How do i find out the correct factory settings for my gm ecu when enabling flex fuel sensor?

Can you give us a little more info on what model car you're dealing with and what PCM it has?

Sorry for the slow reply. I'll try and find you a stock flex fuel calibration that you can do a compare with and swap across the relevant tables to get you started.

Hi Jeff, I've attached a flex fuel calibration for you to take a look at. You can do a compare to your stock file and copy across the relevant flex fuel tables.
