VE Tuner

Tuning in the browser

No gauges configured. Connect to ECU to load gauges.

Dialog

Table

Customize Gauges

Select which gauges to display. Changes will be saved automatically and persist between sessions.

ECU Settings

Configure ECU-specific settings defined in the INI file. Changes are applied immediately and stored locally.

Connection Setup

1. Load Configuration Files (Optional)

INI and MSQ files are optional. The app will auto-detect and cache INI based on ECU signature.

2. Debug Settings

Debug level controls console logging. Trace adds low-level communication timing and enables the /trace stream.

4. Connect to ECU

Connect to ECU through a WebSocket bridge server

File Required

The ECU definition requires an external file to function correctly.

Please select the following file from your computer:

Once selected, this file will be saved in your browser's local storage for future use.

Browser Compatibility

We're sorry! VETuner is currently unable to run in your browser.

To talk directly to your ECU, this application relies on the Web Serial API, which isn't supported by all browsers just yet.

For the best experience, we recommend using a modern Chromium-based browser such as:

  • Google Chrome
  • Microsoft Edge
  • Opera

You can find more details about which browsers work at caniuse.com.

We apologize for any inconvenience this may cause.

Project Status & Capabilities

Project Status & Capabilities

Welcome to VETuner. This is an early-access web-based tuning application. Here is a summary of what currently works and what is still in development:

✅ What Works

  • Direct ECU Connection: Connect via USB/Serial (Web Serial API) or WebSocket Bridge.
  • Real-time Dashboards: High-speed gauge updates (50Hz+) based on INI definitions.
  • Tuning Editors: Inline editing for VE tables, ignition maps, and enrichment curves.
  • Tune Management: Loading and saving of MSQ (tune) files.
  • Calibration Tools: Sensor calibration using built-in generators (Thermistor, Linear, etc.).
  • Data Logging: Real-time logging to MSL format files.

⚠️ Known Limitations

  • Experimental Status: This software is early-stage. Expect bugs and potential disconnects.
  • Large INI Files: Complex INI files with heavy macro usage may take several seconds to load.
  • Advanced Features: Some advanced ECU features (SD logging, specialized CAN commands) are not yet implemented.
  • Mobile Support: Currently optimized for Desktop browsers (Chrome/Edge).
