Question knock retard at just 10-12% throttle???

I just got Autotap, v 2.04 and went out logging for a few.

I've been having some problems with the car, and I've had it logged once already seeing UP TO 6* of knock retard.

Tonight, I see that I start getting knock retard anytime I go above 10-12% throttle. It didn't matter what speed the vehicle was travelling at, didn't matter what RPM the engine was running at, what gear, or anything else that I can tell. Just anytime I went over 10-12% TPS, the knock retard kicked in.

Can anyone give me some pointers on where to start to look to figure out what the deal is?

Mods are listed below, in my signature.

I can email an Excel file of the log if you want to see it for yourself.

Check if your knock sensor is good.
