This app provides, using temperature, altitude, humidity, atmospheric pressure and your engine configuration and fuel type, a recommendation about best jetting (carburetor configuration) and spark plug to use for Yamaha 2-strokes MX bikes (YZ and PW 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 setup, the following values are given: main jet, needle type, needle position, pilot jet, air screw position, throttle valve size, spark plug
• Fine tuning for all these values
• History of all your jetting setups
• 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 C12, VP 110, VP MRX02)
• Adjustable fuel/oil ratio
• Mix wizard to get the perfect mix ratio (fuel calculator)
