If I get a 96 P72 ECU, can I match it with any B18C1 engine 97-98?

The reason I'm getting a 96 P72, is because I have a 96 D16Y7 engine in my Civic, that system does not have a fuel tank pressure sensor, bypass solenoid valve or any other newer evap components. Those newer components hookup to the ECU. My car only has the 2 way valve and the charcoal canister. I found out the 96-97 B18C1s have the same components as my car does. Since the 96 ECU doesn't hookup to the newer evap components, I wouldn't be getting any CEL codes.
 
Would the 96-97 number be different? Because there aren't any evap components plugged into the ecu. 96-97 models don't have them.

EDIT: By being a different number I mean the last 3 digits (e.g. A03). These are the digits that I want to know which ones would be associated with a 96 or 97 GSR.
 
Yes, there is a EVAP system on all 94+ GSR's.

The ecu from 96-99 is the same. The last 3 digits just tell where the ecu is from (A##), if it's a auto or manual (#0#), and what the firmware revision is (##3)

So if you have a A03 is a USA model, manual trans, firmware revision 4
