Thread: AFM/DoD controls?

  1. #1

    AFM/DoD controls?

    Im messing around with my new 14 silverado and i wanted to start playing around with the AFM controls just to see what i could make it do.

    I see no reason that with some cam angle work that the truck couldn't maintain 70 down the highway over all but the steepest hills.

    I wanted to see if i could get the truck to idle in V4...

    MIN RPM per gear set to 0
    AFM Enable TPS P/N set to 0
    AFM Min VSS set to 0
    AFM Min VSS Hyst set to 0

    and nothing....

    am i missing something? or are the needed tables just yet to "discovered"?

    any one ever tried this with any luck?

    let us know how it goes. we just disable it entirely.

    i see no real reason to kill it.

    opening up the rang thus far, along with cam angle changes, has the barge rolling along at 70-75mph in V4 mode.

    idling in V4 would be trick. damn the NVH impact, lets see if itll do it....

    no luck so far.

    There is no way it could idle smooth at 600-800 rpms on 4 cylinders.

    The hot idle for 8 cylinders is already set low at like 525-550.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
