This marks a key turning point for professional tuners and commercial vehicle workshops, opening the door to a broader range of high-value vehicle types without the need for separate tools or software add-ons.
From today, the new Magic Motorsport FLEX software license means that FLEX users can access full OBD, Bench, Boot and OBD Full protocols for ECUs, TCUs, and DCUs fitted to:
-
Trucks
-
Agricultural machinery
-
Buses and coaches

Industrial vehicles
This new Magic Motorsport FLEX software license now provides comprehensive coverage for one of the most demanding areas of tuning and ECU management.
A Major Software Expansion: Version 7.18.0.0
Coinciding with the release of the new licence is FLEX software version 7.18.0.0, which brings 32 new protocols specifically tailored to the heavy-duty vehicle market. This includes support for 23 different control units, spanning a wide range of OEMs and applications.
The update includes support across all tuning access methods – OBD, Bench, and Boot – and introduces some exclusive capabilities, such as:
-
Cloning via Bench mode for DAF Delphi ETC3 (KWP)

Which Software Licences Support This?
The new heavy-duty protocols are included in:
-
FLS0.5M – FLEX Full Master
-
FLS0.5S – FLEX Full Slave
-
FLS0.15M – FLEX Heavy-Duty OBD/Bench/Boot Master
-
FLS0.15S – FLEX Heavy-Duty OBD/Bench/Boot Slave
Whether you’re a new FLEX user or already running a Full Master setup, the FLS0.15 licence expands your tuning capabilities without hardware upgrades.
Why This Matters for Your Business
For garages and tuners operating in mixed commercial environments – where trucks, plant equipment, and agri vehicles need regular calibration or repair – this release significantly improves workflow efficiency and vehicle coverage.
Rather than managing a patchwork of tools, software, and files, the FLS0.15 licence consolidates access into a single, unified system. You can now read, write, clone, and restore a wide range of ECUs from heavy-duty vehicles, whether you’re tuning for performance, fuel economy, or diagnostics.
Stay Ahead with Professional Training
If your team hasn’t yet worked with heavy-duty ECUs, the Viezu Technical Academy offers training programmes specifically designed around commercial vehicle tuning and the use of FLEX tools.
