Changing the VIN in pcm to pass OBDII test in swap vehicle?
I have been thinking about doing a semi daily driver/family car type build using an LS1/6 swap in a newer Lexus IS250/350. I know the "swap" is possible the only question I have is can I change the VIN in the LS pcm to match the VIN of the car I put the engine in, only to allow inspection. I do have annual OBDII inspections where I live and I am familiar with HPTuners. I do all my own tuning I just am not sure you can put just "any" vin you want in the PCM????

My engine and PCM were swapped over from a 00 Z/28, when i look in the computer there is no VIN listed at all. Did someone erase it? Was it maybe tuned that way? With there not being power to it for 18 months was it lost? Can the vin of the new car be added when i send out for a mail order tune? Thanks

The VIN is programmed into the PCM so it will not erase or reset even with the pcm being unhooked from power. The VIN can be deleted or changed so it is possible that is deleted but I doubt someone went through the trouble to delete it. What are you using to look for the VIN, HP Tuners, EFI Live, Tech II?

Can a Tech II tool change the VIN? We just did a 98 to 99+ PCM swap in my Camaro. My car is being tuned tomorrow, but I also need it to pass Texas Emissions later this week.
