WATCH: How Map-Controlled Thermostats Work
An operating map stored in the engine control unit has predefined set points for the vehicle load and speed that determine the ideal coolant temperature for the driving situation, and when and how coolant should be circulated.
WATCH: Understanding Automotive Thermostats
Thermostat technology is changing and giving more control to the engine computer, which is a good thing for gas mileage.
