    Knock Retard Min/Max RPM

    C6 LS3 here with an A&A kit.

    I'm not sure what this means. See picture. knock retard.png

    To me it says - If knock occurs, it will only retard the timing while the engine is between 7900 and 8000 rpm.

    Just need this cleared up. When I was N/A, my car was tuned by a reputable guy (has dyno in garage and a 2000hp camaro). I just want to know if the knock sensor is active.

    Thanks.

    It would think so. Why not log it and see if timing is being pulled below 7900 RPM?

    I did. looks like the knock sensor is active because it was retarding the timing at some points. This is also how it is set up from the factory tune which is very confusing
