Default How many knock counts is normal?

Trying to see if this is an issue or not. I got a total of 8 kcounts in cylinder 2. I was checking on my flash pro app as I was driving.
These knocks didn't happen while the car was moving but rather when the car was stopped and when it was taking off. The first 4 came after I revved to 4k at the light to see if it would cause knock. The next ones happened when I was taking off in first gear. Is this normal? Car runs great and there aren't any CEL's.

Normal. Those were most likely caused by something external to the motor making the knock sensor think it was hearing knock.

Could be phantom knock as the other guy stated. Keep monitoring it and if it is constantly knocking at the same point then you might want look into it more. Do you get any when you are full WOT? Also what tune are you running?
