Compared the previous E36 M3, the E46 model gained new camshafts and an increased EWS is BMW's 'brand' for their immobilizer systems. E39's have version 3.3. There is an "EWS Module" that is the brains of the system, however it talks to other parts of the car as well. DME is BMW speak for the engine computer aka ECU in generic car-world.
