Yamaha SuperJet ECU Tune - Stand-Up Reflash (2021+)
Yamaha SuperJet ECU Tuning by Cabrera Motorsports
The 2021+ SuperJet brought the stand-up into the four-stroke era with the TR-1 1,049cc engine, and the factory calibration leaves real performance locked away. A CMS custom tune opens it up with no engine work required. Stand-up is our home turf. We race these skis, and the same calibration work that goes into our race program goes into your tune.

➕ What a CMS SuperJet Tune Does
- Factory speed limiter removed. Ride to the SuperJet's true potential instead of the factory cap.
- Sharper throttle response. Factory throttle delays and torque limiters are eliminated for instant response, exactly what you want on a stand-up.
- Optimized fueling and RPM limits. Calibrated for your fuel and your setup, stock or modified.
We ride and race these exact setups on our own builds. We race what we sell!
🏄 Which SuperJet Can Be Tuned?
| Model | Engine | ECU tuning |
|---|---|---|
| SuperJet 2021+ | TR-1 1,049cc four-stroke | Yes. RTD wireless or mail-in reflash |
| SuperJet 701 (1990–2020) | 701cc two-stroke, carbureted | No ECU to tune. See our Yamaha Vintage Legends parts instead |
The TR-1 platform is shared with the Yamaha EX and the JetBlaster, so the tuning process is proven across thousands of engines.
⛽ Fuel Options
93 octane pump gas is the right tune for most riders. Fill up at any station and ride. For race builds, we also calibrate for AVGAS, VP MS109, VP MS103, and Ignite E85 race fuels. Select your fuel in the configurator.

❓ FAQs
Can you tune my 701 SuperJet?
No. The 701 is a carbureted two-stroke with no ECU, so there is nothing to flash. For the 701 we carry pipes, heads, and handling parts in our Yamaha Vintage Legends collection.
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 SuperJet 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 your chosen fuel.
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.
