Refit the 2.6 ecu and get the dealer to tell it that it is a 3.2.

If you fit the 3.2 transponder, you will also need the matching key chip (plus programming additional chips for any other keys).

Ultimately it will be easier to tell the 2.6 ecu that it is now a 3.2 than trying to explain why the Ecu Vin (if you even know the Vin of the 3.2 donor) doesn't match the car...

Thank you but everything is done  ;)

To swap an engine ECU in a post 96 Omega, you need to swap the main ECU, Immobiliser ECU (around ignition switch) and key transponders.  Else you need a tech2 and the original carpasses to reprogram it all.

I had everything, simply my opel service could change it to manual although the speed control does not work despite being active, they could not tell me why

Failed clutch or brake light switch (brake light is two channel) or they inadvertently turned it off.

But I still don't understand why you fitted the 3.2 ecu in the first place.

When you first asked the question ages ago, I said, " remove the sensors and wiring loom from the 3.2. Remove the same from the 2.6 and fit them to the 3.2. Fit the 3.2 with the 2.6 sensors and harness into the car and plug it back in."

I don't recall the point that it was already a manual, as most 3.2 manual conversions done in the UK were already 3.2 so 'just' the gearbox change...

You had the easiest route possible, and have overcomplicated it to the point that a VAG engineer would be impressed...  :-\

If it fundamentally worked with the 2.6 ecu, I would go back to that step. Make sure that it runs and that everything works as intended, then get the 2.6 ecu told that it is now a 3.2 manual with cruise control.  ;)

My car was already manual, but the 3.2 ECUs are automatic, just change the ECU settings to my manual car, I don't see the complexity

I will ask my opel service if they can do it, I did not know that it could and I had already bought everything from 3.2. Seeing the problems that they put me for manual conversion, I simply went to what would be easier

Doctor Gollum

Easier would have been to run it on the original ecu. That was the advice almost two years ago.

2.6 ecu, box ticked as a 3.2.Confirm that the gearbox is still a manual and that cruise control is active.

Tech 2 should see the clutch switch and brake switch as part of a diagnostic function test, but if the car had cruise control before the original 3.0 conversion, then it should still work unless something is missing or broken.  ;)

It does not go the same with the ECU 2.6, it runs a lot more now in low and medium at least that is my daily use
The one to check the box was never said, and I find it strange that it can be done by not sharing reference ECU 2.6 with 3.2. On the other hand, for manual or automatic they are the same. Have you performed that operation? You never mentioned it to me, you always said it was an unnecessary expense and that it was the same with the ECU 2.6.

Doctor Gollum

My 3.2 manual ran perfectly fine with a 2.6 ecu and the inlet, injectors and throttle body are identical. Similarly, that ecu was used for diagnostic purposes in at least two other cars without issue.

Your initial query almost four years ago was to replace the 2.6 with a 3.0. No mention was made re gearbox, but the suggestion was made to swap the 2.6 sensors and harness onto it, but that fitting a 3.2 made more sense as everything was guaranteed to fit.

Two years ago, you were adamant that you wanted to fit a 3.2 ecu. Again you were told that it wasn't necessary. Yet here we are...

TB has explained how the 2.6 ecu can be 'corrected'. It already contains the map required. Yet you tried to have the 3.2 ecu programmed.

The issues stem from the drip feeding of information. For example:
Are you still running lpg?

How is it running the 3.2 ecu if you haven't changed the transponder?

It's possible that the details are getting lost in translation :-\

and the ECU will be set up for 2.6  ???
Not if you tell it that it is running a 3.2 ;)

BUT ...
has the emulator been told and adjusted is what i'm saying  ;)

That should happen when you check the box for the engine type.   :-\
