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.
