Real-time Graph
A live multi-channel line chart that plots any ECU output channel at up to 50 Hz. Useful for diagnosing transient fuelling, ignition, and sensor behaviour that is invisible in static gauge displays.
Tooth Logger
Captures and displays the raw crank and cam trigger signals as seen by the ECU. Essential for diagnosing trigger wheel, air gap, and shielding problems that cause sync loss and misfires.
Log Recording & Playback
Start and stop log recording directly from the app, add named markers at key moments, and replay previously recorded sessions. All log formats (MLG, MSL+MSQ, JSON) can be loaded back into any VETuner tool — including the Start Doctor.
Tune Diff Report
Compares your current tune against the original file loaded at connection time and shows a colour-coded table of every changed value. Useful for keeping track of what you have adjusted across a tuning session.
Full ECU Menu
In Beginner Mode, the sidebar shows a curated menu of the most important dialogs. VETuner Pro expands this to the complete INI-driven menu — every dialog, table, and curve defined in your ECU's definition file, accessible from the sidebar search.
VE Analysis
The VE Analysis tab uses statistical scoring to identify which cells in your VE table are lean or rich, accounting for O2 sensor lag. It generates a heat map of suggested corrections and shows a delta table of adjustments. Available in the toolbar once a wideband sensor is configured and data has been collected.
Premium Gauge Designs
VETuner Pro unlocks additional gauge styles in the dashboard gauge editor:
- SVG Design 1 & 2 — high-quality vector circular gauges
- Linear Design 1 & 2 — horizontal/vertical bar-style gauges
- Dual-Channel Design — a single gauge tile showing two channels simultaneously
