You will need to swap to a 7.8 DME, as they are different computers, add the wiring to control the VarioCam Plus valve lift solenoids, and change a few pins in the harness, then program the proper 3.4 map into it with a PST2 or PIWIS. Your car with the 7.2 DME has VarioCam, the 3.4 has VarioCam Plus, which is a totally different system and is controlled differently.
