We are proud that Hexprog is the only tool can read/write CAS4 without de-soldering or cutting any part from the board. With Hexprog you are able to break the protection of immobilizers like CAS in BMW, EIZ/EIS in Mercedes Benz, BCM in Volkswagen and Porsche…etc. With Hexprog you can read all long ISN from any BMW Ecu including the latest Bosch MG1/MD1 Ecus starting from 2005 up to today's DME/DDE. We took the most important part from Autohex for ISN management and we adopt it in Hexprog. Hexprog Chip Tuning function by OBD BMW ISN reading: Microtronik has a huge experience in all types of car Ecus flashing and coding, we deployed this experience in Hexprog to produce one of the safest programming tools by OBD. It also includes important functions in some Ecus, like VIN Changing, Coding backup/restore and Fault codes read/erase. Hexprog starts supporting OBD functions in early 2021, It supports read/write the map area, (virtual read is supported too). You can check Hexprog Ecu List OBD Chip tuning: This method is useful when the Ecu is not responding. Boot mode: Opening the Ecu is mandatory to connect the boot wire on the Ecu board.Just plug some wires for power and signals and you are ready to go. Factory mode: with this option you don’t have to open the Ecu cover.You can read and write P-Flash, D-Flash, External Flash, and external EEPROM with the option of automatically checksum correction, you will have two methods in most of Ecus: The result was an amazing tool can serve the users perfectly. Hexprog tool was designed on this philosophy, we took care of every small detail when we built the hardware, and we used our vast experience to make a fast, reliable and user friendly software. Chip tuning, Ecu cloning and other programming tasks require a high-performance tool in both hardware and software.
