I had a Continental in my last aircraft with Fadec. I can't say it was the best thing since sliced bread having those electronics. If anything was wrong like a plug or something similar, a warning light comes on and you have no idea what's wrong until the LAME drops in. It was getting rather frustrating in the end.
If they can have a good reliable EMS included with it that accurately reports what is wrong, rather than just a warning, then great, it will be a good thing.
