The BlueDriver scan tool, a highly-rated Bluetooth OBD2 scanner available on Amazon, offers enhanced diagnostic capabilities for Honda vehicles. This article delves into real-world experience using the BlueDriver scan tool to monitor live data on a brand new Honda CRV, providing insights into engine temperature, fuel trims, and more. While no fault codes were present (as expected with a new vehicle), exploring the live data reveals interesting performance characteristics.
Uncovering Engine Temperature Trends with BlueDriver
Using the BlueDriver, the engine coolant temperature (ECT1) consistently ranged between 80°C to 85°C (176°F to 185°F) once the engine reached operating temperature. This range appears slightly lower compared to typical engine operating temperatures. Remarkably, this temperature band remained stable irrespective of driving conditions, even during extended idling periods or stop-and-go traffic. The dashboard gauge, however, only registered a reading once the temperature reached approximately 55°C (132°F), reaching the top mark around 75°C (165°F). This suggests the thermostat’s operation is linked to achieving engine operating temperature, as evidenced by the ECT2 (radiator coolant) temperature only beginning to rise after the engine reaches its optimal temperature.
Fuel Trim Analysis with the BlueDriver Scan Tool
Consistent negative fuel trim readings were observed, with short-term fuel trim (STFT) averaging around -5.5% and long-term fuel trim (LTFT) around -8%. These readings were recorded while using E0 fuel. Subsequently, the vehicle was filled with E10 fuel to assess its potential impact on fuel trim adjustments. Future observations will determine if switching to E10 results in a shift towards positive fuel trim values.
Anticipating Winter’s Impact on Performance
The forthcoming winter season presents an opportunity to gather further data. The vehicle is operated in a region known for its extremely cold winters and driven on distances considered “short” by Honda’s standards. It will be insightful to monitor how these environmental and driving conditions influence the engine temperature and fuel trim readings captured by the BlueDriver scan tool. Continuous monitoring will reveal how the CRV’s engine adapts to colder temperatures and shorter trips. Future analysis will focus on comparing data collected during warmer months with readings obtained during the winter season. This will provide a comprehensive understanding of how the Honda CRV’s engine performance varies throughout the year. The BlueDriver scan tool proves invaluable for gaining these detailed insights.
