Enjoy more of your RXT-X on the water

A willing response when you open the throttle makes your RXT-X more enjoyable on open water. Our Sea-Doo RXT-X 325 ECU remap for 2025 uses your craft's data and feedback to refine power delivery for its fuel and fitted parts, through a guided remote tuning process.

Custom tuning for the way you ride

Tell us what you enjoy about the craft and where you would like its response to feel different. We use that feedback with the requested data to develop the calibration for your RXT-X. Choose the device-inclusive option if you need the tuning equipment, or Tune Only if you already own a compatible tool.

Our custom tunes include up to four revisions in the first 30 days, followed by log reviews at 3, 6 and 12 months. Your feedback helps us refine the calibration and check how your vehicle is running after you have had time to use it.

Physical upgrades for your vehicle

We also offer physical upgrades for most vehicles. If you're looking to take yours further, tell us what you have in mind. We can help you choose suitable parts and plan the tuning around them.

How remote tuning works

Remote tuning lets us work with you while the craft stays at your location. First, we confirm support for your vehicle and check its fitted hardware and the fuel you plan to use. We then guide you through reading and loading the calibration with the device. Send us the requested logs and your feedback so we can check the response and refine the tune.

Tune & Tuning Device includes the tuning device, required licence and delivery. You keep the device. Choose Tune Only when you already own compatible equipment.

Collect any requested data in a suitable, safe and lawful setting, following the tuner instructions. If a reading or a running concern needs attention, tell us before continuing so it can be assessed.

Get ready for your tune

Tell us the exact craft, fitted parts, intended fuel and any running concerns before tuning. Keep the hardware and fuel consistent during calibration. Speak to us before later changes that affect the tune; further calibration may be needed.

Tuning is a vehicle modification and can affect warranty cover. Discuss it with your insurer and warranty provider before the work.

Support after your custom tune

Once you have had a chance to ride, tell us how your craft feels. Our custom tunes include up to four revisions within 30 days, plus log reviews at 3, 6 and 12 months to check how everything is running.

Talk to us about your tune

Tell us about your Sea-Doo RXT-X 325, its fitted parts and what you would like from it. Get in touch with us and we will help you choose the right tuning route.

Frequently asked questions

Which option should I choose if I already own a device?

Tune Only is the route for an existing compatible device. Choose Tune & Tuning Device when you need the hardware supplied with the service.

What if I change parts after tuning?

Tell us before fitting parts that affect engine operation or fuelling. The calibration was developed for the current combination, so further tuning may be needed.

What support is included after the custom tune?

Up to four revisions within 30 days, followed by log reviews at 3, 6 and 12 months to check how everything is running.

Will it affect my warranty?

It can. Treat the tune as a vehicle modification and discuss cover with your warranty provider and insurer before the work.

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.

Fitment first

Model year, engine, drivetrain, hardware and existing modifications can all change what fits. Check the applications and supplier notes above, or send us your exact vehicle and setup before ordering.
