Description
Bin comparator is a lightweight Windows desktop utility designed for automotive enthusiasts, calibrators, and ECU tuners to quickly identify, isolate, and inspect byte-level differences between stock and modified binary flash files (.bin).
Key Features
Binary Comparison Engine: Scans and cross-references two binary dump files (Stock vs. Tuned) byte-by-byte, automatically grouping contiguous modified bytes into isolated difference blocks.
Offset & Size Mapping: Displays every modified memory region in a clean list view, showing the exact hexadecimal start and end addresses (
0x000000 - 0x000000) along with the total block size in bytes.Dedicated Binary Filtering: File selection dialogs are strictly filtered to
.binextensions, preventing accidental loading of incompatible file formats.Persistent Session State: Automatically remembers the last accessed directory and loaded file paths in a local configuration file (
ecu_config.json), restoring them upon restart.Standalone Native GUI: Built on .NET Framework 4.0 (Windows Forms) and configured to launch directly as a pure Windows application without opening background console or DOS windows.
