    Fuel Trim Cell 22

    I've read that you are only supposed to be in cell 22 at WOT. On both logs this morning, it's in cell 22 anywhere from 36% to 90% throttle. It's a total of 25 of the 10000.

    The car was previously tuned with LS1 Edit. Heads, cam, intake, ported maf & TB Etc..

    What gives?

    Thanks

    I have the same issue now that my turbo is on the truck. I think it is actually PE mode, not just WOT? But then again, I have a truck so there is no telling.

    Anyone know where there is a definitive listing of all the FTC's? I'd really like to know what each one is for.

    Forgive me, i'm new:

    How do you find a specific fuel trim cell (ie. cell 22 or cell 16-19)? I have done some logging but I guess I don't understand where this "specific" fuel cell data is located.

    thanks

    This is how it works. Cell 22 is for WOT only yes, but only to a certain point. You will find that cell 15 is for WOT also, but you only hit cell 15 when you are at WOT and 100% engine load. Thats the true WOT cell. Hope this helps.
