Hi,

There are two AUDM DC5R's and one ECU which came from one of them.
I need to find out which car the ECU belongs to. Here is what makes it tricky:

Car 1)
Compliance Plate: 01/2002

This car currently has no engine in the car and the original engine can not be put back in. I'm unable to plug in the ECU and test the immobiliser, as there will be no engine to try and start.

Car 2)
Compliance Plate: 09/2001

This car no longer has the original engine and currently has a K20Z1 with a KPRO.

Details on the ECU:
37820 - PRB - Q01
2069 - 200088

Base on the above information, is there any way to tell which of the cars the ECU originally belonged to?

Also, regarding the ECU serial number "2069 - 200088", is there any information behind these numbers, similar to the VIN? i.e car colour, year of manufacture

Thanks
