A willing response when you open the throttle makes time on your GTR 230 more enjoyable. Our Sea-Doo GTR 230 ECU remap for 2025 uses your craft's data and feedback to refine the calibration for its fuel and fitted parts.
Custom tuning for the response you enjoy
A more willing response is something you can appreciate throughout a ride. We develop the calibration for your own GTR 230, using its fuel, fitted parts and data together with your feedback. That gives the tuning a purpose you can feel when you get back on the water.
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.
Choose your tuning option
Both options require the send-in MG1 ECU unlock before calibration. The unlock-and-licensing service includes four HP Tuners credits.

MG1 ECU unlock before remote tuning
The MG1 ECU must be sent in for unlocking before calibration. The unlock-and-licensing service includes four HP Tuners credits. We arrange that step with you, then guide the remote tune using the equipment in your selected package.
How remote tuning works
With the required send-in MG1 unlock complete, your craft can stay with you for the guided remote calibration. 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

Frequently asked questions
Does the ECU need unlocking first?
Yes. The MG1 unlock must be completed before the calibration can be applied. The ECU is sent in for that procedure; we arrange the sequence with you.
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.
