I bought a 1998 ls1/t56 out of a Camaro. It did not come with a PCM. I looked at options to buy a 1998 PCM, but they are a bit harder to find. I read about swapping over to 1999+ PCM, but I have a few questions.

Besides resin the connector, what do I need to do? VATS? Program 1998 VIN into 1999 PCM?

Will there be any security features giving me a hard time? Etc

Also, please educate me on the AIR and EGR systems on the 1998 motor as far as the 1999+ PCM cares. I want to buy block off plates for these systems and I am not sure if the 1999+ will throw codes

Thank you for reading

Are you putting this engine in a 98 camaro? I would find a used 99-02 harness or better yet buy one from PSI. Get rid of the vats and emissions stuff in the tune.

Thanks for your reply.

No, I am not putting it in a Camaro. I am putting it into a 2000 BMW 323i.

Despite the LSx swap being so common, I can't seem to find much info about what all I need to do to make sure it works in a different chassis.

Funny enough, I strongly considered the 99+ PCM swap. The seller actually lost the PCM without realizing it, so I got home and realized I didn't have one. Buying a 99+ PCM and re-pinning my harness seemed like the perfect solution.

99+ PCMs seem very easy to buy - 10s of sellers on eBay have them ready and waiting to ship for $80, but the issue is they all want your VIN number to reprogram it. I guess I would give them the VIN on the motor, but they would know that's a 1998 VIN.
What now?

We sell 99+ pcm's stock or we can program them for your swap for additional, we don't need a vin.
