The Unofficial "Ask a Stupid Question" Thread

I asked that recently as I needed a new ECM and was told that -P was a California code. My 97 came with -B, for what it's worth.
 
It is a calibration code, I know that much.
Is it for California maybe? And would that calibration code still run the same as the other one?
I know that my cars have 718-b codes in the door jamb.

Yes, it is CA related. However, if there's any  real difference, you'd only be able to ascertain if you could compare the code. IIRC, some people suggested that the CA tune had another warm-up strategy (?).

OK. the code on the doorjamb is the last factory tune applied to your eec by a dealer. IIRC, that's supposed to make the trans last longer. That code is irrelevant if you have an aftermarket tune.It gets overwritten.
