Jetting Vortex KZ1 / KZ2 Kart 2.3

This application provides 12 jetting recommendations for Vortex RTZ, RSZ, RKZ, RVZ, RVXX, RVX, RVS engines equipped with Dell'Orto VHSH 30 carburetors based on temperature, altitude, humidity, atmospheric pressure, and engine configuration details.

The app can automatically retrieve temperature, pressure, and humidity data from the nearest weather station via the internet by obtaining the user's location and altitude. For improved precision, devices with internal barometers are supported. In cases where GPS, WiFi, and internet are unavailable, users can manually input weather information.

• 12 different jetting setups
• Comprehensive values provided for each jetting setup including main jet size, emulsion tube type, needle type and position (including intermediate positions with washers), throttle valve size, idle jet (outer pilot jet), idle emulsifier (inner pilot jet), and air screw position
• Fine-tuning options available for all parameters
• Custom carburetor creation with over 90 needle options for performance checking
• History log of all previous jetting setups
• Visual representation of fuel mixture quality in Air/Flow Ratio or Lambda values
• Support for two idle emulsion tube types (DP or DQ)
• Selectable throttle valve sizes and fuel types including gasoline variations and racing fuels like VP C12, VP 110, VP MRX02
• Adjustable fuel/oil ratio settings
• Diverse options for floats selection and adjustable floats height
• Mix wizard feature for precise mix ratio calculation (fuel calculator)
• Carburetor ice warning alert
• Options to use automatic weather data or a portable weather station
• Conversion between various measurement units including temperature (ºC and ºF), altitude (meters and feet), fuel volume (liters, ml, gallons, oz), and atmospheric pressure (mb, hPa, mmHg, inHg, atm)

The application interface is organized into five tabs:

1. Results: Provides 12 jetting setups tailored to specific conditions and engine configurations with detailed values for main jet size, emulsion tube type, needle specifics, pilot jets, throttle valve settings, and air screw position. Users can fine-tune parameters to optimize performance.
Additional data such as air density calculations, SAE - dyno correction factors, oxygen pressure details are also displayed along with a graphical representation of the air/fuel ratio.
2. History: A log of all previous jetting setups.
Compare: Allows users to compare two carburetors by setting all components to visualize differences in air/fuel ratios through graphs. Engine: Offers customization options for engine specifics like model, carburetor details, float configurations, fuel type, oil mix ratio, etc., which influence the recommended jetting setups. Weather: Enables users to input current weather data or retrieve it using GPS positioning or external sources. Users can utilize a built-in pressure sensor on compatible devices for added accuracy.
