M271 W211 ECU to M271 A209

Cheers guys. I own a 2005 manual A209 1.8 kompressor with 163 hp & i have an ECU from an 200 auto W211 200 kompressor facelift (184hp). I want to "upgrade" the hp via ECU swap. Both cars have the 1.8 m271 engine, have the same supercharger, same injectors but with the w211 virginised ecu in the w209 the car starts but will not accelerate more than 2500 rpm & has a ESP error that says the esp module does not recognize or sees the ECU. What can i do to make it work properly?
