The Engine Control Unit (ECU) from a '95 Civic is going to be different than the ECY from a '92 Integra. The plugs will be essentially the same but the program inside it will be different and there are certain connectors which are not shared. Each engine has its own unique ECU and if the motor was sold across OBD generations (from say, '94 to '01 like the 3rd-gen teg) there will be both an OBD1 and OBD2 ECU for that motor depending on which year the car it came from is.

That's an unofficial designation.
OBD1 and OBD2 are actual systems mandated by the US DOT.
Honda changed their ECUs over to a different style in the '01 Civic, RSX, etc. These still conform to the OBD2 spec but because they are different from the first generation of Honda OBD2 ECUs they're sometimes called OBD2.5 just for the sake of clarification.
