Will OBDSTAR DC706 Clone VW Continental Simos PCR2.1 ECU? This is a frequently asked question.
FC200, Launch X-prog3, Xhorse Multi Prog and many other ECU programmers can ONLY read and write PCR2.1 ECU on bench, they cannot clone this ECU.
OBDSTAR released an ECM update in August 2025.
* Add VOLKSWAGEN/AUDI/SEAT/SKODA CONTINENTAL/SIEMENS/ VDO PCR2.1 TC1796 EXT eeprom Data Convert (CLONE) function (BENCH).

You can’t just copy data on Simos pcr2.1. You can’t clone both computers because of otp zones. Sector OTP impossible to write.
Needs Immo data transfer. OBDSTAR now supports data transfer function.
You can also provide your eeprom and flash files of the original and donor to a professional tuner, they will recalculate your immo data. Find someone who can “merge” both files to get your ecu running.
Put virgin and adapt or do immo off.
Fit it to the vehicle a program used ecu with Odis online (sync new ECU into car). They make it easy really.
