1998-2020 modelsThis app is using temperature, altitude, humidity, atmospheric pressure and your engine configuration for calculate optimal jetting (carburetor configuration) and spark plug to use for KTM 2-strokes MX, Enduro and Freeride bikes (SX, SXS, XC, XC-W, EXC, MXC, R models).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. If more accuracy is needed, a portable weather station can also be used. Application can run without GPS, WiFi and internet, in this case user has to give the weather data manually.For each carburetor configuration, the following values are given: main jet, needle type, needle position, pilot jet, air screw position, throttle valve size, spark plugFine tuning for all these valuesHistory of all your jetting setupsGraphic display of fuel mix quality (Air/Flow Ratio or Lambda)Selectable fuel type (gasoline with or without ethanol, Racing fuels available, for example: VP C12, VP 110, VP MRX02, Sunoco)Adjustable fuel/oil ratioMix wizard to get the perfect mix ratio (fuel calculator)Carburetor ice warningPossibility of use automatic weather data or a portable weather stationIf 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 placelet you use different measure units: C y F for temperatures, meter and feet for altitude, liters, ml, gallons, oz for fuel, and mb, hPa, mmHg, inHg atm for pressuresValid for the following 2T models from 1998 to 2020:50 SX50 SX Mini50 Supermoto60 SX65 SX65 XC85 SX105 SX125 SX125 SXS125 EXC125 XC-W125 MXC125 EXE125 Supermoto144 SX150 SX150 XC150 XC-W200 SX200 EXC200 XC200 MXC200 EGS200 XC-W250 SX250 SXS250 XC250 XC-W250 EXC300 EXC300 XC300 XC-W300 MXC380 SX380 EXC380 MXCFreeride 250 RThe application contains four tabs, which are described next:Results: In this tab main jet, needle type, needle position, pilot jet, air screw position, throttle valve, spark plug 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.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 setups.This tab also contains your favorite carburetor configs.Engine: You can configure in this screen the information about the engine, that is, engine model, year, spark manufacturer, fuel type, oil mix ratio.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 enable alerts about possible carburetor icing.If you have any doubt about using this App, please, contact us.
