LS1 Flash Tool Released

[1project2many]

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.

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.

I dont think there is a way to get the pcm service number from the 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.

so to properly identify a 9354896 pcm I will need to create a list of OEM service numbers to OSID.

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.

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.
