I just want to point out that in my LIMITED EXPERIENCE WITH MY CAR, the OEM knock sensor is working VERY well for me.

I have a PFC....with stock head, I would see typical knock counts of 10-12 or less when getting on it.

Occasinally (due to piston slap I think) at very high RPM when hitting fuel cut or in between hard shifts, I would see it spike to like 50 or 60 for a SPLIT second.


After installing my bigger cams and stiffer valve springs, I now see it go up to around 20 on normal driving at high RPM....this is normal.

ONE time, I overboosted and actually heard the engine knock (only a little bit for a second).

Sure enough, the knock sensor read in the 70s.

That being said, I believe MY knock sensor (OEM) on MY setup is working just fine. I feel that I have driven the car enough that I know that knock of 20 or less is just drivetrain noise.
