Install a real sensor if you want to use flex fuel.

If you don't post your tune and logs when you have questions you aren't helping yourself.
It causes a lot of issues even in OEM applications.
