Jetting LKE KZ1 / KZ2 Kart 1.8

This application utilizes a combination of temperature, altitude, humidity, atmospheric pressure, and specified engine configurations—including engine model, floats, carb bore, emulsion tube type, floats, oil ratio, and fuel type—to offer tailored jetting recommendations. Notably, it presents optimal carburetor configurations for LKE TS1, LZ1 LKZ1, and BLACK ROCK engines equipped with Dell'Orto VHSH 30 carbs designed for KZ1 / KZ2 / ICC classifications.

Automated positioning features allow the app to retrieve local weather conditions via the internet, ensuring accurate values for temperature, pressure, and humidity. For devices that support internal barometers, enhanced precision is achievable. The application remains functional without GPS or internet connectivity; however, manual entry of weather data is required in such cases.

• 12 distinct carburetor configurations available.
• Each configuration details components such as main jet, emulsion tube, needle type and position (including intermediate settings), throttle valve, idle jet (outer pilot jet), idle emulsifier (inner pilot jet), and air screw position.
• Precision tuning capabilities for all values.
• Create custom carburetor setups from a selection of over 90 needles.
• Historical records of all carburetor configurations maintained.
• Graphical representation of fuel mix quality (Air/Flow Ratio or Lambda).
• Supports two idle emulsion tube types (DP or DQ).
• Select throttle valve size and fuel type (options include gasoline with or without ethanol as well as racing fuels such as VP C12, VP 110, VP MRX02).
• Adjustable fuel/oil ratio settings.
• A wide variety of float options with adjustable heights.
• Mix wizard for optimal mix ratio calculations.
• Carburetor ice warning feature.
• Automatic weather data retrieval or compatibility with portable weather stations.
• Flexible measurement units for temperature (ºC and ºF), altitude (meters and feet), fuel (liters, ml, gallons, oz), and pressure (mb, hPa, mmHg, inHg atm).

The application comprises five primary tabs:

1. Results: This section displays the twelve carburetor configurations calculated based on current weather conditions alongside the given engine and racetrack specifications. Each configuration includes values for the main jet, emulsion tube type, needle type and positioning, idle emulsifier, idle jet, throttle valve settings, air screw position, and additional metrics such as air density and volumetric oxygen content. A graphical representation of the air-fuel ratio (lambda) is also available.
2. History: This tab maintains a comprehensive record of all previous jetting setups.
3. Compare: Users can compare two carburetors by inputting components specific to each model. The comparative results are presented graphically as air-fuel ratios.
4. Engine: Users can configure engine-specific details including model (TS1, LZ1 LKZ1, BLACK ROCK), carburetor diameter and type, float specifications and height, fuel type and oil mix ratio. Jetting configurations adapt according to these parameters.
5. Weather: This section enables users to input current temperature, pressure, altitude, and humidity values while also supporting GPS functionality to acquire real-time data from the nearest weather station. Furthermore, it can leverage built-in pressure sensors in supported devices with an option to enable or disable this feature.
