Jetting Sherco 2T Moto Bikes

2014-2022 models

This app is using temperature, altitude, humidity, atmospheric pressure and your engine configuration for calculate optimal jetting (carburetor config) and spark plug to use for Sherco 2-strokes Enduro, Motocross, Trial moto bikes.

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.
App 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 plug

Fine tuning for all these values

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 C12, VP 110, VP MRX02, Sunoco)

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 dont 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: C y F for temperatures, meter and feet for altitude, liters, ml, gallons, oz for fuel, and mb, hPa, mmHg, inHg for pressures

Valid for the following Sherco 2T models from 2014 to 2022:

The 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, 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 configurations.
If you change the weather, or engine setup, or fine tuning, the new setup will be saved in history.

This tab also contains your favorite settings.

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 manually select any place in the world, the carburetor setups will be adapted for this place.
