Been a while since I did it, so the steps might be vague, but hopefully good enough.

Go into diags, then into engine, then the engine type.

Then go to the option that is something like variant config.  Here you can adjust various configuration bits, including whether it has cruise, but also Transmission type.

Note - the Tech2 needs authorisation to do this on that specific car.  So its not just a case of having a Tech2.


You might also have to do the same in the ABS (can't remember is that has a gearbox config), as it sits on the same CAN bus.

My car is 2.6 and it will have a 3.2 ECU, will there be a problem when entering my chassis number?

[Doctor Gollum]

Why do you need to do that? It simply isn't relevant.

The Tech 2 reads that from the ecu.

As long as the immobiliser chip, transponder and ecu are from a single vehicle, they could be fitted to a chainsaw.

The opel service told me that it connects with the central over the internet by entering my chassis number.
The switchboard, immo and transponder are from the same car

[Doctor Gollum]

Do you happen to have the car pass for your car and the donor?

Then tell them to skip the Vin imput

It can? What idiots if you can and they don't say it. Another option would be to give them a chassis number of a 3.2?

You don't enter a chassis number.

At the same time you are doing the variant config, you can set the ECU to the correct engine.

Which implies that the original 2.6 ecu can be 'corrected'...

In which case the original advice to fit the 2.6 sensors and loom to the 3.2 lump and retain the 2.6 ecu/chip/transponder was correct all along

[TheBoy]

The procedure is simple, and is under:

Diagnostics > "Model Year" > Omega-B > F0-Engine > Y32XE > Confirm

From there is where I'm vague, as I don't have an Omega to confirm, and its been ages since I did it. As said, its somethign like Variant Config, probably under Programming, but could be under Additional Functions.


When on the right page, it will show a list of available options, which you just adjust as required, and then hit the Program soft button.



However, as said before, your Tech2 will need authorisation for this specific vehicle via TIS2000 or GlobalTIS.  Given your Engine ECU might have wrong VIN (which you can adjust if you so wish), *IF* the ABS needs adjusting (can't remember to be honest), that might need Tech2 reauthorising again.

ABS (If it has gearbox setting in its variant config) is similar process, but is under Chassis > ABS/TC instead of Engine > Y32XE


MID/GID/CID should technically be done, but not essential. That just needs the Variant Config code looking up on TIS2000/GlobalTIS. No authroisation needed for that.

But that was not told to me, they never talked about being able to configure the ECU, it was said to circulate with a 3.2 engine and an ECU 2.6, which seeing the fuel settings, is not a good option

[TheBoy]

Standard* 2.6 and 3.2 ECUs are identical hardware and software, with configuration options to adjust between different settings.



*The are some variants, that have different maps, for non standard cars, like a few (but not all) UK spec police cars.

[Doctor Gollum]

Fueling is done via the MAF.

Which is the same 2.6/3.2, as is the throttle body/intake/plenum/Fuel rail/injectors...

The only difference is the crank and cylinder displacement.
