About this app

This app provides, using weather conditions and your engine configuration, a recommendation about jetting and spark plug to use for karts with Rotax Max EVO (Senior, Minimax, Micromax, Supermax, DD2 or Junior), which use a Dellorto VHSB 34 XS carb to get the best performance.

In order to get the weather values, the application can use the GPS to obtain the position and altitude, and the network connection to get the temperature, pressure and humidity from the nearest weather station. Nevertheless, the application can run without GPS and internet connection, in this case, the user has to enter the weather data.

The application is made up of four tabs that are described next:

- Results: in this tab, the recommended main jet, needle position, air density and spark plug type values are shown. These data are calculated depending on the weather conditions and the configuration given in the other tabs. In addition, this tab lets to make a fine tuning adjustment to adapt to your concrete motor and carburetor.

- Weather: you can set the values for current temperature, altitude, pressure and humidity. The values of this screen can be manually set or can be loaded by the application reading the data from the nearest public weather station (from the GPS tab).

- Engine: you can set in this screen the information about your engine, carburator and track, that is, the FR125 engine type (Micromax, Minimax, Senior, Supermax, Junior or DD2), the model year, the spark plug brand used, the needle type, the float/pilot jet combo, the floats height, venturi (dell orto 12.5 or 8.5), oil mix ratio, airbox type (new or old model) and the track type.

- GPS: this tab allows to use the GPS to get the current position and altitude, and connect to an external service to get the weather conditions of the nearest weather station (temperature, pressure and humidity).


The application works with different measure units: inHg, mb, mmHg, hPa, atm for pressure, ºC and ºF for temperature.

If you click in "More from developer" you can find the other karting tools from ISEnet:
- Jetting Max Kart, for Rotax Max non-Evo engines (Rotax Max before 2015).
- Kart Chassis Setup, that helps you set up your chassis easily, for all brands: CRG, Tony Kart, Maranello, Birel, Intrepid, Energy, etc.
- Other carburation apps for go karts:
+ IAME X30 & Leopard
+ TM KZ / ICC / Shifter (K9, K9B, K9C, KZ10, KZ10B).
+ Honda CR125 powered shifter go-kart.
+ Modena KK1 & KK1R
+ IAME Shifter, Screamer & SuperShifter
+ Yamaha KT100.
- Air Density Meter: if you don't find a specific jotting app for your engine, you can use this app to create jeting charts.
- Apps for MX bikes (KTM, Honda CR & CRF, Yamaha YZ, Suzuki RM, Kawasaki KX).

The app is valid for RGMMC (Rotax Max Challenge) or SKUSA, but is not valid for Rotax Max FR125 before 2015. For them, you should install Jetting Max Kart.

We're working in new carburetion apps for other kart motors (LKE, Maxter, TKM, Vortex, WTP, etc.) and a new tech apps for Alfano / Mychron visualization. Please send us and email if you want to be notified when these tools are published.

ERRORS AND SUGGESTIONS:
Please understand that because of the variety of phones, android versions, etc. it's very hard to develop bug-free applications. If you find any bug, please, send us an email to android@isenet.es explaining, as detailed as you can, the error that you've detected. We'll try to fix it or give an answer as soon as possible.


PERMISSIONS:
The application needs the next permissions:
- Your location: it lets the application get the position and the altitude using the GPS to know which is the nearest weather station.
- Storage: it's used for storing the config preferences.
- Network communication: to invoke the external service which provides the current weather conditions
- Phone calls (read phone state and identity): it allows to get the system identifier in order to validate the license status of the installed application.
