Technical Specification: Interactive Turbocharger Compressor Map Plotting Tool
Overview
A specialized, client-side browser application designed for automotive enthusiasts and engineers to plot and visualize turbocharger performance data. The app provides a canvas for mapping engine operating points (Pressure Ratio vs. Mass Airflow) onto a background representing a turbo compressor map.
Core Features
- Live Map Generation: Dynamically renders compressor map curves, efficiency islands, and surge/choke lines using Chart.js.
- Operating Point Plotting: Allows users to input engine data (RPM, pressure, temperature) and maps those points onto the chart overlay.
- Data Import/Export: Import CSV or JSON coordinate data; export charts as high-quality PNG/SVG images.
- Safety Zones: Visual indicators for surge and choke regions to prevent turbo damage.
- Zero-Storage Architecture: 100% in-memory data processing for maximum privacy and compliance with restricted iframe environments.
UI/UX Design
- Layout:
- Header: Clean, professional navigation with utility labels.
- Sidebar (Left, 30%): Collapsible input section for 'Map Coordinates' and 'Engine Points'. Uses clear, labeled inputs for X/Y coordinates.
- Main Viewport (Right, 70%): Large, responsive canvas for the chart. High contrast for data points.
- Overlay Modals: Custom-built HTML modals for error reporting (e.g., 'Invalid Coordinates') instead of standard JS alerts.
- Color Palette (Light Mode Only):
- Primary Background: #F8FAFC
- Card Background: #FFFFFF
- Primary Accent: #2563EB (Electric Blue for active chart lines)
- Secondary Accent: #DC2626 (Danger Red for surge/choke regions)
- Typography: Inter, sans-serif; Dark slate for text (#1E293B).
Technical Requirements
- Single File: All logic, styling, and vendor scripts (via CDN) contained within one index.html.
- No Persistence: STRICTLY prohibited from using localStorage, sessionStorage, or IndexedDB. All state held in a central JavaScript object.
- Security: Must function inside a null-origin sandboxed iframe. No popups or external navigation.
- Responsive: Fluid resizing for the chart container. On mobile, the sidebar stacks above the main chart view.
- Libraries:
- Chart.js (v4.x) for high-performance plotting.
- Chartjs-plugin-annotation for drawing efficiency islands.
- Tailwind CSS (via CDN) for responsive utility-first styling.
Animations
- Smooth transitions on chart load using Chart.js built-in animations.
- CSS hover states on sidebar input fields (subtle box-shadow increase).
- Soft fade-in for results section using CSS keyframes.

Frequently Asked Questions
Everything you need to know about using this application.
How do I read a turbocharger compressor map?
A compressor map plots the relationship between airflow (usually in lb/min or kg/s) on the x-axis and the pressure ratio on the y-axis. The map contains 'islands' that represent the compressor's efficiency at various operating conditions. To use this tool, plot your calculated engine operating points on the chart. If your engine's speed and load line pass through the center of the efficiency islands, your turbocharger is well-matched. If the points fall outside the surge or choke lines, you may risk turbo damage or performance loss.
What data do I need to use this compressor map tool?
To get accurate results, you need to input the turbocharger's manufacturer-provided compressor map data points, which include surge lines, choke lines, and specific efficiency island boundaries. You also need your engine's airflow calculations based on your target horsepower and engine displacement. Once you have these coordinates, simply enter them into the data sidebar to generate the map. The tool will calculate the visual overlay for your engine's specific operating trajectory, allowing you to see exactly where your turbo operates under different boost levels.
Can I save my compressor maps for later use?
Due to our privacy-first, serverless architecture, this application does not store any data locally or in databases. Every calculation is performed in-memory, ensuring that your sensitive engine configurations are never saved or sent to a third-party server. For your convenience, we have included an export feature that allows you to download your generated plots as high-resolution images. You should save your data externally in a text file or spreadsheet to re-upload it whenever you need to revisit your project.
Is this tool suitable for professional automotive engineering?
This tool serves as an excellent visualization aid for automotive enthusiasts, students, and mechanics looking to understand forced induction systems. It utilizes robust Chart.js plotting to ensure accurate rendering of the mathematical relationships between pressure and flow. While highly accurate for visualization, it is intended as a supplemental utility. Professional engine calibration and turbo selection should always be verified against official manufacturer technical documentation and real-world dyno testing data to ensure engine safety.
