Thermostat question

[jb92563]

With all the electronics these days I cant imagine why the coolant system is not ECU controlled to maintain the perfect operating temperature.

Perhaps the benefit does warrant the extra effort to add the necessary components?

Once the thermostat is open operating temperature is ECU controlled by the fans. With thermostat open it is the air across the radiators that help to regulate operating temperature.

Buy a new Boxster and you will get your wish; they call it a "thermal management system".
