Jetting for Yamaha KT100 Kart at Mac App Store analyse

This app provides, for the current weather conditions and a given engine configuration (engine model, gas, etc.), a jetting recommendation for Yamaha KT100 engines. In order to get the weather values, the application can use the GPS to obtain the position and altitude, and the network connection to get the temperature, pressure and humidity from the nearest weather station. Nevertheless, the application can run without GPS and internet connection, in this case, the user has to give the weather data. The application is made up of four tabs that are described next. - Results: In this tab, a recommended jetting setup is shown. These data are calculated depending on the weather conditions and the engine and track configuration given in the following tabs. The following values are given: high needle, low needle, pop-off pressure and fulcrum arm height. Besides this jetting information, the air density and density altitude are shown too. In addition, this tab lets do a fine tunning adjustment for the high and low needles to adapt to the concrete engine. These values will be stored and used in the future sessions. - Weather: In the second tab, called Weather, you can set the values for current temperature, pressure, altitude and humidity. The values of this screen can be manually set or can be loaded by the application reading the data from the nearest weather station (from the GPS tab). - Engine: You must set in this screen the information about the engine, that is, the engine type (Tuned Pipe / long pipe, 4-hole and 3-hole can, junior with standard WB3A carb or junior with smaller WA55 carb), the oil mix ratio and the type of the circuit (sprint or enduro, short or long tracks). Depending of the track type, the jetting setups will be adapted. - GPS: This tab allows to use the GPS to get the current position and altitude, and connect to an external service to get the weather conditions of the nearest weather station (temperature, pressure and humidity). The application works with different measure units: inHg, mb, mmHg, hPa, atm for pressure, ºC and ºF for temperature.
