There are differences in wiring on some ecus. Car will not start. You will have to adapt immo/change login or immo off the new ecu.
You then will have to kill EGT Sensor, N249 and VVT because your APY does not have this. MAF can be different too.

Wiring is not problem for me.
In ECU beside IMMO off... I need in ESKONF kill rear O2,N249,and VVT...  (ignition maps)KFZW and KFZW2 make indentical. So is that all? Where to kill EGT?

i have managed to get it done, car is working fine. I removed few unnecessary wires, and pin 121 is now getting supply from ignition(15). That is solution for this DTC
Code:
17925/P1517/005399: Power Supply Relay for ECU (J271 or J363): Electrical Malfunction

I coded out VVT via ESKONF(but there is no need to do it beacuse car can ride normal,even when that DTC is there) and put wideband O2 , and basically that is all
If anybody have question fell free to ask  Wink

Did you remove pin 62 that operates the fans on narrowband as it's the egt signal on wide band?  I only know this from doing conversion myself on my old A3 1.8t quattro after converting to k04 and wideband. Now I'm wideband s3 (gave up on a3's body work. Picked up this 2001 s3 for 500 quid fully working minus a few issues and swapped hardware over) I done the full lot apart from adding egt. I added vvt + wideband 02 and maf. It was really easy to do tbh. Coding out shit off the ecu was the hardest part which again is still fairly easy.

If.you code out the plugs them selves and eskonf and do timing changes to disable vvt you should have no engine light on at all.

Yes i removed pin 62, and few more (i must see in my shematic whitch ones)
Still i am searching how to remove rear O2 and code out VVT.
At the end conversation is not that hard, the MAFs are same, acceletor pedal, coils.

Just use the search function in this forum it's all here bro. Coding out egt and rear O2 while setting readiness for emissions it's fairly simple to do.

This is my first time with ME7 ecu, so I take time, go easy and thoroughly. I don't like to do something that I don't undestand.
And at the end, the car is no longer with me. But I am doing AEB to wideband, than i will get the chance to code out all that stuff

Thank you for your regards  Cheesy without this forum nothing of this would't be possible.

I instaled AWT instalation and ECU (DBW) on AEB (DBC)
The car is starting and work's fine. But immediately I get DTC camshaft position sensor G40
P0341

I instaled 4 gap rotor, and try few camshaft position sensors. But DTC come back. I will check wires and with osciloscope signal. But before that,did I forget something?
Coils,throtle body,O2,MAF,MAP all is instaled from AWP engine.
I didn't connect SAI,EVAP,N80 but I think that doesnt't have any influence on DTC I get with camshaft
