Passat CC EDC17c46 adaptation

[amigokola]

Hi Guys...
Is it possible to adapt used ECU - EDC17c46 with other Power Class ??
I tried with SMOK UHDS. I read used ECU by CAN connection and got all data. Ori data got from CCM (also from ori ECU and it match perfectly).
Used EDC17 UDS OBD option from SMOK menu and it wrote all data besides MAC1 MAC2. Then tried all systems IMMO3 and Passat CCM to login and change data but I lost ignition.
I have backup of CCM eep.
I know that it is possible to clone ECU but this one has other HW so it cant be done I suppose ??
Manual decode and change data in ECU is also the way but I would like to know what I do wrong with OBD option ??
Maybe other Power Class is something not to be overcome ??
Rgs.

Anybody ??

if the PC disagrees, it will not adapt successfully. you have to change the PC in Immo, or do ImmoOff in ECU. Why doesn't the PC agree? do you have different ECUs?

ECU has the same number from VW and Bosch but HW is different.
I've changed PC in CCM but still no go with adaptation.
Dont know if ELV also consider PC from CCM ??

Change power class in ECU MEDC17 family is possible I make this from long time.

Ok so if PC match there should be no problem to adapt EDC17c46 by OBD in Passat 3C ??

I not know about OBD , many adaptations in immo area I made by hands on files , then no adaptations by OBD are needed.
At first what generation immo have Your CAR , second what is a task ? and of course where is descriptions , files etc.

I know that on dumps it is possible. I ask if someone did it fully by OBD.

OBD can be done if you have same PC, if not same , then need to find out PC in ECU and change it it is CCM manually . PC can not be chnage OBD in most modules.
Anyway PC will not make car has no ignition. I have done many Passats with VVDI2 and all went good OBD with same PC.
I think what you doing wrong , you trying to program CCM instead ECU.
