OBDViz Analyzer is our combined multi-format visualizer tool. It is a premium browser-based app designed to open vehicle logging files generated by popular apps like Torque Pro, FORScan, OBD Fusion, and Carly. It reads coordinates from CSV tables and translates them into responsive dials, customizable charts, windowed stats grids, and shift highlights.
Absolutely. All parsing, calculation, and rendering occurs entirely inside your local browser sandbox using client-side JavaScript. We do not transfer your files to any remote API endpoints or databases. You can load logs while completely offline.
OBDViz Analyzer automatically detects delimiters: whether your log is saved as a
comma-separated (,) or semicolon-separated (;) CSV, the parser
will separate columns properly.
Additionally, it automatically detects date-time calendar strings (like Torque Pro's
2026-05-27 22:15:01.000) or relative timestamp columns (like
time(ms), Time (s), or Timestamp) and standardizes
them into relative milliseconds starting at 0, making them immediately compatible with our
simulation and graphing engines.
Yes. The dashboard displays four dials (RPM, Speed, and two Auxiliary gauges). Click the **Settings Gear (⚙️)** on any gauge to trigger a dropdown populated with all numeric parameters parsed from your CSV log. Selecting a PID re-maps the dial title, unit boundaries, and animation curves immediately.
If you're studying a specific event (e.g. a dyno pull or a shifting sequence), drag a Zoom Box on the timeline chart to lock onto that window. Click **Export Zoomed CSV** in the chart controls. The system will compile only the telemetry rows visible inside your current zoom boundaries and download a valid, trimmed CSV file.
Yes. In addition to Torque Pro, FORScan, OBD Fusion, and Carly, we are continuously expanding compatibility for VCDS, Cobb Accessport, HPTuners VCM Scanner, and generic custom CSV log sheets. As long as your file has a time/timestamp column and numeric data rows, our auto-detection engine will map it.
Choosing an adapter depends on your use case. For live dashboards and monitoring, wireless adapters like the premium OBDLink MX+ or budget-friendly Veepeak BLE+ are excellent. For advanced configuration or programming (such as Ford configuration in FORScan), a wired adapter like the vLinker FS USB is required for safety. Avoid cheap generic clones, as their unreliable connection can corrupt ECUs and brick your vehicle modules. Read our complete OBD2 Hardware Guide for details.
