you should post up a list of mods so we know what we're looking at. also post in CSV format from now on please and read here on what you should be logging. engine load's important. you should also put in flkc and knock sum.

looks like you have a good bit of knock though, even at partial throttle. i'd hate to see what you look like under WOT

Detected knock is caused by a few things:

 

• Insufficient fuel type (too low octane rating)
  
• Too lean mixture. (make sure that your MAF is clean before you take the logs for example)
  
• Something loose on the engine (or close to it) that the knock sensor picks up and think is knock. (The knock sensor is a microphone that listens for noise of certain kind)
  

And as stated in the link to RomRaider the following are useful parameters:

* Engine Load (2-byte)**

* Engine Speed

* Ignition Total Timing

* Intake Air Temperature (see note 1 below)

* Knock Sum (see note 2 below)

* Fine Learning Knock Correction

* Feedback Knock Correction

* Ignition Advance Multiplier

* Boost (see note 3 below)

* Mass Airflow

* Final Fueling Base (see note 4 below)

* Primary Wastegate Duty Cycle

* Target Boost

* Throttle Opening Angle

* Wideband O2 (see note 5 below)

And for repeated consistent testing use the same road part every time, preferably a long relatively straight uphill part since it will give you more time and therefore more samples.
