No easy way to do that. The engine control module is married to the car, can't swap another DME module from another car. Only new dme's can be coded to the car.

yes you can switch computers you just have to switch the transponder in the key so that it matches the dme both cars are same year same model but with the original key that comes with the car just switch the insides but their has to be a way to override ews

What about the EWS control module rolling code? Key talks to EWS not DME. Maybe if you swicth all EWS stuff too. DME gets start signal from EWS.

I don't think you can override the theft system. You might be able to swap a computer out with a used one and get the car started, but you'll need a GT1 or equivalent to do it.
