Telemetry Analysis

The Telemetry Analysis feature is the core of TrackOut. It lets you upload session files, visualize your driving data across multiple channels, and compare laps to find where you can improve.

Accessing telemetry analysis

Navigate to the Analytics page and select the Telemetry tab. From here you can upload a new file or load a previously saved session.

Key features

XRK/XRZ file support

Upload files directly from AIM data loggers. Files are parsed in your browser with no server round-trip required. XRZ files are automatically decompressed before parsing.

Multi-lap comparison

Compare up to 4 laps side-by-side with distinct color-coded traces. See exactly how your driving differs between laps at every point on track. Learn more in Lap Comparison.

GPS track mapping

Visualize your driving line on an interactive satellite map. The line is color-coded by speed, and braking zone markers show where you begin and end braking. When a known track is detected, the official centerline is overlaid for reference.

Channel analysis

View speed, G-forces, brake pressure, throttle position, RPM, and other channels plotted against track distance. Hover on any chart to see exact values at that point.

Braking zone detection

TrackOut automatically detects braking zones and provides statistics for each one, including entry speed, exit speed, peak braking G, and duration. Compare braking zones across laps to find where you can brake later or carry more speed.

Delta time trace

The delta trace shows cumulative time gained or lost compared to a reference lap. Steep slopes highlight sections where the most time is being gained or lost, helping you prioritize which corners to work on.

Session saving

Save parsed sessions to your account so you can revisit them later without needing the original file. Sessions are compressed and stored securely. See Saving Sessions for details.

Typical workflow

1. Upload an XRK/XRZ/VBO file or load a saved session
2. Review the lap list and identify your fastest and average laps
3. Select 2-4 laps to compare
4. Use the track map, speed chart, and delta trace to find time-gain opportunities
5. Check the braking zone table for corner-specific insights
6. Save the session if you want to revisit it later
