Configuring Logging

Last Updated: Dec 21, 2017 01:08PM EST
OBD Fusion® has the ability to automatically log vehicle data to CSV file. The data that is logged can be viewed on the Maps page (if GPS logging is active) and it can be exported for use by an external program of your choice. By default, logging is enabled and a CSV file will automatically be created when connected to the vehicle. However, you will most likely want to change the logging settings to capture the data that you want.

To configure logging, open the Settings > Log Setup page.


 

Logging Enabled


This option enables or disables the logging feature. When logging is enabled, a new CSV log file will automatically be created each time you connect to the vehicle.
 

Logging Trigger


The logging trigger configures when a frame of data to is recorded to CSV file. A single frame of data contains one point for each sensor being logged. The following options are available.

Trigger on GPS frame – A frame of data is saved to file when a new GPS reading is captured from your iPhone, iPad, or Android device. GPS readings are usually captured at a rate of one per second. If GPS is disabled or your device is not receiving a GPS signal, then there will be nothing to trigger the data logger and a CSV file will not be created. This logging trigger is the most useful when you are using the CSV logs to view data on the Maps page. If you are exporting the CSV files for use outside of OBD Fusion, then you might want to consider using one of the other logging triggers.

Trigger on PID frame – A frame of data is saved to file when OBD Fusion refreshes each sensor being logged. For example, if vehicle speed, engine RPM, and engine load are being logged to file, OBD Fusion will read one sample of each of the three items from the vehicle, then the data will be written to the log file. This logging trigger is useful if you want to export the log files and want to have data points at the same rate as they are read from the vehicle.

Trigger at a fixed sample rate – A frame of data is saved to file at a fixed sample time. The sample time is configurable on the Log Setup page. In this trigger mode, OBD Fusion keeps track of the most up-to-date frame of data read from the vehicle. When the logging sample time expires, that frame of data is written to CSV file. If the sample time is faster than the rate at which data is read from the vehicle, you will see multiple rows in the log file with the same data points. This logging trigger is most useful if you want to export the log files and want the data at a constant sample rate.
 

Log GPS Items


This options configures whether GPS data items are saved to the log file. This option must be enabled to be able to open the log files on the Maps page. The GPS items that are saved to log file are Latitude, Longitude, Altitude, Bearing, GPS Speed, and GPS Accuracy.
 

Select PIDs


This option opens a sub-screen for you to select which PIDs to log to CSV file.
 

Time Format


All CSV log files contain a column with the time at which the frame was captured. The time format option determines whether the time column is written as seconds (from the start of the log) or as a full date and time stamp.
