Thread: Major TqMgt That I can't get rid of, is it possible the Closes throttle during Shift?

    Major TqMgt That I can't get rid of, is it possible the Closes throttle during Shift?

    So, after many rounds of trial and error I'm wondering if the BCM is closing the throttle during my first couple of shifts? When I turn the Traction Control Off it doesn't close the throttle. I can't be the only guy that has had this issue so I'm reaching out for some help...

    your fuel trims look really rich try dialing in your MAF and VVE tables a bit more that should help in general.

    All the torque restrictions in the trans are still enabled on the torque managemnt tab try disabling those


    ill keep looking thru it for TPS stuff

    Looking at your scan it seems under the torque source pid you are logging that its switches axle to trans L when it closes the throttle, which I believe is trans long term. I'm not sure where in the trans tune it sources this info in order for you to change it. Anyone else have a clue?
