[QUOTE="soggie, post: 1928021, member: 6245"] Lets take 2 rpm monitors for example. A - process 1000 signals per second B - process 100 signals per second Objetive: Rev cut exactly at 7000 rpm. Rate of climb: 3000 rpm per second Ok, now you step on the pedal, both engines hit 6000 rpm after 2 seconds. Now what? On the third second, both rpms climb to 7000, and A cuts it at 7000, while B cuts it at probably 8000-8500 rpm. Why? This is because B's processor is much slower, and couldn't accurately trigger the event scheduled to happen on that very moment, due to slow update-feedback process. The faster ECU captures the change easily, and accurately does its work. In an engine where everything is delicate - an imbalance of fuel/air might lead to serious complications, the speed and accuracy of the ECU becomes a major factor, as in all real-time applications.
