as far as I know, yes, the only difference is EEPROM. If you replace/reprogram EEPROM you can interchange these ECUs.
Oh, by the way, I think you'll need also a new immobiliser chip together with ECU.
Or, if you have CARPASS for your car, you can bind your old immo chip and new ECU.

The mapping on the 2.5 and 3ltr is very close  ;)

Yes, you get a little more fuelling at the top end but the 3ltr engine will run perfectly well on a 2.5 ecu  :)

I dropped a 3 ltr in my old 2.5 and ran it on the 2.5 ecu for about 6 months with no problems whatsoever  :y
