Jetting Maxter KZ / ICC Kart 1.8

The application offers a comprehensive solution for optimizing carburetor jetting based on various parameters, including temperature, altitude, humidity, atmospheric pressure, and specific engine configurations (engine model, floats, carb bore, emulsion tube type, oil ratio, fuel type). It provides 12 optimal carburetor configurations suited for KZ / KZ2 / ICC Maxter MXO, MXV, MXE, MXS, and MXS2 engines equipped with DellOrto VHSH 30 carbs.

It can automatically acquire positional data and altitude to obtain real-time temperature, pressure, and humidity from the nearest weather station over the Internet. For devices with an internal barometer, enhanced precision is achievable. Notably, this application can operate without GPS, Wi-Fi, or Internet connectivity; in such instances, users must input weather data manually.

• 12 distinct carburetor configurations available.
• For each configuration, the app provides detailed specifications including: main jet, emulsion tube, needle type and position (along with intermediate positions), throttle valve, idle jet (outer pilot jet), idle emulsifier (inner pilot jet), and air screw position.
• Extensive fine-tuning capabilities for all parameters.
• Custom carburetor creation functionality with over 90 needle options.
• History tracking of all jetting setups.
• Graphical representation of fuel mix quality (Air/Flow Ratio or Lambda).
• Support for two types of idle emulsion tubes (DP or DQ).
• Select from varying throttle valve sizes.
• Options for different fuel types (gasoline with or without ethanol and various racing fuels such as VP C12, VP 110, VP MRX02).
• Adjustable fuel/oil ratio settings.
• A wide selection of floats available.
• Float height adjustment options.
• A mix wizard to calculate the ideal fuel mixture ratio.
• Carburetor icing warnings included.
• Ability to utilize automatic weather data or connect to a portable weather station.
• Supports various measurement units: ºC and ºF for temperature; meters and feet for altitude; liters, ml, gallons, oz for fuel; mb, hPa, mmHg, inHg atm for pressure readings.

The application is structured into five main tabs:

• Results: This section displays the 12 different carburetor configurations based on users' specified weather conditions and engine parameters. Each setup includes vital values such as main jet and needle specifications among others. Additionally, users can fine-tune these settings while accessing data on air density and SAE-dyno correction factors through graphical representations of the air-fuel ratio.
• History: A dedicated space for reviewing all previous jetting setups.
• Compare: Users can compare two different carburetor configurations by inputting their components. Results are presented graphically showing the air-fuel ratio for both systems.
• Engine: Here users can configure essential engine information such as model type (MXO, MXV, MXE, MXS, MXS2), carburetor diameter and parameters affecting jetting setups based on their specific configurations.
• Weather: This tab allows users to set current temperature, pressure, altitude, and humidity values. Users can leverage GPS to acquire geographical data or opt for an external weather service. The app also checks for a built-in pressure sensor on the device to enhance accuracy.
