Jetting Vortex ROK GP Kart 1.8

This application utilizes various environmental parameters—temperature, altitude, humidity, atmospheric pressure—and engine configuration to provide tailored recommendations for optimal carburetor settings (jetting) and spark plug selections for Vortex ROK engines, specifically the ROK MINI, ROK GP JUNIOR, and ROK GP SENIOR models, which utilize either a Dellorto VHSH 30 or PHBG 18 carburetor.

An automated feature allows the app to access location and altitude data to retrieve temperature, pressure, and humidity from the nearest weather station via the internet. For enhanced accuracy, supported devices can leverage an internal barometer. The application is functional offline; however, users must manually input weather data in the absence of GPS or internet connectivity.

• Two distinct tuning modes: "By regulations" and "Freestyle" modes.
• In "By regulations," users receive detailed specifications including: main jet, spark plug type, spark plug gap, needle type and position (including intermediate adjustments), air screw position, optimal water temperature, and gear oil recommendations.
• The "Freestyle" mode offers a broader range of parameters such as: main jet, spark plug, emulsion tube, needle settings (including intermediate positions), throttle valve size, idle jet configurations (outer and inner pilot jets), and air screw position.
• Comprehensive fine-tuning capabilities for all settings.
• A complete history log of previous carburetor configurations.
• Graphical representation of fuel mix quality, showcasing Air/Flow Ratio or Lambda.
• Selectable fuel types including various gasoline blends and racing fuels like VP C12, VP 110, VP MRX02, and Sunoco.
• Adjustable fuel/oil ratios and float heights.
• A mix wizard for precise fuel mixture calculations.
• Notification feature for potential carburetor icing conditions.
• Options for automatic weather data retrieval or manual location selection to receive tailored carburetor setups.
• Unit conversion flexibility for temperature (ºC/ºF), altitude (meters/feet), fuel volume (liters/milliliters/gallons/ounces), and pressure (mb/hPa/mmHg/inHg).

The application features four primary tabs:

• Results: This section presents configurations for both "By regulation" and "Freestyle" modes. Data is calculated based on specified weather conditions along with engine and track configurations. Fine-tuning options are available here as well as key metrics such as air density, density altitude, relative air density, SAE dyno correction factor, station pressure, SAE relative horsepower, volumetric oxygen content, and oxygen pressure. Users can also visualize the calculated air-fuel ratio graphically.
• History: This section logs all previously configured carburetor setups alongside favorites for easy access.
• Engine: Here, users can input pertinent engine information including model specifications, spark plug manufacturer details, float type and height adjustments, fuel selection, oil mixing ratio, and track type details.
• Weather: This tab enables users to enter current temperature, pressure, altitude, and humidity data. Users can opt to use GPS for real-time data gathering or connect to external weather services for localized conditions. Additionally, support for built-in pressure sensors is available on compatible devices. Alerts can also be activated for potential carburetor icing conditions.
