Default 98 ej22 ecu to ej25 ecu

I searched and found nothing on this so I was wondering will a 98 2.5 rs ecu plug into my 98 2.2 harness? I just swapped in a 2.5 rs and figured it would run better on an ecu made for it.

It'll plug in and run. If your EJ22 didn't have an EGR system, you will get a CEL for it since the 98RS will look to operate it.
