Title: Ecu swapping...
Post by: Doctor Gollum on 10 March 2020, 09:33:01
On the Omega, if the ecu or immobiliser fails, you can pretty reliably swap everything with another one of a similar age/engine management... ie 2.5/3.0, 3.2/2.6 and have the car work fine.

Would this apply for other brands?

Electronic ignition on the Trolley replacement has failed, turns out that it has previously been replaced with one from a car with a completely different engine (which explains an interesting mod, namely an aftermarket start button :-X) .

I cannot get the relevant modules to exactly match the age/engine, but can get them to match the age and number of cylinders. Will these work?

The mods preclude it from going to a main dealer, as they would demand a new dash loom, which leaves the second hand route for the time being... Getting the remotes reprogrammed is a relatively easy option compared the potential cost of a dealer stripping the dash out.

It depends a lot on the architecture, I would expect the engine ECU to be at least coded to the BCM and possibly any specific immobiliser or key system.

On newer cars its even more tricky, with Telematics and other gubbins

Shopping list contains engine ecu, pair of keys, eis and shift assembly...

It's a pre facelift w220 petrol fwiw.
