hi

i got jrsced CTR with 3.2 pulley ,denso ik24, aem 3.5 map sensor and 750inj and i have one question
do the belt slippage has anything to do with knocks ?
cuz i got a mass knock counts after 6500rpm just after the belt slippage, nothing below 6500 and its run 100% perfect with no issues.

for example , today i got 68 knock count just after 6500rpm to redline, this happened after i pulled 10 degrees of boost coloms at 50 degrees. coz it was worse be4.
how can i solve this problem ?
thanks

try reducing the timing by 3-4 degrees and see if it goes away, if it does not, then it is just mechanical noise and can be ignored. You should aslo fix the belt slippage.
