EmVision Features

EmVision is Emtron’s PC log analysis application for reviewing data recorded by ECUs, displays, and PC logging. It is available via EmUpdater.

This page is a high-level features list. For a first session, see Getting Started. For menus and layout, see the EmVision User Guide.

Log Files and Data Sources

Open Emtron display logs (.elo) from ED7, ED10, and related products
Open Emtron ECU and PC logs (.elf)
Open logs via File → Open Log or drag-and-drop
Download logs over the network from a connected display or ECU (File → Log Download)
Download all to fetch every missing or out-of-date log in one step
Export the reference log to CSV or Emtron log (whole log or visible window, channel selection) — see Export Log
Import GeoJSON track maps for circuit GPS overlay

Lap Comparison and Overlay

Set one reference lap as the primary analysis section
Overlay up to two comparison laps (same log or other open logs)
In-laps and out-laps can be used as reference or comparison
Automatic best-lap and fastest-lap indication in the Log Explorer
Align overlays on the plot with Shift+drag (comparison 1) and Alt+Shift+drag (comparison 2)
Keyboard offset controls for fine alignment
Section visibility toggle and section cycling

Workspaces and Pages

Workspaces save pane layout, open pages, plot configuration, and floating gauges
Create, rename, duplicate, and switch workspaces from the Workspace menu or Workspace Explorer
Workspace search (Ctrl+W)
Pages are reusable analysis layouts stored as individual files (.elp)
Page Explorer and page search (Ctrl+P)
Up to four plot panes per window (Ctrl+1–Ctrl+4)
Auxiliary full-width page row above the main grid (Ctrl+`)
Sample pages included for common analysis themes (boost, knock, traction, track, torque, and more)

Multi-Window

Up to four simultaneous EmVision windows
Primary window hosts the Workspace Explorer
Secondary windows share open log data and can show different page layouts

Plot Types

Six plot and view types, mixable in any page layout:

Type	Purpose
Line Plot	Multi-channel traces vs time or distance
Scatter Plot	X–Y channel relationship with optional Z colour
Track Map	GPS vehicle path on circuit outline
Lap Timing	Sector and lap split time table
Gauge Area	Dashboard-style gauges at the cursor
Lap Matrix	Colour-coded channel statistics across laps

Line Plot

Multiple channels with independent Y-axis scaling
Scaling modes: scale to fit, scale to reference, scale from channel database
Event markers (individual selection or show all events)
Lap and sector milestone bands
Corner and straight segment highlighting
Drag-and-drop channels from the measurements panel
Channel highlight and hide toggles

Scatter Plot

X, Y, and optional Z (colour) channel assignment
Connecting lines and marker type selection
Colour range boxes for Z-channel segmentation
Overlay comparison laps with distinct colours and shapes
Soft falloff option for dense point clouds
Show/hide comparison toggles and per-compare marker shapes

Track Map

Vehicle position marker with configurable vehicle dimensions
Track outline from imported GeoJSON or log GPS data
Track-following or car-following zoom (F10)
Smooth pan and zoom

Lap Timing

Sector times per lap, best sector and best lap highlighting
Special lap columns (in-lap, out-lap)
Totals row from log lap timing data

Gauge Area

Multiple gauge styles in a single pane
Values update as the cursor moves during analysis and playback

Lap Matrix

Configurable channel rows with colour bands
Drag rows to reorder
Quick identification of highest/lowest values per channel across laps

Layout Editor

Change plot type per cell
Nested horizontal and vertical splits within a page
Drag dividers to resize; ratios saved with the page
Right-click a plot to change type, split, or delete without full edit mode
Maximise a single plot to fill its pane
Navigator channel (global under Settings) for playback preview

Cursors and Measurements

Single cursor with click-to-position and keyboard pan/zoom
Dual cursor mode (D) with swap (S) and align secondary (B)
Delta values between cursors in the measurements panel
Playback animation of the cursor through the log (time mode)
Measurements panel (F8): sector/lap context, all channel values and units
Click a measurement to highlight the channel on plots
Time or distance X-axis (F9)

Math Channels

Offline analysis maths using emexpr (same language as Display Studio)
Full syntax reference: Math Functions — see also Math Channels
Math channels can reference other math channels
Enum lookup for status channels — insert named state values into expressions
Binary (0b) and hex (0x) integer literals
Client user channels for custom names alongside maths
Not written back into the original log file

Circuit and Drag Analysis

Auto-detect circuit vs drag analysis mode, with forced overrides
Circuit: lap and sector milestones from GPS and race data
Drag: distance-based strip markers (60 ft, 330 ft, 660 ft, 1320 ft, etc.)
Generate drag markers from cursor or from a trigger channel
Clear drag markers on the selected section
Configurable circuit speed, drag speed, and drag trigger channels

Floating Gauges

Draggable, resizable overlays above all plot content
Gauge types: bar, radial, steering wheel, force vector
Colour bands, min/max range, and fill direction
Saved and restored with the workspace

Full keyboard shortcut set (see Keyboard Shortcuts)
Configurable scroll/zoom acceleration and boost
Left drawer: Log Explorer, Page Explorer, Workspace Explorer (F7)
Right drawer: live measurements at the cursor
Enum-aware status channel display (named states instead of raw numbers)
Multi-language UI support

Performance and Platform

Fast log open, pan, zoom, and cursor interaction
Efficient multi-lap comparison on the same log
Responsive math editing and channel add/remove
