Hi,
I replaced my faulty PCM in my 2003 wagon with a 2005 Fairmont Ghia PCM. Everything worked great using PATS. Only problem now is that the speedo reads wrong. Speedo says 40kph but actually doing 60kph. Have read on this forum that need to update PCM VID blocks? The PCM doesnt show up on the configuration tab in Forscan. Have paid version and using VGATE VLINKER FS USB OBD2 ADAPTER from OBD2 Aust.
