I am learning how to use tunerproRT and data logging and as I am trying to understand everything I noticed that while logging and driving I get lots of knock counts while idling (550-600 rpm) but nowhere else and I make lots of WOT passes so I want to know if my sensor is going bad or the noise it hears is something else cuz my timing is set at a perfect 0 degrees with the connector unplugged (1989 v1500 fulsize blazer 5.7 tbi headers and intake only).
What could it be?
