Totally and utterly pointless mod to do.
Lets put it this way, most if not all new cars today work on a CANBUS system, in which all the ECU's in the car talk to each other, it isnt as simple as reprogramming the ECU to make it work, apart from the other sensors etc, you will need access to the electronic diagnostic equipment in which to see what problems and why the all various ECU's arent working.
More hassle than the MGZS is worth mate, even for bespoke dash/instrument build.
