I am doing a engine swap, Ls1 into a porsche 944. This is a california swap so the PCM VIN is very important to how I can deal with emmissions.

I already have had the PCM sent out and tuned for my requirement. However, the unit came back with a VIN from a 2000 Camaro. As I am in California, I would prefer this to have a VIN from a 2002 F-Body. This is so I can get rid of the EGR stuff mostly.

The question is this; can any tuner that I send this to reprogram the VIN?

A tuner with EFI Live can change the VIN or someone with HP Tuners can tune the whole tune to a 2002.

Anyone should be able to change it. Those with multiple types of software can put in any vin you want basically. ;)

Great. So if i pick up a second hand HP Tuners with credits for at least one car, I can do this myself?

I only use HPT and EFI but I have run into problems when I changed the VIN with EFI and it didnt match the OS and I would get a VIN/OS mis match or something like that with HPT. I dont think you can change the VIN to a 2002 with a 2002 OS with HPT but I could be wrong.

Hptuners uses vin numbers for licensing. Because of that it's quit restrictive in allowing vin changes. EFI live doesn't use VIN's just the serial number of the PCM itself. Because of this you can change it to what ever you like. So if looking for tuning software I'd give hptuners a miss and go for EFI.
