I use the symbol * to represent Degrees. Knock Retard and Timing are both read in Degrees. Mine could be a combination of both, like you stated. Knock Sensors and a PCM issue. This all of sudden happened a few months ago, but I never really cared about it because Cruise Timing isn't "detrimental" to an engine like WOT KR is. But it has gotten worse over time, and now when I'm cruising anywhere, my KR is pegged at 14.9* KR and the car is pulling all my timing, and causing me to average 14 MPG. And this can't keep going on, as the issue needs to get fixed since I'm wasting my money on fuel every 4 days. Averaging $40 every 3-4 days.
Your guess is as good as mine, at this point. Luckily, I do have a ZZP Canned tune for my car laying around in my garage. It's a **** tune as my LTFTs are -21 +/- while driving, but it might give me an idea if the KR is related to a bad PCM or not. I could try switching the PCM's and plugging my Knock Sensors back in, and seeing what it does.
Exactly. My only thought at this point is it's PCM related or possibly a combination of both a bad PCM in that regards and faulty Knock Sensor(s). Like I mentioned above ^ I do have a spare ZZP Canned Tune PCM in my garage I will switch out and see what the car does. Could also try putting my newer Denso o2 sensor back in as well.
