5. How to Set Up Free Car Data Logging Software

Setting up free car data logging software involves a few key steps. Here’s a general guide:

1. Download and Install: Download the software from the official website and follow the installation instructions.
2. Connect the OBD2 Adapter: Plug the OBD2 adapter into your vehicle’s OBD2 port.
3. Pair the Adapter: If using a Bluetooth adapter, pair it with your computer or smartphone.
4. Configure the Software: Configure the software to connect to the OBD2 adapter. This usually involves selecting the correct adapter type and communication port.
5. Start Logging: Select the PIDs you want to monitor and start logging data.

6. Understanding OBD2 PIDs

OBD2 PIDs are codes used to request data from a vehicle’s ECU. Each PID represents a specific parameter, such as engine speed, vehicle speed, or coolant temperature. Understanding PIDs is essential for effective data logging.

6.1. Common OBD2 PIDs

Here are some common OBD2 PIDs:

PID	Description	Units
010C	Engine Speed (RPM)	RPM
010D	Vehicle Speed	km/h
0105	Coolant Temperature	°C
0104	Calculated Engine Load Value	%
010B	Intake Manifold Pressure	kPa

6.2. Finding PID Lists

You can find comprehensive PID lists online, such as the OBD2 PID Wiki page. These lists provide detailed information about each PID, including its code, description, and units.

6.3. Example: Decoding OBD2 Data with a DBC File

To decode raw OBD2 data into physical values, you need a database of decoding rules. This is where a DBC (CAN database) file comes in handy. Here’s a simplified example:

1. Raw Data: Suppose your OBD2 logger captures a raw CAN frame with the following data for engine speed (RPM): 0x0C 0x32 0x10.
2. DBC File: Your DBC file contains the rule that PID 0x0C represents engine RPM and specifies that the data bytes need to be combined and scaled.
3. Decoding: The DBC file tells the software to combine bytes 0x32 and 0x10 to form a 16-bit value, then apply a scaling factor. For example, if the scaling factor is 0.25, the calculation might look like this:
   • Combined value: 0x3210 (hex) = 12816 (decimal)
   • Scaled RPM: 12816 * 0.25 = 3204 RPM

By using a DBC file, the software automatically interprets the raw data and displays the engine speed in a human-readable format.

7. Analyzing Logged Data

Once you’ve logged data, the next step is to analyze it. Here are some common analysis techniques:

7.1. Graphing

Graphing data allows you to visualize trends and patterns over time. You can plot multiple PIDs on the same graph to see how they relate to each other.

7.2. Filtering

Filtering data allows you to focus on specific time periods or events. For example, you can filter data to show only the time when the engine speed was above a certain threshold.

7.3. Custom Calculations

Some software allows you to perform custom calculations on the logged data. This can be useful for calculating derived metrics, such as fuel efficiency or horsepower.

8. Use Cases for Free Car Data Logging Software

Free car data logging software can be used in a variety of scenarios, including:
