You guys with J&S, how does your readings compare the the commander display knock readings? I have tried a few different things, including a new knock sensor but my readings are kinda high, I have richened the mixture and retarded timing but it didn't really seem to make a difference. My readings are only high under no load, like crusing on the freeway, as soon as the boost comes on they drop. I also tried rapping on the engine with a hammer with the key on engine off and at idle to see if the display changes and it does nothing...
Thanks,
Cliff

 

The J&S does not show or give any knock reading or level.
It only displays when it is retarding and then only lights up some LEDs.

 

from my understanding high readings off WOT is normal, you shoudl only be concerned when at WOT. THe rest do not matter. I see readings sometime as high as 80, mostly about 65 just toling around.
