 Performing a full IMMO OFF on a Siemens/Continental SIM2K-140 ECU directly through the OBD port is generally not possible. To completely disable the immobilizer, you must modify the internal flash or EEPROM data. While some advanced programming tools can read and write parts of this ECU via OBD, the proper IMMO OFF process requires Bench Mode or Boot Mode connection. The standard workflow to achieve IMMO OFF for a SIM2K-140: 1. Read the ECU Data (Bench/Boot Mode) You cannot rely solely on the OBD port because full memory access is required to bypass the immobilizer security. Use a hardware programmer like the OBDSTAR X300 Classic G3 / DC706 , Xhorse Multi-Prog , PCMTuner, or Foxflash . Connect directly to the ECU pins on a workbench using the programmer’s specific wiring diagram. Read and save both the Internal Flash and EEPROM data to your computer. 2. Modify the Files (IMMO OFF Software) Hardware tools read the files, but you need specialized software to locate ...

  Magic Motorsport Flex programmer released an important update yesterday: supports Bosch MDG1 ECU boot mode unlock without shipping (No RFT). Here comes the latest Flex user’s test report on BMW Bosch MG1CS201 encryoted ECU unlocking: It takes so long time. But finaly did it. Use standard Magic Motorsport power supply. Boot mode unlocking ok. After unlocking it become standard bench protol as everyone have already. After this unlocking and if they flash back on stock will Ecu be locked again? Mope. It will stay unlocked. The methods are different. This is security bypass by hardware glitch, then unlock with patch. Autotuner doing this with software glitch.

 Read and write Ford Kuga DCM6.1 ECU with Foxflash programmer by OBD successfully. Ford Kuga 2016, 2.0, 110kw, ECU: DCM6.1 Mode: OBD HW: DS71–12B684-XB Read by foxflash. Checksum correction with foxflash. Write by foxflash. A short story. A quick internet search for the ecu identification numbers gave me a result that the ecu was DCM3.5 (140hp) Wrong… It wasn’t!!! Foxflash did the ID even I selected DCM3.5 , I received the error SK2, Error SilentKey when reading. After I selected the correct ecu DCM6.1 (150hp) everything was fine.

  Problem: Tried to clone VW Golf 8 DQ400E gearbox TCU with Magic Motorsport Flex programmer but won’t connect. All pinned up correctly and on power supply. Won’t connect at all. Can hear it when pinned up. Any advice? Solution: Some users reported that VW Golf 7 works fine but Golf 8 won’t connect. Use a multimeter to measure your Flex pins, it’s a common issue for them to have no contact inside. Check wire and pins. Try to disconnect and connect back power supply to gearbox during connection establishing. If still not working, send log to MMS support or use other device. Launch X-prog3 read it fine. Read it with Launch + Xprog/ Launch X431 ECU programmer and it reads fine.

  Problem: It’s a Ford Transit 2018 with sid209 TC1797 ecu. Hardware number gk4a 12a650 ua. I’ve tried bitbox and Flex programmer . But hardware not compatible (obviously see hw not listed). Any solution? Solution: Sid209 GK4A version you need to boot unlock. Can’t write via obd straight away. Boot for readout, never had any luck with VR’s on GK4A. Same as Autotuner . Do it in boot mode or use other devices. Some had good success with Trasdata & PCM Flash.
