Exchanging an engine control unit/ transmission control unit in VAG vehicles using a distribution box and an Abrites Emulator (IMMO III/IV EMU)
This procedure is used when you need to replace any immo module with an Emulator. The goal is for the Emulator to emulate an Engine Control Unit or Transmission Control Unit in the IMMO system. Often times the CS and PIN of the ECU or TCU cannot be read(without opening the control unit) so you can use an emulator instead.
In the cases when you need to replace ECUs/ TCUs in VAG cars you can emulate the immo section so as to allow the module to work without the need of a complex adaptation. The function applies to the transmissions of Audi A6 2003-2010, Audi Q7 2005-2015, Audi A8 2003-2010, and for all Immo III/IV engine control units (EDC16/EDC17/ME7/MED9/MED17/Simos benzin/Simos PPD/Simos PCR/Magneti Marelli/
Delphi)
The function allows you to build immo-related parts in other vehicle, even when the brand or power different.
- The first step is to ensure the PIN and CS are read from the ECU (example using EDC17 in diagnostic mode):
(screenshot 1, 1-1 and 1-3)
You could try reading the PIN and CS from Immo parts adaptation > Engine Control Unit as well.
- You then need to go to IMMO PARTS ADAPTATION and go to IMMO III/IV EMU.

2.a Input the data you read from the ECU
- (2-2)
2.b.Press OK and make sure that the Emulator is connected to the internal CAN-BUS of the vehicle(it is also possible to connect through the DS box during the procedure):
(2-3)
RED - CAN Hight
BLUE - CAN Low
YELLOW - B+
BLACK - GND
2.c Select the unit you need (in our case this will be the master ECU)

2.d The procedure starts. Make sure you have internet connection and some patience.

2.e It is a matter of waiting for the calculation to complete (N.B. make sure you have a power supply on the car).
