Jetting for TM Racing 2T Moto 2.0

2012-2020 models

This application utilizes temperature, altitude, humidity, atmospheric pressure, and your engine configuration to calculate the optimal jetting (carburetor configuration) and spark plug for TM Racing 2-strokes Enduro, Motocross, Supermoto motorcycles.

The app can automatically acquire the position and altitude to fetch the temperature, pressure, and humidity from the nearest weather station via the internet. For enhanced precision, supported devices utilize an internal barometer. Users have the option to use a portable weather station for even greater accuracy. In cases where GPS, WiFi, and internet are unavailable, the user can manually input weather data.

• For each carburetor configuration, the following values are provided: main jet, needle type, needle position, pilot jet, air screw position, throttle valve size, spark plug
• Fine-tuning capability for all aforementioned values
• History log of all carburetor configurations
• Graphic representation of fuel mix quality (Air/Flow Ratio or Lambda)
• Choice of fuel type including gasoline with or without ethanol, as well as Racing fuels like VP C12, VP 110, VP MRX02
• Adjustable fuel/oil ratio
• Mix wizard tool for perfect mix ratio calculation (fuel calculator)
• Carburetor ice warning feature
• Option to utilize automatic weather data or a portable weather station
• If location sharing is declined, users can manually select any place globally while the carburetor setups adjust accordingly.
• Diverse measurement unit selections: ºC and ºF for temperatures; meter and feet for altitude; liters, ml, gallons, oz for fuel; and mb, hPa, mmHg, inHg atm for pressures

Applicable to the following models from 2012 to 2020:

• MX 85
• MX 100
• MX 125
• EN 125
• MX 144
• EN 144

• The application is structured in four tabs as outlined below:

• - Results:

• In this tab, main jet, needle type, needle position, pilot jet, air screw position, throttle valve size, and spark plug details are displayed. These data are computed based on weather conditions and engine configuration set in subsequent tabs. Users can fine-tune these values to suit their specific engine. Additionally, air density calculations—such as density altitude and relative air density—are shown along with SAE-dyno correction factor, station pressure readings, SAE-relative horsepower figures, volumetric oxygen content details. Sharing settings with colleagues or adding them to favorites is supported on this tab. Users can visualize the calculated air-to-fuel ratio (lambda) graphically.

• - History:

• This tab archives all carburetor configurations. Modifications made to weather conditions or engine setups are saved in the history log. It also encompasses a section for favorite settings.

• - Engine:

• This screen allows users to input engine-specific information like model, year, spark plug manufacturer, fuel type used, and oil mix ratio.

• - Weather:

• In this tab, users can set current temperature values along with pressure levels and altitude. It offers GPS support to acquire real-time position and altitude data besides connecting to external services for weather updates from nearby stations. iPhone devices equipped with a pressure sensor can utilize it within this app. Users have the flexibility to manually select any global location for adjusted carburetor configurations. Additionally, alerts regarding potential carburetor icing can be activated.
