Hi team.

I have the following question.
Analyzing my car's engine logs, I see a knock of 8.0 at low load. For example, if I shift from 3rd to 4th at 2300k RPM, the knock increases for a moment. At high load, the knock doesn't increase; it stays at 0.79. I want to know what's happening. Maybe it's a false knock. I should clarify that the knock doesn't increase at all at high load. I'm sharing my log and tune details.

My car's specs:
- HPFP updated.
-CPE CAI
- ETS big intercooler.
-Downpipe anda catback 3in
- LTR7IX-11 spark plugs.
- Smoke vacuum test: Pass.

Thanks!

You may have an intake leak (I know you said you passed the smoke test but the logs show a different story), and once you fix that see if anything changes. Right now the combined fuel trims are around 12-16% and the very small boost time you had in this log shows that the leak may be before the turbo.

Thanks for replying. Today I'll disassemble the entire intake system before the turbo to make sure it's properly adjusted. I'll come back and post the results. Thanks
