Opening Logs
Supported File Formats
| Extension | Source |
|---|---|
.elo | Emtron display logs (ED7, ED10, etc.) |
.elf | Emtron ECU and PC logs |
Open a log via File → Open Log or by dragging a file into EmVision. The default folder is remembered between sessions.
Log Explorer
The Log Explorer tab in the left drawer lists all open log files and their laps.
Lap Selection
Each lap row provides controls for comparison:
| Icon | Purpose |
|---|---|
| Crosshairs (blue) | Set as reference lap — the primary data shown on plots |
| Circle markers (orange/green) | Set as overlay 1 or overlay 2 for comparison |
| Flag | Indicates the fastest lap |
| Best | Marks the best lap time |
Only one lap can be the reference at a time. Up to two additional laps can be overlaid for comparison. Overlay data appears in contrasting colours on plots.
Section Offsets
When comparing overlay laps, adjust the offset to align laps at a common point (for example, synchronise at the start/finish line). Use the offset editor on each lap row, or keyboard shortcuts:
| Key | Action |
|---|---|
, / . | Decrease / increase offset |
Ctrl+, / Ctrl+. | Fast decrease / increase offset |
' | Set offset to cursor (single cursor) or adjust by cursor difference (dual cursor) |
[ / ] | Select previous / next active section |
; | Toggle visibility of the selected section |
Log Summary Bar
The coloured icons in the title bar provide quick access to the reference and overlay sections currently loaded.
