Buzz: thanks for the detailed level of testing, much appreciated. I dont think there is a way to get the pcm service number from the pcm, so to properly identify a 9354896 pcm I will need to create a list of OEM service numbers to OSID. The actual pcms arnt any different, and the operating systems are interchangeable. Especially as I start supporting 1mb pcms I'll need to do this.
1project2many: It will attempt to communicate with any VPW pcm. There is nothing different about the 12200411 and 9354896 pcms distributed in different parts of the world, and I am in australia developing against aussie vehicles. Even unsupported VPW pcms should display info, and depending how similar to the '0411 they are they might read or might not. I have been advised that LB7 duramax OSID 15189044 and 3904405 DO read. Possibly others but I will need OSIDs to whitelist them. This was just a fluke though, I dont have intention to support write on those yet as I have never even seen one. Maybe one day, though.
good to see your here :)
Agreed ... EFILive and HPT don't list the PCM Service Number for this very reason. TC does, but via an extensive look up table - which is linked to the OS used, but not to any hardware detected - a 2002 OS flashed into a 09354896 PCM will be inaccurately displayed as a 12200411 PCM.
My 2 cents ... simply remove this displayed parameter from your software (like EFILive and HPT have opted to do).
Very good. I'll have to get it wired up and see what happens. It's not even listed as a GM PCM in North America but it's definitely a Delco controller. You guys might have a similar controller in the Daewoo J150 w/2.0.1project2many: It will attempt to communicate with any VPW pcm.

The "service number" is the current part number and based on GM's parts history it's subject to change. I'd be surprised if that data's included in the pcm.I dont think there is a way to get the pcm service number from the pcm
The US EPA and some states use a list of CALID, Application, and PCM Service Number to determine whether or not the vehicle has been tampered with (under EPA definition). If you can find the data, you'll have a very thorough list to work with.so to properly identify a 9354896 pcm I will need to create a list of OEM service numbers to OSID.

A tool that would allow you to edit the CVNs back to stock would be awesome.
If you mean something that can fudge the tune to make the data match the original checksum, then sorry no. A flash tool should not edit the tune, only read and write what you supply.
v1.04 has been released. A few fixes for LB7 duramax.
