Sea-Doo RXT-X 325 Tuning: Setup and Unlock for the 325 Platform
The Sea-Doo RXT-X 325 shares the Rotax 1630 ACE 325 base with the other 325 models, but it is designed as a touring-oriented craft with a focus on stability and long distances. For more performance, the same clean route via M-JET applies.
Unlock and Replacement ECU
The foundation is the ECU Unlock BRP Sea-Doo 325 for the Bosch MG1CA920 ECU. For models from 2024 onwards, the Sea-Doo 325 MG1 Unlock&Tune Replacement ECU is available as a prepared plug-and-play ECU, including data transfer via the M-JET DATA dongle.
Vmax and Display
If you first only want to release the top speed without touching the power, the M-JET Vmax Remover / GPS Lost for Sea-Doo 325 is the right solution, controlled entirely via the app and removable again. For monitoring while riding, the M-JET 325 AFR / Boost Module shows AFR or boost pressure directly in the stock cluster.
Hardware and Diagnostics
As further hardware from Stage 2, the Blow Off Valve Kit incl. Charge Air Hoses for Sea-Doo 325 is a good option. Before and after every change, the M-JET DIAGNOSTIC - Diagnostic Tool for BRP helps you keep an eye on fault codes and live values.
Conclusion
On the RXT-X 325, the combination of unlock, app-controlled modules, and targeted hardware delivers more performance without any workshop visit.
