This app provides, using temperature, altitude, humidity, atmospheric pressure and a given engine configuration (engine model, floats, carb bore, emulsion tube type, floats, oil ratio, fuel type), jetting recommendations (12!!! optimal carburetor configurations) for KZ / KZ2 / ICC Maxter MXO, MXV, MXE, MXS, MXS2 engines that have DellOrto VHSH 30 carbs.
This app can obtain automatically the position and altitude to get the temperature, pressure and humidity from the nearest weather station thought internet. 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.
• 12 different carburetor configs!
• For each carburetor configuration the following values are given: main jet, emulsion tube, needle type and position (including intermediate positions with washer), throttle valve, idle jet (outer pilot jet), idle emulsifier (inner pilot jet), air screw position
• Fine tuning for all these values
• You can create your carburetor and check the performance (over 90 needles available)
• History of all your jetting setups
• Graphic display of fuel mix quality (Air/Flow Ratio or Lambda)
• Support two idle emulsion tube types (DP or DQ)
• Selectable throttle valve Size
• Selectable fuel type (gasoline with or without ethanol, Racing fuels available, for example: VP C12, VP 110, VP MRX02)
• Adjustable fuel/oil ratio
• large selection of floats
• 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, and mb, hPa, mmHg, inHg atm for pressures.
The application contains five tabs, which are described next:
• Results: In this tab, 12 different carburetor configs are shown. These data are calculated depending on the weather conditions and the engine and track configuration given in the next tabs. For each jetting setup, the following values are given: main jet, emulsion tube, needle type and needle position, idle emulsifier, idle jet, throttle valve, air screw position.
This tab lets do a fine tuning adjustment for all this values for each jetting 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, oxygen pressure and volumetric content of oxygen are shown too.
You can also see in a graphic form the calculated ratio of air and fuel (lambda).
• History: This tab contains the history of all jetting setups.
• Compare: On this tab, you can compare two carburetors. To do this, you need to set all the components of the carburetor. The result will be shown in the form of graphs of the ratio of air and fuel (or lambda).
• Engine: You can configure in this screen the information about the engine, that is, engine model (MXO, MXV, MXE, MXS, MXS2), carburetor diameter, emulsion tube type, float type and height, fuel type, oil mix ratio and type of the circuit. Depending of this parameters, the jetting setups will be adapted.
• Weather: In this tab, you can set the values for current temperature, pressure, altitude and humidity.
Also this tab allows to use the GPS to get the current position and altitude, and connect to an external service (you can choose one weather data source from several possible) to get the weather conditions of the nearest weather station.
In addition, this application can work with a pressure sensor built into the iPhone. You can see if it is available on your device and turn it on or off.
If you have any doubt about using this App, please, contact us. We answer every question, and we take care of all comments from our users to try to improve our software.}

1.9
Jan 28, 2025
• Neue Funktion hinzugefügt: Wetter (Temperatur, Druck, Luftfeuchtigkeit) über Bluetooth mit Wetterstationen abrufen: Kestrel DROP, Kestrel 5x00, WeatherFlow WEATHERmeter, Skywatch BL
• Neue Funktion hinzugefügt: Möglichkeit hinzugefügt, das in Ihrem Telefon oder Tablet integrierte Barometer zu kalibrieren (gehen Sie auf die Registerkarte „Einstellungen“ und dann auf „Messeinheiten“)
• Neue Funktion hinzugefügt: verschiedene Dienstprogramme (Einheitenumrechner) hinzugefügt (gehen Sie auf die Registerkarte „Einstellungen“, dann auf „Dienstprogramme“)
• Wir haben unseren Wetterrechner erheblich verbessert. Jetzt können Sie manuell auswählen, mit welcher Art von Luftdruck Sie arbeiten (z. B. wenn Sie tragbare Barometer oder Wetterstationen verwenden):
- Meeresspiegeldruck QNH
- Meeresspiegeldruck QFF
- Stationsdruck (Luftdruck)
• Wir haben neue Kraftstoffe hinzugefügt, dies sind VP Racing C12, VP Racing 110, VP Racing MRX02, VP Racing MS93 und Benzin mit Ethanol. Es erfordert eine fettere oder magerere Vergasung als normales Premium-Benzin
• Wenn Sie jetzt keine Zwischenpositionen (halbe Schritte) für die Nadel sehen möchten, können Sie diese auf der Registerkarte "Motor" ausschalten
• Klicken Sie auf der Registerkarte Ergebnisse auf das Dropdown-Menü 'Wetter (AirLab)'. Es stehen neue Daten für Tuner zur Verfügung: Luftdichte, Relative Luftdichte, Dichte Höhe, Stationsdruck, SAE - Dyno-Korrekturfaktor, SAE - Relative Leistung , Volumetrischer Gehalt an Sauerstoff, Sauerstoffdruck
• Verbesserte Funktionalität für die Funktion "Wetter für benutzerdefinierten Standort". Wir haben eine Suchleiste hinzugefügt, in die Sie den Ortsnamen eingeben können. Suche Orte jetzt einfacher und schneller
• Wir haben den Algorithmus zur Höhenbestimmung für die Funktion "Wetter für benutzerdefinierten Standort" überarbeitet. Wir hoffen, dass jetzt, wenn Sie Ihren Standort manuell ausgewählt haben, die Höhe mit viel größerer Genauigkeit berechnet wird
• Fehlerbehebungen für die Funktion "Setup für Freunde freigeben"
1.8
Nov 01, 2021
• Added new feature: get weather (temperature, pressure, humidity) via Bluetooth using weather stations: Kestrel DROP, Kestrel 5x00, WeatherFlow WEATHERmeter, Skywatch BL
• Added new feature: added the ability to calibrate the barometer built into your phone or tablet (go to the “Settings“ tab, then “Measurement units“)
• Added new feature: added various utilities (unit converters) (go to the “Settings“ tab, then “Utils“)
• We have improved our weather calculator significantly. Now you can manually select which type of atmospheric pressure you are working with (for example if you use portable barometers, weather stations):
- sea level pressure QNH
- sea level pressure QFF
- station pressure (barometric pressure)
• We added new fuels, this is VP Racing C12, VP Racing 110, VP Racing MRX02, VP RACING MS93, and gasoline with ethanol. It require a richer or leaner carburation than regular premium gasoline
• Now, if you don’t want to see intermediate (half-steps) positions for the needle, you can turn it off on the 'Engine' tab
• On the results tab, click on the drop-down menu 'Weather (AirLab)', new data for tuners are available: Air Density, Relative Air Density, Density Altitude, Station Pressure, SAE - Dyno Correction Factor, SAE - Relative Horsepower, Volumetric Content Of Oxygen, Oxygen Pressure
• Improved functionality for the feature 'Weather for custom location'. We added a search bar where you can enter the location name. Search places easier and faster now
• We reworked the altitude determination algorithm for the 'weather for custom location' feature. We hope that now, if you manually selected your location, the altitude will be calculated with much greater accuracy
• Bug fixes for 'share setup with friends' feature
