This app provides, using temperature, altitude, humidity, atmospheric pressure and your engine configuration, a recommendation about optimal carburetor configuration (JETTING) and spark plug to use for karts with Briggs & Stratton LO206 (local option) karting engines, which use a Walbro PZ22 carburetor.
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.
• Two different tuning modes: "Free jet sizes" and "Fixed (Stock) jet sizes"
• In first mode, the following calculated values are given: main jet size, needle type, needle position, pilot (idle) jet, mixture screw position, spark plug, spark plug gap, float height
• In next mode, the sizes of main jet and idle jet always remain unchanged (Stock), and the mixture quality is controlled by the height of the floats and position of the needle
• Fine tuning for these values
• History of all your carburetor configurations
• Graphic display of fuel mix quality (Air/Flow Ratio or Lambda)
• Selectable fuel type (gasoline with or without ethanol, methanol, Racing fuels available, for example: VP C12, VP 110, VP MRX02)
• Adjustable fuel/oil ratio
• Mix wizard to get the perfect mix ratio (fuel calculator)
• Carburetor ice warning
• Possibility of use automatic weather data or a portable weather station
• If you don't want to share your location, you can manually select any place in the world, the carburetor setups will be adapted for this place
• 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 for pressures
The application contains four tabs, which are described next:
• Results: In this tab main jet, needle type, needle position, pilot jet, mixture screw position, spark plug, spark plug gap, float height are shown. These data are calculated depending on the weather conditions and the engine configuration given in the next tabs.
This tab lets do a fine tuning adjustment for all this values 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.
On this tab, you can also share your settings with your colleagues, or add settings to your favorites.
You can also see in a graphic form the calculated ratio of air and fuel (lambda).
• History: This tab contains the history of all carburetor configs.
• Engine: You can configure in this screen the information about the engine, that is, engine model, year, spark manufacturer, fuel type.
• 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 (temperature, pressure and humidity).
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.
Also, on this tab, you can manually select any place in the world, the carburetor setups will be adapted for this place.
