Hey I own a Jaguar XK8 2001 Coupé 4.0L (LHD)

I'm starting this thread to see whether anyone is aware of a service in the United States or possibly as an option the UK for reprogramming donor ecms so that I can plug and play for my car.

-Context
At the moment I lack the IDS proper materials to use it on my vehicle and much rather send my donor ECM that I know is working for programming to use in my vehicle. My ECM (original) has a short that I could not locate and was unable to find a circuit diagram of the ECM for the Jaguar XK8 and a Jaguar dealer is no help.

Reverse engineering is not an option as it's my only working coded ECM for the car. And yes it's confirmed (another thread) that the ECM is the issue, and after dismantling I tested circuits to find it is a short but unable to find where it affects the h02 circuit.

As the two modules have identical VCATS numbers there is nothing else to configure, other than immobiliser setup. I can't see how you can do that with the ECM out of the car, rather than in the car connected to the SLM as the two must have to swap some ID data.

Is there any reason you don't want to go the IDS route at the moment, other than it's a PITA?

 

The North American 1997 XK8 is the ONLY ECM that I think will swap with just a same VCATS.
No RFID or key transponder for that car in the U.S.
1998 was the first year here to have the RFID.

All other 4.0 Jaguar XKs need an IMMOBILIZATION SETUP.

The ECM needs to be connected to the car's CAN bus as dibbit states.

The AJ26 and AJ27 ECMs are different.

 

Specifically the PITA and the funds I don't have at the moment to continue getting what I need to complete the job
