DIUS Flasher 4.0 is a professional ECU programming solution developed for BRP Sea-Doo watercraft equipped with 4-TEC and E-TEC engines.

The software allows technicians and performance enthusiasts to safely replace or restore standard ECM firmware as well as install tuning firmware with optimized fuel mapping, ignition timing and engine limit parameters.

If you own a Sea-Doo Jet Ski and want to improve overall performance through ECU reprogramming, you can purchase a single tuning firmware file specifically designed for your PWC model.
Each tuning calibration is developed to provide improved throttle response, increased top speed potential and optimized engine efficiency.

The complete database of available stock and performance firmware versions can be viewed directly inside the DIUS Flasher 4.0 software after installation.

The DIUS Flasher kit uses the same hardware interface as BRP diagnostic systems for 4-TEC and E-TEC platforms.
Compatible interfaces include:

  • MPI-2 diagnostic interface

  • MPI-3 diagnostic interface

  • BRP diagnostic communication cable

A full technical description of DIUS Flasher software features, firmware database structure and programming workflow can be found in the dedicated software documentation section.

You can download DIUS Flasher 4.0 and complete user registration to access the firmware database and programming tools.

Important Notice

When selecting ECU firmware, special attention must be paid to matching hardware part numbers and firmware calibration identifiers.
