I have consistent Knock On Throttle. The PFC Heat Light starts blinking. I've narrowed it down to the following :

1. Consistently starts knocking at 2500RPM upto 3500RPM's.
2. Knock according to the datalogit is low 30's to high 70's.
3. I've reduced warning thresh to 20 and gone around with a mallet tapping various parts including drivetrain but the problem still persists.
4. I;ve replaced or rechecked everything from injectors, coils, ignitor but everything seems to be within spec.

A couple of questions:

What are dangerous knock levels?
Could a faulty oil pump cause knock?

My relevant Mods
PFC, GT35/40,OBX FPR, Hi-Flow Fuel Pump,Straight 3 inch exhaust Piping with apexi cat back.

I appreciate any input on this.

Regards,

Dave

 

Knock in the high 70s wouldn't normally be that troublesome. Have you checked the condition of all the sensors using the Commander?

 

From what I remember the answer was to my knock question :

30 is no more dangerous than 70, as long as it's constant, what you want to look out for is sudden increases in a nominal level.... (Spikes)
