BitBox China Delphi Petrol

• It’s a BitBox software activation/module from BitSoftware designed for reading and writing internal flash memory of Delphi engine control units (ECUs) installed in China‑made petrol vehicles.

• This module enables technicians or tuners to access, read, modify and write the firmware/calibration data stored inside those ECUs.

Key Functionality

• Read/Write Flash Memory – Read the full flash contents and write back modified data such as tuning parameters or firmware updates.

• Checksum Correction – For many supported ECUs, after editing the calibration data it can automatically correct the checksum so the ECU will accept the modified binary.

• Supports Various Delphi ECUs – The module lists support for several Delphi ECU types, such as MT20U, MT20U2, MT22.1, MT80, MT92/MT92.1, and others used on China petrol engines.
