Tuning for Sea-Doo RXP-X 350
The Sea-Doo RXP-X 350 is the new muscle craft flagship for the 2027 model year. With the M-JET Flasher, you can get even more acceleration and top speed from the 350 hp engine, directly via smartphone and reversible at any time.
Engine & Technology
The engine is the supercharged Rotax 1630 ACE with around 350 hp. Engine control is handled by a locked Bosch MG1 control unit. The M-JET Flasher reads, saves, and flashes the software directly via the diagnostic port, controlled by smartphone, without a laptop and without a workshop.

What Does Tuning Achieve?
The M-JET Flasher unlocks noticeably more power: stronger acceleration, more direct throttle response, and higher top speed. Every change is controlled and can be reset to factory settings at any time, ideal for warranty, resale, or winter storage.
Important: ECU Unlock
The 350 hp models use a locked Bosch MG1 control unit. A one-time ECU unlock is required for tuning. You can send us your control unit for this or choose a pre-prepared replacement control unit directly; the flasher will then transfer all relevant data. All options can be found in the configurator.
