Dirk suggested a new thread listing missing codes, and corrections to current codes, so that he can update the RPO decoder. Please only post codes that you have documentation on, along with the source if you can. For example, code 1AY isn't in the decoder, and while I know what it is, I don't have proof so I'll leave it to someone who does to give the code and description.

 

I verified about 6 of my Formula's RPO's, 2 from my Firebird, and a couple others that weren't in the rpo decoder but they're all on the harddrive of the computer at my apt

 

Well the decoder doesn't have R6P, it also lists V73 has a fixed antenna yet my printout from GM just says USA/CANADA.

 

Also keep in mind some RPO's mean different things different years, and on different cars. While there aren't many that this applies to, they do come up.
