I have it my other logs too. I am thinking it is either exhaust rattle, or drive line vibration. Where are the knock sensors located?
On my second look at your data zap, First knock event looks to be caused by a lean AFR for start of WOT. Are you using the stock thermostat or an even flow 160*? Engine coolant temps are shooting up towards the end of the pull. This is some what normal but your curve is excessive. Since you are not running an excessively lean WOT lambda my guess is you either have an air bubble in your coolant system, low coolant system pressure(leaky cap), or an under performing thermostat. The excessive heat generation is my guess at the higher RPM knock. You can just keep looking for loose parts all tho those usually max out the knock sensor.

adding picture of what my 170* thermostat coolant temp does to compare to your logs.

I put the 170* in. Reische states in the instructions that "there are no bleeding/burping procedues required, as these modern vehicles degas themselves". I left the cap off for about 15 minutes after i started it up and made sure it was filled to the line. I mean, i guess it wouldn't hurt to try and burp it. Lund says my logs look good and my fueling is within 2-3% while rpm is increasing. Stock tunes aren't even that close in most cases. All in all i am quite happy, except for the thus far shitty fuel in my area. Gonna fill up with ethanol free 91 next. My car stock seemed to like it more than the 93.

Grab some octanium or Torco. Even if you use half a bottle it's a good way to ensure your getting at least 93 octane. It will remove gas as a variable in your equation.
