You don't need a brand new 7.8 DME, but if you use someone elses, then you need to make sure that you get the immobilizer, and the keys from the donor car. This is because the DME and the immobilizer are keyed together. You can always get replacement keys to be cut and reprogrammed to work with the ECU, but most of the time it's just easier to get the electronic key portion from the donor car. If you don't get the immobilizer from the donor car, then you will have to purchase a brand new one and program the DME to work with that one.
