1. What Is The Difference Between OBD2 and CAN Bus for Data Logging?

OBD2 (On-Board Diagnostics II) and CAN (Controller Area Network) bus are two distinct methods for accessing vehicle data, each with its advantages and limitations. OBD2 offers standardized data access, while CAN bus provides a more comprehensive and consistent data stream. Understanding these differences is vital for choosing the right data logging method for your needs.

1.1 How Does OBD2 Work?

OBD2 operates on a request-response protocol. The data logger, such as the Aim Solo DL, sends a request to the vehicle’s ECU (Engine Control Unit) for specific data parameters. The ECU then processes the request and sends back the requested data. The OBD2 standard defines a limited set of standardized data parameters, making it relatively simple to access basic vehicle information.

• Standardized Data: OBD2 provides access to standardized parameters like engine RPM, vehicle speed, coolant temperature, and oxygen sensor readings.
• Request-Response Protocol: The data logger sends a request, and the ECU responds with the requested data.
• Limited Data Rate: The data rate is dependent on the ECU’s processing speed and the load on the bus, resulting in inconsistent data intervals.

1.2 How Does CAN Bus Work?

CAN bus, on the other hand, is a communication network within the vehicle that allows various ECUs to communicate with each other. Data is transmitted continuously over the CAN bus in the form of messages, and data loggers can “listen” to these messages to record the data. This method provides a more comprehensive and consistent data stream compared to OBD2.

• Constant Data Stream: Data is transmitted continuously at a constant rate.
• Comprehensive Data: Access to a wider range of parameters, including those not available through OBD2.
• Consistent Data Rate: Data is transmitted at a fixed frequency, ensuring consistent data intervals.
• Requires Decoding: Needs specialized knowledge to translate raw CAN data into meaningful information.

2. What Are The Advantages of Using CAN Bus Over OBD2 for Data Logging?

Using CAN bus over OBD2 for data logging offers several advantages, especially in terms of data consistency, data availability, and real-time monitoring. These advantages make CAN bus the preferred choice for advanced data analysis and performance tuning.

2.1 Improved Data Consistency

CAN bus provides a constant and consistent data stream, ensuring that data is transmitted at a fixed frequency. This consistency is crucial for accurate data analysis and performance monitoring. According to a study by the Society of Automotive Engineers (SAE), CAN bus systems provide more reliable data acquisition compared to OBD2 due to their deterministic nature.

• Fixed Frequency: Data is transmitted at a fixed frequency, such as 100Hz (10ms), ensuring consistent data intervals.
• Reduced Latency: Lower latency due to the continuous data stream, allowing for more responsive data logging.
• Accurate Analysis: Consistent data intervals enable more accurate calculations and analysis.

2.2 Increased Data Availability

CAN bus offers access to a wider range of data parameters compared to OBD2. This includes parameters specific to the vehicle’s make and model, as well as data from various ECUs within the vehicle.

• Vehicle-Specific Parameters: Access to parameters specific to the vehicle’s make and model, such as individual wheel speeds, steering angle, and brake pressure.
• Data from Multiple ECUs: Ability to monitor data from various ECUs, including the engine, transmission, ABS, and stability control systems.
• Comprehensive Monitoring: More comprehensive monitoring of vehicle performance and behavior.

2.3 Real-Time Monitoring

CAN bus enables real-time monitoring of vehicle data, allowing for immediate feedback and adjustments. This is particularly useful for track days and performance tuning, where real-time data can help optimize driving and vehicle settings.

• Immediate Feedback: Real-time data allows for immediate feedback on vehicle performance.
• Optimized Driving: Helps optimize driving techniques and vehicle settings based on real-time data.
• Performance Tuning: Enables precise adjustments to engine and vehicle parameters for improved performance.
