BitBox Trucks Delphi ETC3

A BitBox software module made for trucks that have Delphi ETC3 ECUs controlling the engine.

The module lets technicians or tuners read data from and write data to the ECU via the OBD2 diagnostic socket or on a bench.

It supports CAN‑bus communication with these ECUs.

Notes:

• Older or different revisions of the ETC3 ECU (REV 0 or REV H) may not be supported.

• Some units with more advanced protections might also not be compatible.

 What It Actually Does

With this module installed in your BitBox setup, you can:
✔ Read the calibration and software data stored in the Delphi ETC3 ECU.
✔ Write updated or tuned calibration data back to the ECU, with automatic checksum correction so the ECU accepts the changes.
✔ Do it either through OBD2 or on a bench, depending on your hardware and setup.
