Welcome to the bFlash Split & Rebuild Tool

This powerful utility is designed to give you precise control over your .BDC files by allowing you to easily separate and reconstruct them.

Split Files ✂️

Separate a full .BDC file into its constituent parts like Flash and Eeprom with just a few clicks. Depending on the ECU's architecture, the output will vary. Sometimes you will get a single `Flash` and `Eeprom` file, while other times you may get multiple parts such as `Flash0`, `Flash1`, `Flash2` and even `Eeprom0`, `Eeprom1`.

 

Rebuild Files 🧩

Reconstruct a full .BDC file by applying your modified elements onto an original, trusted base file.

 

Validate Files ✅

All files are validated against predefined profiles to prevent size mismatches and protect against potential errors.
