I was simply using the example of my Z4 which has a 2.5l gasoline engine and an electronic controlled thermostat as an observation of how quickly the temperature can change in the engine when the thermostat is open very quickly (and conversely shuts quickly when the ECU stops manipulating it)... I really didn't want to sidetrack the discussion, just drawing a parallel to what appears to be a odd behavior that London Lad reported.
If it's not the thermostat, then what's not working right?
