Main Functions
HEXPROG II supports a wide range of engine and automatic-transmission controllers from manufacturers including Bosch, Continental, Delphi, Marelli, Denso, Temic, TRW and Valeo. Coverage includes applications across cars, trucks, motorcycles, tractors and marine vehicles.
Depending on the ECU/TCU and protocol, its core capabilities include:
– ECU & TCU Read / Write
– OBD2 Programming
– Bench Mode
– Boot Mode
– JTAG access
– ECU/TCU cloning and replacement workflows
– P-Flash & D-Flash read/write
– External Flash read/write
– External EEPROM read/write
– Automatic checksum calculation on supported Flash operations
– Virtual reading on supported OBD applications
– ECU coding backup and restore
– VIN-related service functions on supported applications
– Diagnostic fault-code reading and clearing
– ECU repair and recovery workflows
– BMW DME/DDE ISN reading for authorized repair/key-service applications.
OBD2 Programming
HEXPROG II can communicate with supported control units through the vehicle’s OBD2 diagnostic connector, reducing the need to remove an ECU for compatible operations. The source lists virtual reading, writing, coding backup/restore and diagnostic functions among its OBD capabilities.
Bench & Boot Mode
For ECUs requiring direct access, HEXPROG II supports Bench and Boot programming. These modes provide access to memory areas such as P-Flash, D-Flash, external Flash and EEPROM, depending on the ECU architecture.
This makes the platform useful for legitimate ECU/TCU replacement, cloning, recovery and electronic repair when OBD access is unavailable or insufficient.
BMW ISN Support
A notable HEXPROG II capability is reading long BMW ISN data from supported DME/DDE control units. The product description specifically mentions support for newer Bosch MD1 and MG1 ECUs found in BMW F/G-series applications.
This function is intended for authorized ECU replacement, synchronization and related professional vehicle-repair procedures.
Wide ECU & Vehicle Coverage
HEXPROG II is designed as a multi-brand platform rather than a single-manufacturer programmer. Supported controller manufacturers include Bosch, Continental, Delphi, Marelli, Denso, Temic, TRW and Valeo, while vehicle applications extend across passenger cars, commercial vehicles, motorcycles, agricultural machinery and marine systems.
Recent published updates also demonstrate ongoing motorcycle ECU coverage, including additional BMW, KTM, Bajaj, Can-Am and Indian applications.
Full vs. Basic Version
HEXPROG II Full includes licensing for the supported Bench and OBD 12/24V protocols and is supplied with a 1-year update license according to the current listing. After the update period ends, the device continues operating with its existing licensed functions; a new update subscription can be purchased separately.
HEXPROG II Basic uses a flexible activation model. The source states that an activation remains active for 48 hours, after which the device can be activated again when required through the user’s account; the number of activations is described as unlimited, with time-based licenses available separately.
Package Contents
The listed package includes the HEXPROG II programmer, OBD2 cable, Bench cables, JTAG/BDM cables, power supply and USB cable.
Ideal For
HEXPROG II is particularly suitable for professional ECU/TCU programming workshops, automotive electronics repair centers, diagnostic technicians, chip-tuning professionals and specialists performing authorized ECU/TCU replacement, cloning, backup and recovery work.
