Hi, I am looking for a 3.2 ECU and I wanted to know if with the reference 0 261 206 492 it is 100% omega or it can be from another car. I have seen one with that reference that claims to be a zafira, is that possible? If so, what else should I look at?

According to this, it is correct for the 3.2 Y32SE engine...

There are cheaper ones out there if you are buying one...!

Yes, I'm looking cheaper but they don't know what car it is
This is the reference

Here, it said that is from a Zafira

And here, too

Is this possible?

Just the ECU on it's own may prove problematic without the security code
which you need to change model, parameters, trim level etc
depends what you want to do with it 
paperweight

  I need the security code? I want to use for a 3.2 swap on my 2.6

do you have the security pass card for your 2.6 ?

I'm not sure but I would say yes. If I don't have it, could I ask Opel for it? And would my code work? I guess I would need the tech 2

The immobiliser is paired to the ECU.  An ECU alone will not allow the car to start, as the ECU isn't seen a valid Permission to Start code from the immobiliser ECU.

Ahh, no problem, I have someone to cancel the immobilizer if necessary, if that's why I don't care

the Y26se ECU you have fitted may possibly be configured to Y32SE with Tech 2 
I know the ECU hardware(box) is common to many models on vauxhall ECUs but requires virginising and setting to the model plus application ,saloon or estate, AC or not etc etc

If e can do tat, can't e reconfig the variant coding then?

A few years ago, the battery on my 3.2 auto 'spiked' the ECU and the car was dead. At the time, I could only get a replacement ECU off a manual 3.2,  no pass, key or immobiliser ring etc -  just the ECU. A former Vauxhall technician / auto electrician who (I was told by other VX techies) was 'pretty good' with VX electrics 'wiped' the ECU and then reconfigured it to my car. The only hiccup was that it still thought it was in a manual car, but once that was sorted for an auto, all has been well since. That is my 'layman's' description of what was done, by the way....
In essence, the right person should be able to reconfigure just a replacement ECU on its own to your car without the other immobilser bits meaning you can keep the original keys and locks etc.
