    Second set of eyes please

    Hi guys, was wondering if you could look over the two tunes I attached. Same car, just revised the VCT up top trying to eliminate the knock, though it may just be fuel quality. Anything you see please let me know, it runs and drives great would just like to have someone else look it over and offer suggestions. This is the first Coyote I have done.

    Nuked,
    Go to the Mapped point 22 borderline spark table and pull 3 degree's of timing at the bottom of the 7000 row. See if the knock goes away. If it goes away then it is fuel quality. If it stays then it is something else. JMO

    Just keep in mind that if you are seeing a -4 on the Knock retard. that is adding timing........If you see a 4 that is taking away timing. So you pay attention with the positive numbers in the KR sensor

    Thanks! I haven't really had a chance to test out higher RPM WOT yet, been trying to get the driveability down. Pretty happy with how it is so far, I noticed with the AC on that transitions from on throttle to off throttle are not nearly as smooth as with it off. Here is a log from today of just cruising around, I haven't touched the load/tq inverse tables at all, if someone could see if they seem ok I would appreciate it. Same goes for the MAF curve, I am running one from here and adjusted the transport delay some. Trims don't look too bad to me but again, a second set of eyes would be awesome. This is by far the most complicated PCM I have tuned, so trying to wrap my head around all of it.

    I've read on a few posts that negative numbers means knock and positive means adding? Now I'm confused lol

    Negative is adding timing, positive is knock. You want to see negative.
