Note: the list above was copied from the program’s own “Info / Supported” dialog in the screenshots; exact coverage depends on the BIN you load.
Basic usage
- Make a full backup of your original BIN before any edits.
- Open ECU BIN → review identification → change required parameters/flags → save a new file.
- Write the edited file back to ECU using your preferred flasher/programmer.
- Use at your own risk; for service and research purposes by qualified personnel only.
Package contents
