Hi guys,

Im new and have searched around a lot and chasing some more information. This seemed the topic most on point sorry for the thread dig.

Looking to replace both my vs ecotech v6 narrow band sensors with wide band. Whats involved to get it running?

Looking at using this with tuner pro setup eventually

Has anyone got this to work successfully. Guide for idiots would be helpful :)

you will need to setup the widebands analog outputs to simulate a normal narrowband, then simply wire each one into the computer where the narrowband would normally connect.

Thankyou mate really appreciate the help.

What I was trying to do was used wide band sensors without simulating arrow band. Is this possible?

you can but then the computer will not have the correct signal so will never do all the functions it relies on the narrowband for, ie. closed loop fuelling.

generally if you want to connect a wideband for tuning you put it in place of the narrow band and then remove it once finished, or add a second bung in the exhaust so you can have both in there, so the computer stays happy and you have the wideband as well.

having said that, most widebands have the function to simulate a narrowband so it should be able to do it .... and it still works as a wideband for tuning it just also outputs another signal that the computer can use for its narrowband operation.
