Custom ECU tuning for the 2025 Sea-Doo RXT-X 325, calibrated by Lukos Engineering. The RXT-X is the big open-water machine in the Sea-Doo line, and a machine-specific calibration is how its delivery gets sharper and more consistent - built from your craft's data rather than a generic file. Two routes: tune with the tuning device included, or tune only if you already run compatible hardware.
Confirm your craft is the 2025 RXT-X 325 before ordering and mention any modifications so the calibration reflects them. Recent Sea-Doo ECUs can require an unlocking step before calibration - check the requirements for your craft with us before ordering so the process is planned end to end. Tune-only assumes compatible hardware you already own.

Many of the products we sell are made to order, imported or custom built, so a lead time may apply. If you need a part urgently, contact us before ordering and we will confirm the expected delivery timeframe and process.
Some 2025 Sea-Doo ECUs require an unlocking step before tuning. Check with us for your exact craft before ordering and we will plan the full process.
Tune-only suits owners already running compatible tuning hardware; otherwise choose the option with the device included.
Confirm the craft, plan the ECU step, and get a calibration built for your RXT-X rather than everyone's.
Use the checked vehicle route, then confirm model year, engine, drivetrain, hardware and existing modifications on the product page or with our team before you commit.
Send us your vehicle, year, current setup and any fitting date, event, trip or deadline before ordering. We will help check fitment, product choice and timing.
