Lambda Bypass Controller

[Usually007]

Okay everyone. Your starter for 10.

Has anyone had any experience of Lambda bypass/override controllers and any idea where I get one!

Do you mean a Lambda simulator?

[Usually007]

Possibly.

My mechanic has told me that he cannot get my Unichip programmed to fuel properly because the Lambda sensors cause the ECU to shut off!

Do a search on the web for o2 simulator. You should be able to find some.

A better solution would be to get it working correctly still using an O2 sensor. Maybe you need to take it somewhere else?

Cheers.

I might try a differnet rolling road.

You could try TDI - http://www.tdi-plc.com

They are experienced with the IS200, supercharger and Unichip.

What are you trying to achieve?

We can supply 02 simulators to prevent the ecu warning light coming on, but to map the Unichip for cruising etc means you need to switch the lamda's off, which (as far as I know) can only be done inside the standard ecu, and I don't know anyone that can do it.

Hello Mark,

You did warn me a while back when I discussed getting a supercharger that you liked to check the fuelling.

My rolling road engineer reckons there is more horsepower to be had with the Unichip Supercharger combination if the lambda sensors didn't stop the ECU under fuelling.

He recommended Lambda sensor and water injection.

What do you think????

I still don't really understand what you mean, but water injection injection will not affect the fuelling or give you any more power.

I never comment on what other tuners say, so I will leave you to make up your own mind based on the balance of probabilities :)

Thanks for the comments guys.

I will have a think about the situation
