The Rolls Royce RB211 has varying amounts of EEc control, but none of them are FADEC.
The -22B and -524B and D had a small EEC for overtemp control.
The -535 had a limited EEC in the E and E bay.
Then the -524G/H on the B744 and B767 has a full authority EEC, but it cannot be a FADEC because the airflow control is entirely analogue. This air pressure operated, no electrics, no moving parts VIGV control box was so reliable that RR kept it on the -524 even when the whole fuel system went digital.
