Sorry in advance for bumping an old thread but did anyone find a solution to this? I have the same issue and my ignition map ended up looking like it had a huge hole in it to get it to not knock and I verified I have good compression. About to switch everything back to stock because I don't want the ECU pulling timing from false knock. If anyone found a long term solution to this, please share it.

I solved my ghost knock today and wanted to post back. Either removing my spare tire in the trunk, an oil change, a valve adjustment or tightening down my battery heat shield (which was really loose) and bending my battery heat-shield TOWARDS the motor (it gets bent away during valve adjustments to get cylinder 4 exhaust side by accident and I'm sure it happens to others. Prior to today, i was getting really high ghost knock counts, almost 300 in 30 minutes. These were the things I changed and just drove it hard for 30 minutes with not even one ghost knock. Just wanted to post back my findings. Take care.
