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 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) • 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 setups 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 atm for pressures Valid for the following 2T models from 2010 to 2023: • TC 50 • TC 50 Mini • TC 65 • TC 85 • TC 125 • TX 125 • CR 125 • CR 144 • TC 150 • TE 150 • TC 250 • TX 300 • TE 250 • TE 300 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. Moreover, on this tab, you can enable alerts about possible carburetor icing.

It takes a little bit of playing around to learn how to use it. But overall I’m super happy with it. ### 5/5 — Good *2020-01-06* It’s not info from manuals, it’s really works. Best jetting app ### 5/5 — Must have *2019-04-06* Took some fiddling around as jetting needed to be skewed quite a bit to match my setup, otherwise jetting now is very very consistent, a lot less guessing and fooling around with the engine. ### 5/5 — Must have *2019-04-04* I work as mechanic and this app saves for me a lot lot lot of time to setup carbs :) ### 5/5 — Must have *2019-03-31* Must have for beginners. ### 5/5 — Good *2019-03-20* I work as mechanic and this app saves for me a lot lot lot of time to setup carbs :) ### 5/5 — Good job *2019-03-18* Easy to use and very valuable information. ### 5/5 — Best *2019-03-10* Power feels great with base setups for my weather and location. ## Frequently asked questions about Jetting for Husqvarna 2T Moto ### What Husqvarna models does Jetting for Husqvarna 2T Moto support?
