If your Operating System is not listed (i.e.1999 and 2000 model years), you may use one of the 2001, 2002 Operating Systems. Unfortunately, it is not possible to upgrade your calibrations to the new Operating System. If you upgrade the PCM to a later year, you will need to re-tune your PCM for that Operating System.
You would upgrade to 12212156 = COS 020200xx

I use 12212516 and/or 02020005 and I like them both.
