Maintenance reliability plays into the marketing attraction, too. Theoretically, with the engines built-in protective algorithms against over-temping and over-revving, the engine wont be subjected to abuse by a ham-fisted pilot. Further, the ECUs are sucking up and storing a lot of data, transmitting some directly to the cockpit for the pilots real time analysis and storing a lot more for use by techs to diagnose maintenance issues, using a code-type system similar to modern cars.
