Regardless of the DME, you will need to sort out the CAS/EWS and perhaps VO programming. As Hass mentioned, the MSV70 may not support your car.

If it was my project, I'd convert the engine to work with the MSV80 and find someone that could prep an MSV80 to match your car. When you are done, everything will work like an OEM setup.

The engine conversion will be pretty easy, start with the MAF and throttle body but check real OEM for the rest of the sensors. You might find one or two more that need changed. 30 minutes research, max.

The DME and CAS programming, Find someone that can Match the EWS keys in your CAS and while they are setting it up, get a tune designed for the three stage manifold you surely have on your new motor.

Have you replaced the gaskets? If the valve cover is coming off.....MILVS while the motor is still on a stand.
