False KR ? ok guys long story short, i did a 5.3/4l60e swap into a 87 gmc put a small cam 219/224 got it ve and maf tuned but i keep getting kr even with the timing stupid low. i suspect false knock but i double checked all my clearances are good, didnt mess with the knock sensors when i did the swap. ive pulled so much timing that its absolutely sluggish now getting frustraited please help me! i know i should be somewhere 20-22 but i was trying to reduce timing from the kr histogram table and it keeps making me pull more and more untill im in the negative and i know thats not right! lol timing2.hpt i didnt save my last log i can take another if needed.

ok guys i did some more research and read about burst knock giving a false knock. so i zero'd burst knock out, loaded my earlier timing curve in, and no knock retard, so does that mean somewhere im hitting i cant see? and ive read that burst knock is the pcms knock prediction, is this true, and if so can i leave this disabled???
