Hellcat Knock Sensor #2 twice as high than #1

Hi everybody!

I have installed a build Engine from Demon Performance.
- 400CID
- cam
- Demon/Redeye SC
- 10% OD
- Longtubes

I am surprised that the 2nd knock sensor in the range of 4000 rpm to 4300 rpm displays absurdly high values.
some times twice that knock sensor #1
Because that i`ve set the Spark degrees very conservative in that Range.

The Long Tube or exhaust does not hit anything.

Is that because of the long tubes or is that normal that the #2 counts higher because of his Position?

Thanks!
Marc

Doesn't look too bad to me really. Built engines and cams be pretty noisy even when not spinnning blower really fast. Do you still have pretty much stock knock sensor thresholds in that tune? I see one spot in the cn dyno log where it starts pulling timing when not making hardly any noise. Misfires will set knock sensors off too so if less timing gets noisier that's something to consider.
