I was wondering does the knock sensor suppose to go up on my PFC when I step on the gas pedal? Thx.

 

no, generally the value of knock will decrease when you slam pedal down. it make fluctuate a bit for throttle transition, but hten settle down quite a bit.

 

Yes it will. However, it's use is for reference only. Don't be alarmed that the bar is maxing out on yor monitor. That should be normal. On a good pull, my sensors show a max of around 135 or so. What you want to look for are spikes in the reading, those are bad. You can also put the monitor on graph mode to see if there are any spikes in your knock reading. I hope this helps.

 

Thx KZ and evel.
