I do only have 91 octane here so maybe its the gas but this knock is actually better than stock or when I had the AP still...... I have one of the cars that just seems to register knock quite a bit....
Thanks for the explanation. I'll try to adjust those things slightly and see where I am at.....
Thanks...

I don't know how much change you'll see with only 0.5-1.0 in the MAF table...but I don't want you go too crazy at first. Just to give you an idea, I started with -1 at 6,000 rpm to redline and now I'm at -10. My AFRs went from piking at high 9s low 10s (stock) to low 11s. I still get a little blip into the high 10s. I'm still working on it.

If you are running 91 octane, then definitely pull timing in the areas you have knock. try -1 degrees in those areas. I'm still struggling with timing...it seems to be a little more complicated than fuel. With timing stick with changes no greater than +/- 3. Start with +/- 0.5 and +/-1. Where you have knock pull timing -0.5 to -1.0 and see if you get a reduction in KR.

Tonight I'll post my current data log and current map just for reference...
