Internal barometer is used on supported devices for better precision. Application can run without GPS, WiFi and internet, in this case user has to enter weather data manually.

• For Mini, Junior, Max, DD2 you can choose which cylinder you are using. At the Grand Finals 2016, the cylinders for the Mini and Junior classes were updated. At the Grand Finals 2017, the cylinders for classes Max and DD2 were updated. New cylinders require richer carburation
• Two different tuning modes: "By regulations" and "Freestyle"!
• In first mode, the following values are given: main jet, spark plug, spark plug gap, needle type and position (including intermediate positions with washer), air screw position, idle screw position, optimal water temp, gear oil recommendation
• In second mode (Freestyle), the following values are given: main jet, spark plug, emulsion tube, needle, needle type and position (including intermediate positions with washer), throttle valve, idle jet (outer pilot jet), idle emulsifier (inner pilot jet), air screw position

• Selectable fuel type (VP MS93, gasoline with or without ethanol)
• Adjustable fuel/oil ratio
• Adjustable floats height
• Mix wizard to get the perfect mix ratio (fuel calculator)
• Carburetor ice warning
• Possibility of use automatic weather data or a portable weather station

• let you use different measure units: ºC y ºF for temperatures; meter and feet for altitude; liters, ml, gallons, oz for fuel; mb, hPa, mmHg, inHg for pressures

The application contains four tabs, which are described next:

• Results: In this tab two jetting setups are shown ('By regulation' and 'Freestyle'). These data are calculated depending on the weather conditions and the engine and track configuration given in the next tabs.
  Also this tab lets do a fine tuning adjustment for all values for each carburetor setup to adapt to the concrete engine.
  Besides this jetting information, the air density, density altitude, relative air density, SAE - dyno correction factor, station pressure, SAE- relative horsepower, volumetric content of oxygen, oxygen pressure are shown too.
  You can also see in a graphic form the calculated ratio of A/F (air and fuel) or Lambda.

• History: This tab contains the history of all jetting setups. If you change the weather, or engine setup, or fine tuning, the new setup will be saved in history.

• Engine: You can configure in this screen the information about the engine, that is, engine model, spark plug manufacturer, float type and height, fuel type, oil mix ratio and type of the track.
