DIUS Flasher 4 — One Tune File for Sea-Doo
This product is intended for a single tuning firmware file operation on supported Sea-Doo personal watercraft.
Typical Use
- Single ECU performance reprogramming
- Throttle response improvement
- RPM and fuel map optimization
If you already have an MPI-2 or MPI-3 diagnostic interface with the required cable, you can purchase one tuning firmware file matched to your Sea-Doo model and ECU configuration.
This is the most convenient solution for customers who need only one specific tune firmware without buying a larger package.
