    Default COS5 questions

    So far I've worked on AutoVE, trying to hit all the cells.


    Today I decided to try AutoMAF, and the truck runs a lot better.......does this mean my VE tables are that far out?


    Does it matter how long you run it, setup for autoMAF? (Have a 3 hr drive coming up)


    When I'm done with AutoVE and AutoMAf, I should change the cells in B3647 back to 1 from 1.01?

    Do I leave the MAF failed? Is that CLSD? Semi-closedloop?

    Yes.

    20 minutes should be sufficient as long as you're smooth/progressive on throttle.

    Yes, back to 1.00.

    You can run the CLMAF (full closed loop with MAF).

    lol---back to AutoVE.


    If I put the B3647 cells back to 1.00 and leave the MAF @ 0 rpm or 400 rpm, that is CLMAF?

    That would be OL pure MAF

    [ SOL = semi open loop which occurs only during OL; pure MAF = MAF only with no VE ]

    More info, see post #4: Summary-Notes
