I've been playing with the "Power Enriched Fuel Multiplier vs RPM"

I've been lowering the AFR, then flashing, then driving around running a scann... Am I correct is assuming that if the Knock Retard is at 0.0 then I have no knock at all???

Any inputs as to what I should set this stuff to? What should I be looking for when I lower the AFR? What tells me that I have lowered it too much?

from what i understand, changing the AFR will make your O2's richer or leaner depend on which way you go. i think they are supposed to be between 8XX-900...check out this thread on ls1tuning.com might be helpfull

Ahh ok... so it's easy.... simply lower the PE value until you get a knock, then put it back to where it was before there was a knock. right?

more or less...worked for me a bit. if you are still getting traces of KR...then you might want to pull some timing from those areas as well.

Interesting. I have had some people mention MAF and MAP tables also. I'm kinda scared to mess with the timing though.

try reading over at ls1tuning.com...or hptuners.com and their forum. just takes a little research. more than anything what i found works is to start out small. 1-3% changes won't hurt anything if you do them incorrectly, well they shouldn't at least.
