The throttle body controls how much air enters the Rotax engine. So that the control unit knows the throttle position exactly, it has to be relearned under certain circumstances. You can carry out this throttle body adaptation yourself with the M-JET DIAGNOSTIC.
What is a throttle body adaptation?
During adaptation, the engine control module relearns the exact end positions and the zero point of the throttle body. This keeps idle, throttle response and control behaviour clean and reproducible.
When it is needed
- After cleaning or replacing the throttle body unit
- After work on the intake system
- With a rough idle or delayed throttle response
- After clearing certain fault codes
How the adaptation works
Plug in the dongle, open the app, connect the vehicle via Bluetooth and start the throttle body adaptation in the service section. The app guides you through the process. It is important that the engine is at the specified operating temperature and that the power supply is stable.
Tip for supercharged engines
If you have tuned your Sea-Doo with the M-JET Flasher, a clean adaptation is an extra benefit, because throttle response and control behaviour then match the adjusted software perfectly.
For all Rotax platforms
Whether Sea-Doo, Ski-Doo, Lynx or a jet boat with a BRP Rotax engine: the adaptation follows the same principle everywhere, because the control-unit base is identical.
Conclusion
The throttle body adaptation is a typical workshop job that you can handle yourself with M-JET DIAGNOSTIC, with no appointment and no waiting.
