100% Client-Side Privacy

Your log files never leave your computer. Telemetry parsing is performed directly in your local browser sandbox, giving you complete data protection and instant load speeds.

Multi-Axis Timeline Graphs

Compare engine RPM, speeds, temperatures, and throttle coordinates simultaneously. The analyzer automatically groups data columns by unit types onto separate axis tracks, supporting all major logging tools.

Dynamic Gauge Playback

Run a virtual drive simulation of your logs. Click the settings gear next to any instrument dial to map it to any parameter (PID) captured in your log session.

How to Export and Graph Your Logs

OBDViz Analyzer parses standard CSV files exported by several popular mobile OBD2 loggers.

2
Export as a Delimited CSV File Save the session log as a CSV. The analyzer automatically detects comma (,) or semicolon (;) delimiters and absolute or relative time ranges.
3
Drag & Drop into OBD Analyzer Launch the OBD Analyzer, upload your CSV file, choose which parameters to map, and start playback to inspect physical telemetry!
