BitBox Honda Moto Shindengen

It’s a software/firmware module (product number MK23076) for use with the BitBox toolset.

Works with ECU versions based on Renesas V850/RH850 microcontrollers with internal flash memory (about 256–384 KB).This module lets technicians perform advanced ECU operations, including:
✔ Identifying the software loaded in the ECU
✔ Virtual reading of ECU software (when supported by online server files)
✔ Writing software back to the ECU over K‑Line communication
✔ Checking and calculating checksums
✔ ECU recovery if needed
