    cruise control not working

    Anybody know all the parameters that control the cruise control in a 6.4? Did a single turbo swap and lost my cruise control??

    Nothing. Truck is like it was before except cruise doesn't come on.

    I am being told that it is because the VGT is gone. There is a way to tune it to work. Anybody know? I am seeing online that a few shops figured it out but they are not around anymore..

    I have tried enabled and disabled. Trying it enabled with zero'd out parameters this weekend. Kem Performance supposedly figured this out but he hasn't been in business since 2019.

    I wonder if it?s a communication issue as I believe the vgt controller is on a network, I?ll look at some diagrams when I get back into the shop
