• Jetting for new 2020 Micro EVO and Mini EVO engines (model year 2020 or MY20) is available! You can select engine type: MICRO EVO 2020 or MINI EVO 2020 on the Engine tab! • We redesigned 'Engine' tab a bit. Now you can separately choose the engine class, and separately the year of manufacture of the cylinder • The upgrades in detail: The modified exhaust for both Micro MAX and Mini MAX is based on the original Micro package. An inlet insert (carburettor throttle body restrictor) makes the carburettor less sensitive to different settings in the carburetion. The Mini MAX will use the same smaller radiator as the Micro MAX does already • Engine temperature recommendations changed • For classes Mini, Junior, Max, DD2 you can now choose which cylinder you are using. At the Grand Finals 2016, the cylinders for the Mini and Junior classes were updated. At the Grand Finals 2017, the cylinders for classes Max and DD2 were updated. New cylinders (with new advanced cylinder manufacturing technology and ecu) require richer carburation • 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) • Now, if you don’t want to see intermediate (half-steps) positions for the needle, you can turn it off on the 'Engine' tab • New type of fuels have been added: VP Racing MS93 and 93 AKI with ethanol. Please check which fuel you are using • 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 • In the 'Results' tab, we added recommendations about spark plug gaps, positions for idle adjustment screw, optimal water temperature, gear oil recommendations • We have changed recommendations for height of the floats, please check height of the floats on 'Engine tab' • Improved functionality and accuracy of fuel calculator • Added new type of spark: NGK Rotax • 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 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 • We added the ability to leave text notes for each history in 'History' tab. To do this, open any History, enter edit mode and add a note • Now you can manually select the translation language. Application contains many special terms and sometimes translations that we offer are not always good. We are sorry. Now, if your phone (for example) in German, but you are unhappy with the translation you can switch to English (for example) only in this app (you don't have to change locale of device). You can find this feature on 'Engine' tab at the very bottom

New cylinders (with new advanced cylinder manufacturing technology and ecu) require richer carburation • Now, if you don’t want to see intermediate (half-steps) positions for the needle, you can turn it off on the 'Engine' tab • New type of fuels have been added: VP Racing MS93 and 93 AKI with ethanol. Please check which fuel you are using • 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 • In the 'Results' tab, we added recommendations about spark plug gaps, positions for idle adjustment screw, optimal water temperature, gear oil recommendations • We have changed recommendations for height of the floats, please check height of the floats on 'Engine tab' • Improved functionality and accuracy of fuel calculator • Bug fixes for "share setup with friends" feature • Added new type of spark: NGK Rotax • 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

• Many jetting recommendations have been revised for better performance. Therefore, we strongly recommend that you check the fine tuning sliders, you may need to change them • For the Micro class the size of main jet has dropped by almost 2 sizes.

• New feature: Weather for custom location. You can manually select any place in the world and the optimum carburation will be calculated for it (for altitude and current weather conditions in this place). If you plan go to a race in another city or to the mountains for example, you easily can pre-adjust the carburetor.

• improvements to calculate carburation and weather data, now we use approximation formulas, which is the same used by ASOS/AWOS-3 automated weather stations at US Airports. Improvements will be noticeable to users from high altitude places.

• simplified design • improvements to calculate carburation and weather data, now we use approximation formulas, which is the same used by ASOS/AWOS-3 automated weather stations at US Airports. Improvements will be noticeable to users from high altitude places.

• several minor bugs fixed

• changes in application description

• fixes for needle position in tuning mode
