I have just tried the nlts valet cel on knok patch, and i have found that i have cel flash on highway driving: these hapens sometimes on fifth and sisxth gear at about 3000 to 4000 rpms when i accelerate, i did a long list of logs in 3, 4, 5 and 6 gears at wot and i just get as much 1 or 2 counts and not alwais, i tried to get the mencioned knok doing long logs but i did not fownd knok but it stil flashes the cel sometimes on 5 or 6 gears at low rpms on higway driving.

the knok threshold is over 120 load and 4 counts.

in my wot logs i have never seen more than 3 counts

any ideas or just normal and nothing to worry

by the way i have not started to tune my maps so they are stock

 

You hit too mucho boosto when you step on it at 3k rps in higher gears. Either downshift, or get it tuned out.

 

Exactly. More load on the engine and more boost at lower RPM. If the AFR is good then pull a little timing where the knock occurs.
