I know that there are a lot of topics about this, but i didnt find any info for Ibiza(6K2).
Ibiza ecu is 6K0 906 032 AA
I bouht the ecu of VW Bora 2003 year, ecu 06A 906 032 HJ.
I disconected both o2 sensors(narrowband) just to try and start the car.
I did immo off. Car starts,  radioator fans go full speed, and no throttle response, shuts down after 2 seconds.
How can i check the wiring? Maybe i did immo off wrong?

Errors from ecu(06A)

17931- Crash Signal from Airbag Controller
18058- Powertrain DataBus
17987- Throttle actuator
17069- ECM Power Relay Control Circuite.

Power needs to be ran to small plug on the ecu for throttle power. Ecm relsy grounds a circuit that powers the small plug on the ecu. Fan control wiring pin needs to be changed. Powertrain data missing is from no asr esp
Ive done the swap a few times info in on google

on the AUM/AUQ ecu pin 121 is the main power feed to the ecu, if you are using an aum/auq then you will need to run a good ignition live feed to this pin from somewhere. pin 21 is the earth trigger for the ecu relay, as i say you dont need to use this but if you ru8n it to your ecu relay then that will stop the fault code above.

the ecu relay wiring for the aum/auq is easy to add, run the live pin 30 & ign live pin 86 to one of the fused contacts on the battery junction box (15a ideally) earth pin 85 to ecu pin 21 and the output pin 87 to the ecu pin 121

I found this and did like that. Only problem now is the fan that comes on and off....
