Hello Ktuner's,
My name is Leo and have recently purchased the ktuner 1.2 for my accord. i noticed that i am getting high knock count after doing a factory base tune. not sure if this is mechanical or bad tune. I have re-timed and done a compression test to validate any timing issues. i have attached a datalog file , if any tuner with experience can review and give some insight it would greatly be appreciated. i am also willing to take my car to a tuner in so-cal for troubleshooting if the problem is not evident from the datalog itself. the datalog file is on neutral and i am getting a high knock count around the 2220-3000k rpm range.

Knock control is what to watch for an indication of overall health.

Factory base tune is factory, though, so I'm not sure how to offer you any advice.
