ECUHELP KT200 ECU Programmer has been successfully utilized for unlocking, reading, writing, and verifying checksums for the VW Simos PCR2.1 ECU directly on bench. This comprehensive guide provides detailed visuals and instructions to ensure flawless execution of these tasks.
The first image shows how does KT200 is connected to the PCR2.1 and the ECU.
The second image shows the result of using KT200 to write PCR2.1 100% ok.

Connect the bench box v.2 to the tool and connect the multifunction cable as follows:
To read and write use the following driver:
→ BENCH MODE
→ VW / AUDI / SEAT / SKODA
→ TC1796 – VAG
→ SIMOS PCR2.1
ATTENTION:
In addition to reading/writing the full backup, you can also use this driver to unlock the serial write for the OBD driver “R/W MAPS”:
By loading the EEPROM file, if the software sees that the
Eeprom is locked, and the following message will be displayed:
Set unlock EEPROM for
serial maps programming?
Choosing OK will apply the unlock on the EEPROM and you can also write the ECU in OBD using the serial driver R/W MAPS.
We also remind you that you can also read and write PCR2.1 via OBD using the driver:
SIMOS PCR 2.1 ONLOCK BY OBD *CAN
This driver reads the file with virtual read and unlocks the control unit directly while writing by applying a patch on the micro file during writing.
By the way, the KT200 has been upgraded to KT200 II and it’s working great! You can update yours now by just paying for the PCB board here:
