How do mpg gauges work?

Instant mpg displays give drivers the exact miles per gallon they’re getting at that very moment. The devices have sensors that take into account the car’s engine speed (how hard the engine is working), the fuel-flow rate, manifold pressure and throttle position. An instant mpg readout takes this idea one step further.

How does a fuel consumption meter affect your mileage?
