1984-2007 models
This app is using temperature, altitude, humidity, atmospheric pressure and your engine configuration for calculate optimal jetting (carburetor configuration) and spark plug to use for Honda CR 2-strokes MX, Enduro 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. 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 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)
• 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 1984 to 2007:
• CR80R
• CR80RB
• CR85R
• CR85RB
• CR125R
• CR250R
• CR500R
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 setups. 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.
If you have any doubt about using this App, please, contact us. We answer every question, and we take care of all comments from our users to try to improve our software. We are also users of this application.}

Additional Information

Jan 22, 2025
• Добавлена новая функция: получение информации о погоде (температура, давление, влажность) через Bluetooth с помощью метеостанций: Kestrel DROP, Kestrel 5x00, WeatherFlow WEATHERmeter, Skywatch BL.
• Добавлена новая функция: добавлена возможность калибровки барометра, встроенного в ваш телефон или планшет (перейдите на вкладку «Настройки», затем «Единицы измерения»).
• Добавлена новая функция: добавлены различные утилиты (конвертеры единиц) (перейдите на вкладку «Настройки», затем «Утилиты»).
• Мы значительно улучшили наш погодный калькулятор. Теперь вы можете вручную выбрать, с каким типом атмосферного давления вы работаете (например, если вы используете портативные барометры, метеостанции):
- давление на уровне моря QNH
- давление на уровне моря QFF
- станционное давление (барометрическое давление)
• Мы добавили новые конфигурации карбюраторов для двигателей объемом более 100 куб.см, если в карбюраторе используется стандартный дроссельный клапан размера 6,5. Вы можете найти новые модели на вкладке «Двигатель», просто нажмите на список моделей
• Добавлен новый тип топлива: VP Racing C12, VP Racing 110, VP Racing MRX02
• На вкладке результатов нажмите в раскрывающемся меню «Погода (AirLab)», появятся новые данные для тюнеров: Плотность воздуха, Относительная плотность воздуха, Плотность высоты, Давление станции, SAE - Коэффициент коррекции динамо, SAE - Относительная мощность , Объемное содержание кислорода, давление кислорода
• Улучшена функциональность для функции «Погода для пользовательского местоположения». Мы добавили строку поиска, где вы можете ввести название места. Поиск мест теперь проще и быстрее
• Мы добавили новое топливо, это бензин с этанолом. Требует более насыщенной карбюрации, чем обычный бензин премиум-класса
• Улучшена функциональность и точность калькулятора топлива
• Исправлены ошибки для функции «поделиться настройками с друзьями»
• Исправлено отображение предупреждения об обледенении карбюратора, теперь оно не перекрывает другой контент
• Мы переработали алгоритм определения высоты для функции «погода для пользовательского местоположения». Мы надеемся, что теперь, если вы вручную выбрали свое местоположение, высота будет рассчитываться с гораздо большей точностью

• 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)
• We added new carburetor configurations for engines over 100cc if you use a stock throttle valve size 6.5 in carburetor. You can find new models on the «Engine», tab, just tap on the list of models
• New type of fuels have been added: VP Racing C12, VP Racing 110, VP Racing MRX02
• 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
