Help me see if my engine is knocking

Hi everyone I would like some help on determining if my engine is knocking. I am new to subaru and to tuning. I bought a tatrix cable to be able to log the car and in the future to do or get some tuning done. I am very interested in tuning but it is not something that i can rush into learning on my own especially when i dont know anyone that does it that can teach me. But can someone please take a look at my log to help me see if the engine is knocking. I understand i may be logging to much so if i need to log less or log something more specific please let me know so that i can go log again and post it up here for someone to help me.

PS: In order for me to upload onto here it says i must have it in a txt format but those are a PITA to read so if you would like to be able to view it in excel change the file from .txt to .csv (Im sure all you tuners already know this but just putting it here incase)

Thanks everyone.

Try doing a log in 3rd gear from 2000-6000. That will make things easier to read rather than sorting through a bunch of useless stuff.Also here is a list of things to log:

Ya its tough learning but I wanna be able to do it so I will learn and read and get as much help from whoever I can.

Anyways I said I would do logs tomorrow but took a quick run and took them now i did 2 logs from 2000 to 6000 and then one log i had to cut short but will attached it anyways.

There may be a few things that did not need logged such as engine load i was not sure what one was wanted from that link that you sent me.

Here ya go thank you so much again

No knock, the other logs are just as clean.

Ran a quick log for you on Airboy as well since you appear to have a stock 2008 WRX. This is based on your elevation where you are, yesterday's weather data, and using 2008 WRX weight and 3rd gear data. If you used a different gear then this dyno is wrong. Power is at the wheels, and for airboy this isn't a bad number for a stock 2008.

Chris knows his junk.... From what he did, I can see everything now.

Only thing I see interesting is the PSI column, what is that logged in ? It's not KPA or BAR... and not PSI.

WTH is it? lol
