    Default Help finding a COS (Electronic Traction Control)

    I have been working with a known tuner to get my latest project running. It’s a 2002 Tahoe and I'm putting in a 408ci with a TVS2300 on top. I am trying to go with a 2 bar MAP and a COS from EFI Live. So far my tuner hasn't had any luck finding an OS to work. I don't know if it is because of the ETC or the drive by wire but the tunes he has been sending me to try have zero throttle response. The throttle body doesn’t open at all. Any help?
    The OS I’m running now is: 12216125
    Calibration: 12212431
    PCM Service Number:12200411
