What knock count should make me worry?
Thanks TB. Wow, cant believe Ive never noticed that function on message boards before. Anyways there it is.
all logs were done in sequence on a long flat road. Pulls in the logs are 3rd and 4th gear to redline.
I think log one looks alright, log two is so-so, but wtf happened to cause such a knock increase in log three?
Help is appreciated.

Looks to be a little lean. Add some fuel across the board (160+ load, +.2 or so in the map) and pull a degree of timing where the knock is ... 2 degrees if it's over 5. That 10 count at 7200 is a worrier ... address it first. Same with the 9 count at 7500 in log 2.
The big counts in log 3 are being triggered by the NLTS. I won't they they aren't real knock though. The answer is to tune the load curve referenced during the shift to minimize timing changes (within reason). Large jumps in timing can cause knock to register.

I know what youre saying to do but I have honestly no idea how to do that. Any chance I can send you a map to fiddle with or something? From what Ive heard youre a good tuner.
Of course if money is required I am totally ok with that

If you aren't comfortable with that, I can help you out. Send a PM ...

Read that link and understood as much as possible. Decided to followyour advice and knocked the timing advance down 1-2 pts in the 240-260 load area at 7k-8k rpms. Also added .2 to the fuel map everywhere from 160 on at 3k rpms+.
also should note I turned down the boost from 24 to 23.5ish.
These are my two latest logs after all the changes. Whaddya think?

you need to log load so your not guessing where to make your changes. Post up your a/f and timing map if you dont mind. So we can get an idea of where everything is supposed to be. What type of fuel are you running?
