    Default Cobalt SS Supercharged KR question

    Guy I have been logging and dialing in my maf on this cobalt SS and I have ran across something that has me wondering.

    2007 Cobalt SS
    2.8 pulley, 60lb injectors, dual pass,LS4 TB, ZZP intake, ect.

    When logging I added the KR pid and along with it, it is showing KNKRET. I show very little KR during my log which does not stay, it zeros out right away but my KNKRET is showing a constant knock retard. Even at idle it is saying .7-.9 and varies with throttle. I do not hear any noticeable knock. Which pid in the P12 pcm should I be paying more attention to?

    The timing is based off of a base tune from a reputable company and seemed to have some pretty safe numbers in it. Just curious why one is differing from the other?????

    Here is the log and tune. I realized also I have a couple pids to many. I have fixed that since.
