'''DME'''⏎
Digital Motor Electronics''' (DME) is a microprocessor based system that controls the ignition, fuel injection, oxygen sensor and numerous ancillary functions. The DME provides raw data to an on-board computer that uses an alphanumeric display to provide you with information such as the average fuel consumption, the distance you can still cover with fuel in the tank, an average speed, outside temperature and more. 

(contracted; show full)

In the event of an electrical fault, DME can reconfigure itself to bypass the problem, and DME can diagnose itself for quick and efficient trouble-shooting.

[[Circuit]] diagram of early DME system

The core of a DME [[application]] are [[microprocessor]]s. [[Microprocessor]]s work at astonishing speeds. The core of central engine management in the current [[BMW]] M3 executes nearly twenty million instructions per second (20 MIPS). [[Microprocessor]]s also have a reputation for being extremely reliable. They are designed for a lifespan of at least 150,000 active hours. A car by comparison, is expected to survive 4,000 hours of use.
