PCM Identification
From SaturnWiki
OBD2 is below but not typed out (and therefore not searchable).
All of the IDs are in decimal. So fire up your windows calculator and convert them to hexadecimal if you're comparing them to something such as an EFILive dump.
The PROMs across the models (SCx, SLx, SWx) do not change from anything I have seen. I believe this to be the same with the EEPROMs, but I am not sure. --Emailer33 19:59, 14 June 2006 (EDT)
