what happens at ~3500rpm? knock

my car shows a knock peak at this rpm regardless of the boost. i can smoothly go up the rpms in vacuum, or go wot from 2000rpm and it shows this peak. it goes to about 70 knock.

drivetrain?

thats really a low number in my limited experience with knock sensors, there are people who have as high as 150+.

theres really no way to have knock to 0 as engines make enough noise that the sensor picks it up as knock.

you'd best post this in the tuning section

well my car keeps average of 25 knock under boost... so 70 is almost triple and i think it might be significant... just want to be safe.
