Why This Update Matters
This AT Protocol expands AutoTuner ECU Tool coverage for Continental 5WY8 ECUs, providing direct OBD Normal Read (NR) access for supported Ford Group vehicles. With MPC5554 support, calibration read/write, automatic checksum correction, and read/write times of 3 minutes and 3 minutes 15 seconds, workshops can complete supported ECU programming tasks entirely through the diagnostic port without removing the ECU.
