| Application | Sea-Doo RXT-X 325, 2025 |
| Options | Tune + device; tune only |
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.

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.
