Help with tech2 auto to manual conversion

[Doctor Gollum]

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...

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.

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?

It sounds like the dealer is using Tis 2 Web rather than standalone TIS.

This will indeed pull the VIN number up

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.

I'd assumed it was a back street garage for some reason, hence the warnings that it needs authorisation

Oh nothing, in fact I am running with the 2.6 ECU the 3.2 engine but as I say, the LTFTs are very high and that is why I wanted to mount the original ECU.

It is an official opel service. Hence my fears, they are not used to doing things that are out of the ordinary

Telling the ecu that the engine is a 3.2 should solve that.

If it's that easy I shoot myself hahaha

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.

Well, in the end they could do it without problem although the speed control does not work despite being active, but that will be seen. Thank you very much to all for the tips

Another question, how is the immobilizer module changed? Is it necessary to remove the cylinder from the key?

Yes. But we have established that you don't need to change anything except the programming.

I have mounted ECU 3.2 so I need the immo
