Hondata

Hello. I have a 2007 Honda Civic Si 4dr (bone stock).
I bought the CARB Hondata Flashpro and uploaded the Stock Tuned Basemap [CARB] that came with it.
I datalogged my test drive, and I noticed some knocks occurring at high load / low RPM. Is this Normal? Or do I need to worry about it?
Also, can someone explain to me what K.Retard is? It seems to go up right before a Knock is registered.
I am using 93 Octane fuel in Texas.
Thank you very much.
Here is the data log for the first and second test drives

There are no adjustments that you can make using the CARB version. What modifications have been done to it?

The Car is Un-modified and completely stock...

Then I would not worry too much about it.

Thank you very much!
