About Hextag:

HexTag Programmer is the an Ecu Tuning, Ecu Cloning and BDM tool released by Microtronik which can do a wide range of operations in multi car and truck brands. It can read the ECU’s D-flash and P-flash in fraction of seconds which is faster compared to any tool in the market.

With the help of HexTag you can clone/tune wide range of Ecus without opening the Ecu easily including Bosch MDG1 Ecus (See the list if Supported Ecus ), you can get some important info like ISN from BMW Ecus, below video demostrate how to read ISN from Bosch MDG1 DME/DDE.

You can also read ISN from all BMW MDG1 Ecus. Writing/modifying ISN in BMW MDG1 Ecus is available in Autohex II only.

When HexTag was designed, three major factors dominated the process:

  • Safety while using: All of us heard about Chinese tools corruping the EEPROM or D-Flash from CAS4 and CAS4+. We can assure you that HexTag is the safest tool in the world.
  • Ease of usage: HexTag is considered the most user friendly tool, you can with a few clicks complete the most complicated jobs, like repairing a module (FRM3), resetting mileage, retrieving or modifying ISN, Change VIN,etc.
  • Competitive price for users even if compared to low quality chinese tools.

Unlike most other tools HexTag takes care to the power supply for the connected control unit, the power monitoring system in HexTag monitors current and voltage supplied to the control unit which allows a very safe operation while reading/writing data. HexTag will shutdown power supply in a range of 10ms when it detectes a shortage or a high power consumption.
