    2001 Denali LQ4 drive by wire

    I am working on a motor swap, trying to get this thing running.
    the 6.0 was originally a drive by wire, we have installed a cabled TB.
    I have wired the pins into the PCM for the IAC and TPS
    what are the next steps?

    thanks for the help

    The next step is to check if you have a PCM capable of controlling the IAC for the DBC throttle body.
    The only way to know for sure is to open it and look for a specific component. Check this thread for more info:

    Next step is to find the correct stock tune file for your needs and start tuning.

    Which car is the engine into?

    all 01 pcms are capable of running a cable tb. go into your system/system options and change the 1 under etc to a 0 and you should be good to go.
