Jetting Modena OK & OK-J Kart

This app provides, using temperature, altitude, humidity, atmospheric pressure and your engine configuration, a recommendation about optimal carburetor config (jetting) for karts with Modena OK & OK-Junior engines (ME-K and ME-KJ models) which use a Tillotson diaphragm carburetors

Valid for the following Modena engine models:

• ME-KJ (Tillotson HC-114a, HC-116a, HW-43a, HW-43-CNC carburetor)
• ME-K (Tillotson HC-115a, HC-117a, HW-112a carburetor)

This app can obtain automatically the position and altitude to get the temperature, pressure and humidity from the nearest weather station through the internet. Internal barometer is used on supported devices for better precision. Application can run without GPS, WiFi and internet, in this case the user has to enter weather data manually.

• For each carburetor configuration, the following values are given: high speed screw position, low speed screw position, pop-off pressure, gasket & membrane reccomendation, spark plug, optimal exhaust temperature (EGT)
• Fine tuning for high and low speed screws
• History of all your carburetor configs
• Graphic display of fuel mix quality (Air/Flow Ratio or Lambda)
• Selectable fuel type (gasoline with or without ethanol, Racing fuels available, for example: VP Racing, Sunoco, Panta Kart Ron 102)
• 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 config 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 high speed screw position, low speed screw position, pop-off pressure, gasket & membrane reccomendation, spark plug, optimal exhaust temperature (EGT) 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. Also the air density, density altitude, relative air density, SAE - dyno correction factor, station pressure, SAE
