A feature-complete web-based ECU tuning editor, comparable to WinOLS and TunerPro, just in your browser. View and modify calibration data in BIN files using JSON, A2L, XDF definitions (experimental OLS support).
- Load BIN File: Open your ECU binary file
- Load Definition: The Editor loads the correct definition, otherwise drop a .json .xdf .a2l
- Edit Values: Modify tables and values
- Compare (optional): Load an original BIN to see changes highlighted. You can also cross compare bins, parameters are matched by name.
- Save: Export the modified BIN file
- Auto-Detection: Automatically matches binary files to definitions via EPK verification
- Multi-Format Support: A2L, XDF (TunerPro), and JSON definition formats
- BIN File Editor: View and edit scalar values, curves (1D tables), and maps (2D tables)
- 3D Visualization: Interactive 3D surface graph for MAP parameters (mouse-draggable rotation/tilt) WebGL accelerated
- 2D Graphs: Line charts for CURVE parameters
- Heatmap Visualization: Color-coded table cells from green to red
- Compare Mode: Load an original BIN file to compare changes side-by-side
- Cross-Compare Mode: Load a different BIN file to compare changes over two definitions side-by-side
- Editable Axes: Modify X and Y axis breakpoints directly
- Batch Editing: Select multiple cells and apply add/multiply/set operations
- Change Tracking: Visual indicators for modified values with diff view
- Category Tree: Organize parameters by categories with fuzzy search
- Keyboard Navigation: Navigate parameters with arrow keys
