I've seen some pictures where it looks like there are only 2 yellow wires coming out of the harness on the drivers side near the head. Others "including mine" have two pairs "black and yellow" coming out of the harness. Is there a difference or am I just seeing things? Trying to track down possible false knock and I'm not sure if this harness goes to both knock sensors or if I have another harness and wires on the passenger side of the engine that I need to look at.
Thanks,
Scott

Thank you, I did see that. I'm confident there are 2 knock sensors, one for each bank. Just not sure on the wiring. That shows a single knock sensor with 4 wires. Not sure if that means the 4 wires I see on the drivers side harness is for a single sensor or if its actually 2 wires per sensor and the harness has both sensors on it. I covered the wires, did the whole zip tie deal and still have what could be false knock so I'm trying to figure out if I need to be looking for another harness or not. I'm sure AJP will get back to me via email while we are tuning for next steps but I am just trying to get out ahead of him and try to fix the issue if it is physical.
Thanks,

Each bank has a single sensor, but they are wired together in the same harness (#9 below). There are 2 small wires bundled together that go to each sensor.

If you use Torque, you can log the raw data from each sensor independently. That might help determine if your KR is related to a chafing wire. In my case, the raw KS numbers are fairly even.
KS Raw
PID: 220403 (KS1) 220404 (KS2)
Max: 32768.0
Min: 0.0
Equation: ((A*256)+B)
Knock Correction
PID: 2203ec
Unit: deg
Max: 8.0
Min: -5.0
Equation: ((signed(A)*256)+B)/512
Excellent, that is what I was hoping for. And thank you for the info about Torque being able to see each individually. I assume if there is a major discrepancy between the two that I could have a bad sensor or wires/harness. I have torque and a bluetooth OBD2 reader, just need to get it all configured again.
Thanks,

Never added custom PID's before but I assume:
Equation: (((signed(A)*256)+B)/512
Should be
Equation: (((signed(A)*256)+B)/512) correct?
That should also work, but I just included an extra left parenthesis. Should be:
((signed(A)*256)+B)/512
Being a software engineer, you'd think I could type, but sadly, no...
