    Then change your high and low count thresholds from 400 to 1.

    Then...

    You want the DFCO section further to the right, where you can alter rpm and/or ect to turn off dfco. The one you are talking about is for rev limiting, not dfco.

    A log would help. Does it still use the FSCM, or is it a return-style system now? FWIW, I noticed that you are asking for 475kPa in the ECM, but the FSCM is still set to 450kPa.

    I believe it has to do with the algorithm used to trigger a knock sensor fault code. Used to be 12 or something on older stuff, then GM changed the calculation and it's 2 or 3 on newer stuff.

    Thanks for the in-depth explanation. I'll give the 7 and 1 settings a try and see if it works. If so, I might go ahead and pick up a 30-0310 and give you a shout. Many thanks!
