Does same bike (year and model) bikes have different controlunits?

Hello,
I bought a electric harness from a guy in a different country where the engin broke.
I now noticed that the Controller unit is different between my boke and the one I bought the wire harness from, it does not have the same connector as on my original harness.

My unit is called: 8000H0596 ECU181-A002 and the guy from whom I bought the wire harness has one called 8000B0654 ECO181-A001.

Will the ECU181-A001 work with my bike and my fuel injector or is the control unit mapped to the fuel injector so if I buy the controller it will not fit my bike?

Please advice, I have bit of panic
