The FADEC system was designed by two retired Pratt & Whitney engineers in a small shop near Hartford CT that they adapted from the NorthStar auto engine. Their design and in fact their whole company was purchased by Continental Engines and the system is now available on some of the Continetals. The Liberty two place composite trainer has one of these engines and a lot of the new aircraft also have them installed. If you want more info punch into Google and type in FADEC ignition systems.
