I have two 06A906032DL ME7.5 ECUs. (2001 VW 1.8T AWW wolfsburg jetta)
1) My original daily driver ECU with APR KO4 tune (I have the dealer immo tag for this ecu)
2) My spare same PN ECU I got from the junk yard (I do not have the immo tag- but I was able to download EEPROM bin (attached)

Can someone please point me to the process/memory addresses in the bin file that I need to:
1) Locate/Transform existing IMMO pin and Update the IMMO pin on my spare ECU to match my current ECU so they can be hot swapped
2) Turn immo on/off
3) Confirm the immobilizer type 2/3
4) How are the checksums calculated for the Eeprom bins and what addresss are they stored at.

I tried to download turboat's EepromTool but got virus warnings.

I have VCDS and KKL cable so I am thinking in the worst case if I can figure out the pin on the junkyard ecu I can use it to login and update it to match my original ecu.

Thanks for the help. My goal is to understand how to do this manually, create some flowchart to help others through the process, and lastly create/port existing tools to a single java/d2xx based Eeprom tool tool that can run on windows/linux/android.

Please point me to the sticky that you are referring to. All the ones that come up in my search refers to immo 3 ecu or scenario where ecu is being replaced(not cloned so it can be swapped back and forth during development).  I know somebody must have run into this before so I hope they can provide me a bit more guidance.   

Visual ME7 logger do this yob with ME7check. You can use it too for testing
