BitBox Module PSA Petrol CAN

BitBox Module PSA Petrol CAN is a software activation module (license) used with the BitBox ECU reflashing/flashing system — a professional automotive tuning and diagnostic tool. It lets you read and write engine control unit (ECU) data on petrol‑engine vehicles from the PSA Group (Peugeot and Citroën) that communicate via the CAN bus (Controller Area Network).

Key Functions

✔️ Read & Write ECU Calibration Data via OBD2 — Allows reading and writing the calibration (tuning) area of supported ECUs through the vehicle’s diagnostic (OBD2) port.
✔️ Checksum Correction — Automatically recalculates correct checksums when writing data back to the ECU, preventing corruption or errors.
✔️ Supports Specific ECU Types — Designed for Valeo and Bosch‑based ECUs used in PSA petrol vehicles.
