Thread: What exactly does ETC control?

  1. #1

    What exactly does ETC control?

    As the title states. That's the only thing I've left on in the tune for TC & wondering if its the culprit of my weird groan?

    My speculation is that it modulates the brakes?

    Electronic Throttle Control = ETC.

    Anything and everything related to the throttle body.

    Thanks.

    Are you aware of anything in TC that modulates braking?

    TC as in traction control or torque converter?

    Traction control/StabiliTrak could be kicking in and applying the brakes, seen in happen in some circumstances (not on a CTS-V, havent tuned one yet). Torque converter could groan if it's on its way out. Id look more at your rear end though, that's where Id imagine the groan is coming from.
