    Are the 1998 and the 2002 GTP PCM exactly the same? Direct swap out?

    You have to have the VIN programmed into the new PCM. But for the most part the tables and such inside the PCM are the same. And the PCM connections are the same on the PCM.

    I have an 02 GTP, but run a 01 file on my PCM. I have ran a 98 as well. There are some different tables in there, but my car didnt complain at all .

    97's are '97's only. '03's are '03's only. '98-'02 PCM's are all compatable.
