    r42lts plugs in and new knock sensor they say tq is 14 so I did just under that so it is not too sensitive from what I was reading. Took it for a drive and still getting alot of these knock counts but no timing taken out. This computer/knock sensor is very sensitive it seems. Something else weather I start tunerpro before I start the truck or after I start it, I always have anywhere from 300-1000 knock to start with. is anyone else having this happen to them or how to stop it.

    On my test drive I had 2 places where it actually removed timing so I know I have to lower that area but what do I do for the knocks that do not remove timing. Would energy suspension motor and trans mounts cause this?

    if anyone could take a look at my configs and see if they see anything I have set wrong or pointers, that would be great.
    One thing I have 6 degrees of timing in the distributor and set in the chip so in the log it shows -6 of actual.
