Any suggestions what i should do next then? I guess I will look at hardware once more. Then put everything back to stock and check to see if I get that error code. thanks for your help.Datalog looks good! Looks like air/fuel ratio is between .850-.900 at WOT and timing peak is 26 degrees. It's pulling timing, but not via the knock sensors. You went to 7000 RPM a few times there, and only once did the knock sensors pull timing, and only after the 2nd shift, so I imagine 3rd gear. The timing is low, and it's more than likely because of how hot it is. Nobody is able to keep their intake air temps down this time of year.
