  Tutorial: How to unlock Continental PCR 2.1 from Audi using   Scanmatik2 Pro , pcmflash and   godiag GPT Boot ECU Adapter . You should first open it because need the password. Here is the wiring diagram (for pcmflash only). You must solder two resistors. Have SM2 connected. Here is the pinout and you can see how to make the connections. But actually you need only Power, Ground , CAN High and  CAN Low,  you don’t need to connect GPT 0 and GPT1 to read this. Solder two resistors, each one is 1kohm. Connect power supply with  godiag ECU adapter . It is really useful because you don’t want to solder the resistor. You can connect straight here because you have all these types of resistors and when you don’t push the button (switch button) it will take automatically the resistance and when you push the button it will jump to 100 ohms. This adapter is quite good for few issues. The connection is done. Now we open the pcmflash software 1.20. Select protocol 57. W...
