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?
