Undid the serpentine belt and knock still showed so that elminated all the accessories. Since then, I've done a MTX swap and nothing changed eliminating the ATX. Ran 91oct with stock tune and also a mix of 4 gallons 91 oct with 5 gallons 100 oct, once again nothing changed. Checked the timing belt idler and tensioner when I had to pull the cams to clearance the buckets, it all felt/sounded fine. Really have no idea why it was doing that. I'm hoping to finish my built motor by summer so we'll see if it shows knock on a whole new motor.
After trying all that, Tom just turned down the KS sensitivity in the tune, now I only show knock very rarely but 99.5% of the time, it shows flat line.
