M-JET Flasher is the official app for the M-JET Flasher Dongle. It connects via Bluetooth to your dongle and transfers verified firmware to the ECU of your BRP vehicle – for Sea-Doo on the water and Can-Am on trail, dune, and road. The entire process is guided and clear: identify the vehicle, select a firmware version, verify, transfer. Before every flash, a safety check runs (voltage, connection, session) so nothing is left to chance. You can always revert to stock firmware. Features: • Identify your vehicle via dongle and display firmware versions matching your SW number • Guided flashing with pre-check and progress indicator • Revert to stock anytime • Read fault codes grouped by ECU • Service functions for common maintenance tasks • Garage: your vehicles and their history in one place • Direct in-app support • Automatic firmware updates for the dongle • Available in 7 languages Note: This app requires the M-JET Flasher Dongle. Without the hardware, no functions are available. A new firmware version is available immediately in most cases; in rare cases it will be prepared briefly after your automatic request.
