    3 bar with flex fuel sensor

    looking for a os that will have flex fuel sensor and be able to upgrade to 3 bar. I found one from 02 suburban went to add 3 bar and it didn't have the option

    If your trying to stay with a 0411 pcm there isn't one. 12216125 is the only flex fuel o/s for the 0411 and it is only 2 bar. If you want 3 bar and flex fuel you have to look into another pcm.

    I would also be interested in that information. Getting ready to need the exact same thing.


    Would a P59 controller work for this idea. With say a 04 corvette as the base?

    I flashed a 2003 Silverado (P59) that had flex tables in the OS and would take a 3 bar OS. The owner didn't have a flex sensor on the truck, but all the tables were there. Factory OS 12579405.
    I build stuff...
