It may be me.. .. our heater in the Plus Six seems to work a little faster from cold since its 3rd radiator and ECU reflash for the revised control of the engines rotary water flow valves.. The engine certainly now warms up much more progressively. Prior to the reflash the engine would come up to working temp and then dip temp as the cooling went to the radiator then come back to normal temp..
Maybe its reduced the thermal shock caused by the previous ECU software.
