Vin Number Change LML

[Biodiesel66]

Before I go to the trouble and get a spare LML ECM and swap it out.

I know about scanning and BBL the LML is no problem.

What about changing the vin number and reading GPCM?

I was able to read the the GPCM from the LML ECM and have a 1K file, have no idea if the file is valid and if it will work using the V2 to flash to another LML ECM?

No idea sorry, it's never been tested, any of that.
The VIN shouldn't be an issue, but I'm not sure the GPCM data would be 'exactly' the same as the LMM.
Unfortunately the LML ECM's we have here aren't pulled from trucks (they were new) so the injector data will be blank.
