    Default LS3 swap knock sensor functionality

    A friend of mine swapped a forged LS3 with ported heads and a G6X3 (car SCREAMS now...very very nice combo) into his 2000 Trans Am. He's got the knock sensors plugged in with a conversion harness, and they appear to be talking, but I never see ANY knock retard at all...I don't think it's possible since I'm still just beginning to dial his cars tune in.

    I searched and found a few posts saying to make them more sensitive (lower the values in the Knock Sensor Level tables I think)...but should I do anything with the Global Gain table?

    I lowered the values in the 2 level tables to ~80% of what they used to be, but still nothing.

    Have any of you guys gone through this...have any advice for me?
