What it solves

It provides a professional, open-source tool for automotive engineers to edit and calibrate Engine Control Unit (ECU) hex files. It simplifies the process of interpreting raw binary data from various ECU manufacturers and allows for precise tuning of vehicle performance parameters.

How it works

The software acts as a hex editor specifically designed for automotive ROMs. It uses a parser to handle ASAP2 (A2L) files and supports importing OLS projects and KP map packs to identify data maps within the binary. It features a map editor with 2D and 3D visualizations to help users see and modify calibration data. Additionally, it integrates an AI assistant (via API keys or local models) to help users identify and explain complex calibration maps using natural language.

Who it’s for

Automotive engineers and ECU tuners who need to modify engine calibration data across a wide range of ECU families from manufacturers like Bosch, Continental, Delphi, Denso, and others.

Highlights

• AI-Powered Calibration: Integration with models like GPT-4o, Claude, and local LLMs (via Ollama/LM Studio) for map identification and explanation.
• Advanced Visualization: Interactive 2D and 3D map views with heat gradients and real-time waveform previews.
• Broad Compatibility: Support for a vast array of ECU families (Bosch, Continental, Delphi, etc.) and file formats (HEX, BIN, S19, A2L).
• Cross-Platform: Native desktop application available for Windows, macOS, and Linux built with Qt 6.
