Help with possible Knock issue

Spooler · 12-10-2023, 12:22 PM

Do you have a proper set of catch cans? If not, install those and see if it improves.

What you need to do is run this program on a set of logs covering the entire RPM range:

https://www.dropbox.com/s/ww0pvzp2a6...ilder.zip?dl=0

This program will reconstruct the knock threshold table from within the tune and will show if it has been tampered with directly. There are also other ways to disable or desensitize knock sensors, but based on the data you're posting, I think you're after determining the KS threshold table from within your tune.

In order to determine the factory table, we need to know your calibration ID. If you can post it, I can open the stock rom and post the stock KS threshold table for you to reference. You can then compare the generated table from your logs VS the oem table to see what kind of tampering has been applied.

Yes, he said he's not to sure if its real knock and to run octane booster to see if it changes.

I ordered his recommended boostane and waiting for it.

You must have Java installed. Search "download java" then simply drop your log files into the same folder as the .bat and .jar files, and double click the .bat file - the program will run and will produce a new KS table for you to review.

You can get the calibration id by using ecutek query ecu or using the bluetooth to check "ecu information"

I ran the program it created a new file called ks.map.new I attached it for review, thanks again.

I found this Cal ID - #Ecu 1 CALID: 1TH1B

it looks like you ran it on a narrow rpm range only , 1600 rpm to 6300 rpm - if you want a more accurate table you'll want to feed in as much data as possible for the widest range possible.

Where do I find the calibration ID ?
