Sea-Doo ECU Tune (2016-2024) - RXP-X, RXT-X, GTX, GTR & GTI Reflash
Sea-Doo ECU Tuning (2016–2024) by Cabrera Motorsports
From the RXP-X 300 to the GTI 130, every 2016–2024 Sea-Doo runs the same family of ECU, and every one of them leaves performance locked behind factory speed limiters, throttle delays, and conservative fueling. A CMS custom tune removes those limits with no engine work required, calibrated for your exact model and engine.
➕ What a CMS Sea-Doo Tune Does
- Factory speed limiter removed. Ride to your ski's true top speed instead of the factory cap.
- Sharper throttle response. Factory throttle delays and torque limiters are eliminated for instant response off the line.
- Optimized fueling and RPM limits. Calibrated for 93 octane pump gas and your setup, stock or modified.
We ride and race these exact setups on our own builds. We race what we sell!
🏄 Models We Tune (2016–2024)
RXP-X 300 & RXT-X 300
The supercharged 1630 ACE 300 is where a tune pays off the most. Stock or with intake, intercooler, and supercharger upgrades, the calibration is built around your parts list. Tell us your modifications in the configurator.
GTX 300, GTX 230 & GTR 230
Same supercharged platform in a touring or sport hull. A tune wakes up the GTX Limited 300, GTX 230, and GTR 230 whether you ride solo or loaded for a long day.
GTI 130, GTI 170 & GTX 170
The naturally aspirated 1630 ACE 170 and 1503 130 respond well to a calibration. For a stock ski, a tune is the best dollar-for-dollar upgrade you can make before touching the pump or intake.
Have a Sea-Doo Spark or a 2024+ 325 hp model? Those run different ECUs and have their own pages.
⛽ Fuel Requirement
All 2016–2024 Sea-Doo tunes are calibrated for 93 octane pump gas. No race fuel required. Fill up at the pump and ride.

❓ FAQs
Do you tune modified engines?
Yes. The configurator asks whether your engine is stock or has internal modifications, and the calibration is built for your actual setup.
How much faster will my Sea-Doo be?
Real-world results depend on your ski's condition, load, and water conditions, so we don't promise a specific number. We calibrate each tune to get the most out of your ski safely on 93 octane.
Can I go back to stock?
Yes. With the RTD your stock calibration is backed up and you can restore it anytime. Mail-in customers can request a return to stock.
Is my warranty affected?
ECU modifications can affect factory warranty coverage. Most of our customers are past warranty or accept the trade for the performance.
