seem to recall you couldn't swap these ECUs - but not too sure
Pretty sure the ECU is tied to the BCM, so although you may be able to swap them, you then cant lock the car or arm the alarm etc, and something about NATS rings a bell, but I forget what that does - imobiliser maybe. The car may run though. TBH, I would take the hit of trailering it over to RSTuning and get them to do everything! Dont want the car to go boom!
