On both the CVH and the Zetec engines, the gauge sender and the ECU sensor are totally separate; not sure what you mean by an ECU switch? they are both thermistors (resistors which decrease in value with applied temperature).
Just a temperature gauge reading alone shouldn't affect economy. On mine, you can see/hear the idle speed drop in one jump as the engine warms up, which indicates that the coolant temperature sensor is working. I had an issue with poor low-revs acceleration on my CVH-engined H4 (a flat spot about 1800 rpm) - replacing the intake manifold air temperature sensor seems to have helped significantly, although there is still a little hesitation when the engine is warmed up.
