OBD2 Data Logger - Easily Record Your Car Data
Do you want to record OBD2 data from your car?
This intro recaps the basics of OBD2 logging, the top 4 benefits and example use cases. You can also download sample OBD2 data from an Audi A4 (speed, RPM, ...).
Note: In contrast to most OBD2 dongles/scanners, the CANedge logs time series data to an SD card - which you can freely process via 100% free software/APIs. Learn below why the CANedge is ideal for OBD2 data logging at any scale.
How does OBD2 data logging work?
First, let us briefly recap the basics of OBD2: OBD2 offers a standardized set of parameters (OBD2 PIDs) that you can record - and easily decode - across most cars.
To log OBD2 data involves 3 simple steps:
- Configure your OBD2 logger with a list of OBD2 PIDs
- Connect it in your car via an OBD2 adapter to start logging
- Extract the SD and decode the data via the free software/API
Top 4 benefits of OBD2 data logging
OBD2 logging lets you collect data from practically any car - below are the top benefits:
OBD2 data lets you e.g. monitor/optimize driving behavior and tune your car. OEMs can use the data to analyze the performance of new prototype parts in the field
Rare issue diagnostics
Rare issues in cars may occur briefly while driving, yet not during repairs. Logging the OBD2 data lets you analyze the period around an event to troubleshoot the problem
Car fleet management
OBD2 logging at fleet level enables e.g. driver behavior research, fuel cost reductions, reduced breakdowns, compliance, dispute handling and other valuable benefits
Data control & custom integration
With an OBD2 logger, you record the raw time series data, which can be extracted via SD or uploaded to your own server - for easy custom integration via open APIs
