ECU needs to be matched to car? V70-XC70 2004

I have a ECU (engine compartment mounted) from a working same model car. It is the same part number etc as mine. Mine is a 2004 V70, M56 trans and 2.4 normally aspirated.

When I swap in the spare ECU the car cranks but won't start.

Do I have to get the ECU matched to my car? If I do programme it is the programming in the ECU or the car? Meaning can only one ECU be matched to the car at a time?
