Silverado in EUROPE. Please help VATS delete

[Europeuser]

Hello. I'm new here and I'm asking for help. Could someone help me disable VATS in a Silverado LB7 Duramax E54? I read the contents using PCMHammer, but I can't find the xdf file that defines the sections. I'm from Poland, and it's not a common car here. I'm asking for help. We have a car in which the engine and transmission computers were stolen. We bought a second ECU, but despite trying to adapt the original key (3 x 10 minutes), the ECU won't pair. The only solution, I believe, is to disable VATS.

Thank you in advance for your help.

I have not done vats on that ecm.. given that there are 2 files below. One with vats turned off and the other with vats AND the theft dtc's turned off.. Someone else may chime in with more knowledge/experience with different files/info..

Thank you very much. I'll test the files right away and let you know if it helped.


I have another question. Should I change the VIN number or does it not matter?

[Europeuser]

Something went wrong. When I tried to save the file to the ECU, I got an error and was told to post a debug log on the forum. After that, I tried reading it and the file partially read, but I couldn't write anything because it said "unable to erase flash."

I do not know, you can't even write the original back?
Is this with a bench harness or in vehicle?
Battery voltage looks ok, but is it a walwart power supply? car battery? etc?

I apologize for not providing enough information. I have everything connected on the bench. The wiring harness is correct and the power supply is a high-quality laboratory one. Yesterday I performed a full readout without any problems, but when I tried to write it today, I got a message that the data could not be erased. "CODE:01" has been displayed. Since then, the ECU has been unable to communicate properly....
If I desolder the 28F400 memory, can I directly upload the contents I read yesterday? Is it normal for the E54 to have an empty section between 3B00 and 3FF00?

Dont use pcm hammer 2 preview. That is a developer version with known problems. Use the official v021. Also program on the bench and check your power supply is of good quality. In car can work but it is not worth the risk and can be the source of problems. Having said that, note that LB7 is E54 and not supported in 021.
