"Unlike PMC or EEC there is no cable linking your thrust lever to the control unit in the engine."
It really depends on the aircraft, HP....
The 747-400's with RR's for example, have EEC's (mounted on the engines), but they have no mechanical cables going from the cockpit to the engine. The EEC's are the rough equivalent of the ECU's mentioned in "delarocha"'s post.
However, I am told that the RR engine management system falls outside the category of "FADEC" as there are a few engine components still not under the control of the EEC.
