How to test knock sensors
I had to relocate my knock sensors to the outside of the engine because I went to an ls2. I have never seen a single degree of knock retard and I am wondering if my sensors are even working. At the same time I also wonder if I was picking up some false knock before.
Is there anyway to test the sensors or simulate some knock? I am pretty sure they are enabled and all in the PCM.

I installed a TSP 418 in place of my LS6 and relocated the KS to the side of the block, and they didn't show any knock retard ever.
Go to the Knock Sensor Global Gain table and multiply the entire table by .9 at at time to increase the knock sensor sensitivity until spark knock is seen with sensible spark timing, then increase the table by 5%.
