• New type of fuels have been added: VP Racing C12, VP Racing 110, VP Racing MRX02 • Added new feature: get weather (temperature, pressure, humidity) via Bluetooth using weather stations: Kestrel DROP, Kestrel 5x00, WeatherFlow WEATHERmeter, Skywatch BL • Added new feature: added the ability to calibrate the barometer built into your phone or tablet (go to the “Settings“ tab, then “Measurement units“) • Added new feature: added various utilities (unit converters) (go to the “Settings“ tab, then “Utils“) • We have improved our weather calculator significantly. Now you can manually select which type of atmospheric pressure you are working with (for example if you use portable barometers, weather stations): - sea level pressure QNH - sea level pressure QFF - station pressure (barometric pressure) • On the results tab, click on the drop-down menu 'Weather (AirLab)', new data for tuners are available: Air Density, Relative Air Density, Density Altitude, Station Pressure, SAE - Dyno Correction Factor, SAE - Relative Horsepower, Volumetric Content Of Oxygen, Oxygen Pressure • Improved functionality for the feature 'Weather for custom location'. We added a search bar where you can enter the location name. Search places easier and faster now • We added new fuels, this is gasoline with ethanol. It require a richer carburation than regular premium gasoline • Improved functionality and accuracy of fuel calculator • Bug fixes for 'share setup with friends' feature • Fixes for showing 'Carburetor icing alert', now it doesn't overlap other content • We reworked the altitude determination algorithm for the 'weather for custom location' feature. We hope that now, if you manually selected your location, the altitude will be calculated with much greater accuracy
MoreJetting supports Honda CRF150R, CRF250R, CRF250X, CRF450R, and CRF450X models manufactured between 2002 and 2021.
Jetting can automatically obtain weather data from the nearest weather station via the internet using GPS. It can also use an internal barometer on supported devices or accept manual input from a portable weather station or user entry.
Yes, Jetting can run without GPS, WiFi, or internet. In this mode, you will need to manually input the current weather data (temperature, altitude, humidity, atmospheric pressure).
Jetting provides recommendations for main jet, needle type, needle position, pilot jet, air screw position, and spark plug. It also allows for fine-tuning of these values.
Yes, Jetting supports selectable fuel types including gasoline with or without ethanol, and various racing fuels like VP Racing T4, U4.4, MR12, Sunoco 260 GT Plus, and EX02.
Jetting features a History tab where all your carburetor setups are saved. This includes new setups saved when you change weather, engine configuration, or fine-tuning adjustments. You can also save favorite settings here.
Jetting supports various units of measurement, including ºC and ºF for temperature, meters and feet for altitude, liters, ml, gallons, and oz for fuel, and mb, hPa, mmHg, inHg, and atm for pressure.
While Jetting provides detailed technical information, its user-friendly interface and automatic data fetching make it accessible for enthusiasts looking to optimize their bike's performance. The fine-tuning options cater to those seeking advanced adjustments.
