Any dealer or shop with access to a tech 2 or mongoose should be able to do that pretty easily.

as long as the vcm id number in your pcm doesn't change you'll be fine, when you license your vcm you aren't licensing your vin number, you are licensing the actual vcm itself. If someone flashes in some random file with a different vcm id number our software won't recognize it as being one you have a license for and will ask you to relicense the new vcm id number and is the reason I recommended tech 2 or mongoose as they won't affect the vcm id number.

I was always under the impression that it required special software to change the VCM serial number, if it was easy to change wouldn't everybody be out making all the VCM serial numbers the same and cheating everybody's license scheme? I know when you buy a dual flash setup, they match the VCM numbers in both chips and can even make it the same as the original chip, but I thought they need a special programing set up to do it.

ok so if a write entire was performed when they wrote the 99 tune to my computer did it change the vcm id

Bill's description of an ID number is not the serial number of the PCM. The serial number doesn't change unless you hard code it with an EEPROM burner which you haven't. Go see a tuner with EFI LIVE as they can flash in any OS/VIN combo they like being that their licensing isn't locked to VIN/OS combos.

PS Why was my last post deleted? This isn't the HPT Forum so why can't facts about the HPT licensing system be shared here.

Just to add to this thread. If you have a custom/enhanced OS then a Tech2 won't be able to connect to the PCM.

Thats only a HPT limitation as in their infinite wisdom they decided to change the seed key when you implement a custom OS. For an EFI LIVE COS you can full flash over it if required with any other tuning suite or Tech II.
