    Default 2007 Chevy Suburban DOD/AFM Disable+ Tune

    Good morning
    The wife and I purchased a 07 Chevy Suburban with the 5.3l V8. I would like to put a stage 1 tune and disable DOD/AFM. I am able to use a EFI live tuner from our shop. I have never used efi live . how does this work. is there a way to purchase a a stage 1
    tune for my SUV ?
    or can I just download my SUV stock tune and adjust parameters, and disable DOD? On my other car when I purchased a tuner for it, it also came with 4 generic tunes from tuner manufacturer. does efi work same way?
    thank you in advance

    read the ECM and TCM tunes off your truck with the EFI Live and save them.
    You can adjust the parameters needed to get the results you want.

    is there a post or somewhere to learn or read which parameter needed to adjust on TCM, ECM? for now i want to turn off AFM/DOD . I am getting a S&B air intake however they are on B/O. planning to do full exhaust with headers. depending on how hard it is to remove pass header.

    Disabling DoD is not that difficult.

    Read ECM, save file, open file, scroll down to the DoD folder, adjust calibration values accordingly. Save file again, with a different name, license ECM, then cal flash ECM.

    Just for fun.. Here is a Script to run on a E38 ECM to disable DOD/AFM
    Save this file to this Location on your PC

    Documents\EFILive\V7.5\User Configuration\Scripts
    E38_DOD_AFM_Disable.txt



    Read your tune off the ECM and save it
    Open your tune
    Press CTRL+P to run a script
    Click open at the bottom left and find this file name to double click on it
    Bottom left click Run
    Click Close
    Save file with a new file name
    Cal-Flash the tune and your done
