EmVision User Guide
EmVision is Emtron’s log analysis application for reviewing data recorded by ECUs, displays, and PC logging. It is available via EmUpdater.
Use EmVision to open log files, compare laps, overlay multiple sessions, build custom analysis layouts, and create math channels for derived measurements.

The EmVision window is divided into three areas:
| Area | Description |
|---|---|
| Left drawer | Log Explorer, Page Explorer, and Workspace Explorer |
| Centre | Plot panes showing the active analysis pages |

The title bar shows the current workspace, X-axis mode (Time or Distance), and open log files. A progress bar at the bottom indicates log loading status.

Typical Workflow
- Open a log via File → Open Log, or download from a device via File → Log Download.
- Select laps in the Log Explorer — set a reference lap and up to two overlay laps for comparison.
- Open or create pages with the plot types you need — see Plot Types.
- Use the cursor to inspect values at any point — see Cursors and Measurements.
- Create math channels for derived calculations.
- Save your layout as a workspace for reuse on future logs.
Multi-Window
EmVision supports up to four simultaneous windows. The first window is the Primary window and hosts the Workspace Explorer. Secondary windows share the same log data but can show different page layouts.
Use File → Create Window to open additional windows. Each window maintains its own pane layout and page selection.
