Maptuner NANO BRP Sea-Doo ECU Tuner & Speed Limiter Override

Maptuner Dealer — Hundreds Sold
Buy your Maptuner NANO BRP from JETSEAHUB, a UK dealer with hundreds sold, UK-held stock and next-working-day delivery available.
Control your Sea-Doo’s tuning and diagnostics from your smartphone. The compact, water-resistant Maptuner NANO plugs directly into the BRP diagnostic port and connects to the MyMaptuner app through Bluetooth. Compatible with iPhone and Android, with no separate connection cable required for a standard installation.
Sea-Doo 300 & 325 Speed Limiter Override
Remove the factory GPS speed restriction on supported Sea-Doo models while retaining the stock ECU:
• 300hp models: 2018–2025.
• 325hp models: 2024–2026.
No ECU tuning licence is required for the speed-control override function.
Compatible models can start automatically in Sport Mode, with Touring Mode selectable manually. Automatic Sport Mode start-up is not supported on models with the 10.25-inch touchscreen.
The speed-control override removes the factory speed restriction; it does not itself remap the engine or increase horsepower.
ECU Tuning — Performance Software From Your Smartphone
With a separately purchased RIVA Maptuner tuning licence, load available performance tunes onto a supported ECU, switch between suitable tunes and return to stock software when required.
One tuning licence is required per vehicle. The same NANO device can be used to programme multiple supported vehicles, each with its own licence.
Tune availability depends on your model, year, ECU and modifications.
Important for 325hp owners: full RIVA ECU tuning requires a compatible unlocked ECU and tuning licence package, purchased separately. This is different from the licence-free speed-control override.
Live Engine Data & Fault-Code Diagnostics
View live engine data and read or clear supported fault codes through the MyMaptuner app without purchasing a tuning licence.
Data logging is available with a valid tuning licence. Available readings and functions depend on the vehicle and equipment fitted.
Optional Sea-Doo DESS Key Programming
Programme compatible Sea-Doo keys and lanyards at home with the optional Maptuner BRP Home Service Application, sold separately.
This application is vehicle-specific. DESS key programming is not supported on 2003–2011 models equipped with a Siemens ECU.
Installation & Accessory Compatibility
This is the BRP plug-in Maptuner NANO, part number 01-NB3A, not the universal Nano HDMI version.
On 2019-onwards Sea-Doo models, the BRP Diagnostic Port Expansion Harness 01-MT067 is required when using the NANO alongside BRP accessory modules. This harness is sold separately.
