Rotax MAX Jetting 2.1.2 [free]

The Rotax MAX Jetting App enables the user to calculate the optimal carburetor main jet size for Rotax kart engines of the MAX series:
- 125 Micro MAX evo
- 125 Mini MAX evo
- 125 Junior MAX evo
- 125 Senior MAX evo
- 125 MAX DD2
based on the current ambient conditions
- Temperature
- Altitude
- Air pressure
- Humidity
This can be done either automatically using GPS and a functioning internet connection or manually by entering the ambient parameters.
*Automatically*
Click on Use GPS position for weather data, select the desired engine type from the scroll menu and start the calculation tabbing the Calculate button.
*Manually*
Enter all ambient parameters, select the desired engine type from the scroll menu and start the calculation tabbing the Calculate button.
Important: Since the calculation is based on the "relative air pressure" (air pressure at 0m above sea level), your own barometer must be calibrated to the current altitude
before you can actually use the value. Online weather services provide this value by default.
To toggle between Celsius and Fahrenheit, press °C/°F and to choose between meters and feet press m/ft next to the entry of the value.
To start a new calculation, click "Reset".
