See this PaulW post from another forum :)

Modules can only accept coding which is meaningful to their year, and different year modules can have different coding. Different codings were used in different markets, and some modules are simply coded for different countries while others have different flash contents and will behave differently with the same coding, unless reflashed. All of the transmissions used are essentially the same, though with a different diff ratio in S8s, and with newer/updated and stronger parts developed over the years. Different shift behavior was programmed in for different markets at different times. It seems like the modules can be swapped pretty freely, though. (edit: though A8 PCMs want to be paired with A8 TCMs, and S8... you get the idea)

I have re-coded 1997 and 1998 modules to their euro settings, which works fine. It makes a noticeable difference in the 1997, but a massive one in the 1998...
