Title: Help with tech2 auto to manual conversion
Post by: olm on 15 December 2021, 19:59:00
Hello. I wanted to ask a question about converting the ECU 3.2 auto to manual. I have spoken with my opel workshop to do it but they have never done it and they do not know how to do it. They say they will enter my chassis number but it will appear that it is a 2.6, will I need a number of 3.2? Could tell me in which areas of tech2 would you have to go to configure it and explain it? They tell me to try but they don't guarantee anything
Thanks

In what menu? It is easy? Doesn't matter if you insert my chassis number? I have to chew it on them because they have no idea and they will charge me the same if they don't ... :-\

You can change the transmission type as part of activating  cruise control. This tells the ecu the type of transmission fitted. It should then sort itself out from there.

You will need to have the clutch switch fitted but the wiring should be present.

Ops, If my car is manual, I won't have the clutch wiring, right?  :-X
Now that I think about it, you mean the clutch sensor for cruise control, that I do!
The chassis number then, does not influence? Will you treat it normal despite having the 3.2 ECU?

It should be factory fitted as part of the dash loom regardless of gearbox type.

If not, easy to wire in. Positive feed and ground.

Can't off hand recall which way around... Either from the engine ecu to ground or it grounds through the engine ecu.

Be some detail in the retrofit cruise guide.

It brought the pre-installation of the cruise control, connect the lever and the pedal sensor but do not activate it because it does not have tech2, but in theory it is ready to work. Would that be enough?

They're two steps of the same process ;)

The only caveat is that the clutch switch must be fitted and there must be no autobox wiring connected to the engine ecu.

The manual engine harness includes the reverse light switch so you'll need to swap that from the autobox loom. (This isn't critical for getting the gearbox updated, but is potentially a legal requirement.)

Then if they go to cruise control in the 3.2 engine ecu using Tech 2 and make sure that the transmission is confirmed as manual, that should suffice  ;)

TheBoy/Kevin Wood will be able to give more details about   navigating Tech 2, but the gear box choice is literally checking a box ;)

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?

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.

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 :-X
Title: Re: Help with tech2 auto to manual conversion
Post by: TheBoy on 17 December 2021, 10:25:07
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

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.

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.

OK, I over simplified. But the injector timings are based on engine load, one of the variables being air drawn in. The larger displacement will require more air and therefore more fuel to maintain the correct mixture.

However this is a moot point if the ecu can be told what it is connected to...

So about what I have can I convert it to 3.2 manual? Wouldn't it be necessary to put the 3.2 when going to the opel service?

Right, the ECU adds injection times based on lambda to make it work, but it does so based on a base map, if that base map is designed for 600cc minus the fuel trims go up. And they go up too high for my liking

On a petrol V6, or LPG converted V6 running on petrol, the LTFTs should remain at 0%.

There is a difference in the configs between the 2.6 and 3.2 (else they wouldn't give it as an option), which I would have to assume is mapping.

It would clearly make sense to have the ECU running the correct map for the injectors and engine CC, along with other configs.


I might have missed it, what was wrong with the original ECU?  They are absolutely bulletproof.  The only one I've seen that was destroyed was one of Gixers....   ...after he was playing with electricity around it, not his forte I'm sure he would admit.

Only reason the Tech2 needs to talk to TIS (any variant), is to authorise the Tech2 for that ECU serial number.  With TIS2000, that needs no VIN etc. Would TIS2Web need anything though?

Never really bothered with newer versions beyond May 2008's TIS2000, as wasn't needed on Omegas, so minimal experience of the online one.

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...

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.  ;)

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.

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?

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.   :-\

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

OK. To be clear:

1. The car is not currently fitted with lpg?

2. The car functions correctly, including cruise control, with either ecu?  (this assumes the chip and transponder match the ecu being used regardless of which ecu).

3. The 2.6 ecu does NOT require remapping. It already contains the programming, but needs to be told that it is now running a 3.2 so that it can use the correct parameters in order to use the correct map.

Yes, but until gasoline goes well I'm not using it

No, cruise control does not work

I already think it is too late for the 2.6 ECU remap, unless the problems could come from a faulty 3.2 ECU

Remapping the 2.6 ecu is NOT required.

It already contains the ability to run the 3.2 as a 3.2.

It simply needs telling that it must follow the correct map for the 3.2 with a manual gearbox. The map is already there in the programming.

Assume you live on a block, and there is a shop on the opposite side of the block. As long as you can remember, you always turned left from your door to walk to the shop. And when you left the shop you always turned left to return home.

Now imagine if someone told you that if you turned right, you would still arrive at the same place.

You are the 2.6 ecu, and someone needs to tell you that you can turn right, ie think that you are a 3.2.


BTW, I wager that the cruise control would work if you refitted the 2.6 ecu  :-X

I know what you mean but that information is late for me, you always said to use the ECU 2.6 without reassigning. However, it doesn't matter, I already have everything from 3.2 in the same way. Now to solve the fault 0430

 Well, it is already solved, you are not going to believe it. In the end it was ... the distribution! Bank 1 was one tooth behind. It seems that the tensioner was bad because when I put it on its marks by doing 2 laps it was bad again. Looking closely, when I moved the crankshaft I had some play until I moved the cams and I was already unbalanced. When I finally get everything to fit, when starting it sounded very bad and I stopped it immediately. Buy a new distribution kit and the first time everything is ok. It seems incredible to me that the car worked perfectly, smoothly and without problems and it was the ECU 3.2 that pointed out the problem because with the ECU 2.6 until the idle I had it right.  :o

So nothing, mystery solved and thank you all very much for helping me  :y :y

That's a relief  :y

And why you should always use a reputable locking kit ;)
