Tuning Editor is free and runs on Windows 10 or later (64-bit). You download it once from the MTX product page and run a short installer.
Open the Tuning Editor product page and click Download to get the latest installer.

Run the downloaded file. The setup wizard lets you choose the language (English or Italian), accept the licence agreement, confirm the install location and components, and optionally create a desktop shortcut, then installs.

On the final screen you can launch Tuning Editor straight away. The installer is self-contained — it adds the required Microsoft Visual C++ runtime automatically, so there is normally nothing else to install; a restart is occasionally suggested.

Tip — updates are free and the application can check for them itself, so you only need to download manually for the first install. See updates.
Lets you quickly disable fault codes to turn off the MIL light directly from your ECU file. Available in Standard and PowerTools editions with advanced scripting and online presets to remove faults by component groups.
