Pro subscribers can export session data from the Overview tab → Data Export. Shared / guest views do not show this panel. Free plans see an upgrade prompt instead of the export controls.
Use Overview export for bulk channel downloads and backups. For a quick visible-window CSV or PNG of the driver traces, use Track Map → Traces panel instead. Pit Wall charts do not export PNG/CSV yet — use Overview for raw data.
Open Data Export
- Open a telemetry file in the viewer
- Click Overview in the tab bar
- Scroll to Data Export
Requirements
| Requirement | Detail |
|---|---|
| Pro | CSV, JSON, MoTeC .ld, and .duckdb download require Pro |
| Own / library file | Export is hidden on public share links and guest views |
| Channels loaded | The picker lists channels that are already loaded in the viewer; use search and Select all as needed |
Scope
Choose how much of the session to include:
| Scope | What it exports |
|---|---|
| Full session | Entire recording |
| Selected laps | One or more laps (Out lap + flying laps). Defaults to flying laps when you switch to this mode |
| Selected stints | One or more auto-detected stints |
Lap chips match Track Map numbering: Out for the out lap, then L1, L2, … for flying laps. Click to toggle; Shift-click to select a range. Use Flying only, Select all, or Clear as needed.
Channels
- Search the list and tick the channels you need
- Select all / Clear apply to the current search results (or the full list when search is empty)
- Soft limit of 200 channels per export
- GPS channels are included when available
- Multi-wheel / multi-slot channels expand in CSV/JSON/MoTeC as
Name,Name_1,Name_2, … when those slots have data
The counter shows selected / available for the channels currently loaded in the viewer.
Formats
Export CSV
Two layouts:
| Layout | Best for |
|---|---|
| Aligned grid (wide) | Spreadsheets — one row per time step, one column per channel |
| Native rate (long) | Preserving each channel’s own sample times — columns time_s, channel, value |
For aligned CSV you can also pick the sample rate:
- Max selected channel Hz — denser grid matching the fastest selected channel
- 10 Hz — lighter file, good default for long sessions
Tip: on long races with many high-rate channels, prefer 10 Hz or native long, or export fewer channels / a lap scope, so the download stays manageable.
Export JSON
Native sample times per channel, with optional scope metadata (laps or stints you selected). Useful for scripts and custom tools.
MoTeC .ld
Creates a MoTeC log you can open in i2 or i2 Pro. Channel names follow what LMU records (for example Throttle Pos, Brake Pos, Engine RPM).
Important details:
- The file is generated from your MyLMU session, not a Motec logger recording
- MoTeC rebuilds time from each channel’s sample rate — prefer full session or a single contiguous lap/stint range for the cleanest timeline in i2
- Selecting multiple non-adjacent laps still exports, but i2 may show those segments as one continuous timeline
- Time and Distance in i2 are Motec’s own channels; open the full channel list if a channel is not on the default graph
Download .duckdb
Downloads the original uploaded recording for this file (same format LMU writes). Use this for backups or when you want the full source file rather than a channel subset.
vs Traces export
| Overview Data Export | Track Map Traces | |
|---|---|---|
| Where | Overview tab | Track Map → Traces → Export |
| Data | Selected channels, session or lap/stint scope | Visible time window, fixed driver channels |
| Formats | CSV, JSON, MoTeC .ld, .duckdb | CSV, PNG, copy playhead |
| Best for | External analysis, Motec, backups | Quick compare snapshots |
Tips
- Export before Pro ends if you need a local backup — see Free vs Pro
- For Motec workbooks, start with a small set (throttle, brake, RPM, speed) to confirm the log, then add more channels
- Community and share links stay view-only — export stays on your own Pro library files
