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
As Jack the Ripper would say, let's go by parts
We start from a 2.6 manual to which I mount the 3.0 with everything you need from 2.6 to work. I have been like this for about 2 years until it had a head gasket failure.
As I had constant adjustment problems with LPG I decided to leave the option of going with a 2.6 ECU and 3.0 engine to go to a full 3.2 as it would have left the factory to rule out problems.
And so I am now, the car is as if it had left the factory, so for any problem the possibility that the electronics is not what it should carry is ruled out
And yes, the ECU 2.6 makes the engine work, but it does not go as it should, now it runs faster than before. And it is logical, any modification requires remap and the omega is no exception
When I say that the ECU 3.2 is working with everything, it is understood that it has its immo and transponder, I thought it was taken for granted
