Technically you cant swap the serial numbers around on any bin file. I could be wrong there, but I dont think you can.

As far as the VIN goes... its not required to even be a value to do anything in any editor except probably HPT. I typically just leave it blank and use the PCM's VIN number when flashing. If I remember right, the VIN and SERIAL stored in the BIN file are just "bonus" bits of information, as they are installed seperate of the actual file when flashed.
