In fuel injected Ducatis, the coolant temperature sensor is used by the ECU to stop warm-up fuel enrichment at around 80°C. So from a fuel correction standpoint, the proper operating temperature is ABOVE 80°C. Reduce the coolant temperature below this and you're not operating efficiently. In fact, if your engine is consistently running at 60 - 70°C in cooler weather, you should probably cover part of your radiator to reduce cooling airflow. The fact is that running cooler is not better for your engine. YOU may feel more comfortable, but the bike is not operating at an optimum point on its fuel map. |
