1999 ECU swap

Hey guys, does anyone know what exactly the part numbers mean on the stock ECU's, EX: The "BP4W ...." tag that is on the front cover of the ECU, are there certain one's that are better than others that came from the factory? Can you interchange an automatic car ECU with a 5 speed? or newer model ECU (2001 +) on a 99 car. or are the connectors different?
