Calibration Platform Compatibility


The authorised access workflow enables use with leading calibration and flashing platforms, including:

  • MHD / MHD+
  • bootmod3
  • MG Flasher
  • CMD
  • Autotuner
  • Alientech
  • Flex (Magic Motorsport)

The ECU remains in its original factory configuration, allowing seamless integration with CAN-based auxiliary systems such as port injection control and additional fuel management modules.

Authorised Calibration Access Methodology

  • Authorisation-based, software-controlled workflow
  • No physical ECU modification
  • No enclosure opening
  • No PCB alteration or additional wiring
  • OEM hardware and casing integrity preserved

The process is conducted entirely within a controlled authorisation session.

The Hardware Security Module remains active, the secure boot chain is preserved, and the Boot ROM is unmodified.

All operations are performed through a server-validated procedure that enables legitimate calibration writing while maintaining full factory security architecture and traceability.

The Engineer

Sam is the lead engineer behind the development of our ECU unlock process, responsible for designing and validating the non-invasive software method deployed across all Protocol One locations.

With a background in embedded systems, Bosch MG1/MD1 PowerPC (MPC5777) architecture, AUTOSAR-based control units, and OEM diagnostic/communication protocols, he engineered a solution that preserves full factory hardware integrity while enabling consistent and repeatable unlocks without ECU opening, soldering, or cloning.

His work centres on secure boot chain interaction, RSA signature handling, checksum verification, and encrypted flash data management, alongside strict voltage-stabilised programming environments and controlled session procedures.

By operating at the calibration and bootloader interface rather than modifying executable application code, the process maintains OEM software structure while allowing reliable post-unlock flashing across supported platforms.

This methodology ensures data integrity, platform compatibility, and a uniform engineering standard for both retail and trade operations throughout the national Protocol One network.
