A good simple carby setup is more efficient than a good EFI set up in a modern car.
Do you have a source for this?
I went to a lecture by a Rover engineer some years ago who stated that they got more performance out of a 3500 (V8) SD1 car with Weber carbs than with the best EFI set up. The car buying public was clamouring for injected cars at the time though, so the Rover Vitesse was injected, simply because that was what would sell.
Going back to aero-diesel engines, mechanical injection is simple and reliable, however it is common rail (electronic) injection which gives the real gains in performance, economy and engine longevity, as the forces in the engine can be controlled so much better.
Piezo injectors give even better control and can allow more power to be extracted from an engine, but are, or at least were recently, prone to unreliability.
With electronics on a diesel aero engine, you have a choice between mounting the electronics on the engine or engine mount and have them shake around with the engine, or mount them in the airframe and run the risk of the wires fatiguing with the relative movement to the engine.
