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.
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.
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.
Both options require the send-in MG1 ECU unlock before calibration. The unlock-and-licensing service includes four HP Tuners credits.

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.
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.
