According to Turbomeca the Arriel 1E2 engines couldn't be upgraded with a FADEC and Turbomeca isn't interested in major modifications on this "old" engines. And FADEC-ing is the part of the engine manufacturers not ECD.
It's right there are plans to upgrade the EC 145 on the next development level with a 5-bladed rotor, new MR Gearbox and FADEC equipped engines.
Just ask the maint. engineer to definite the therm "soon" ...
