Air/fuel ratio kit

[Craig]

I have seen these before, but can't find it again, basiucally it is a diy kit that looks like this

Anybody know where I can get one?

 

[Ed]

I have a K&N AFR meter you can buy if your interested?

Its £184 RRP, I want £100 and it has a brand new sensor.

Prob not made my point clear, I have seen a DIY kit that is a fraction fo that price, so I was hoping to save a few quid...

 

[Ed]

Ahh ok, I expect there are diagrams somewhere. I've never looked.

Ta Pete, fancy making me one

 

[Craig]

Hmm looks like I need a wideband lambda, true or false?

 

[Retepetsir]

I'm not sure, best to get Ed to answer that I would have thought! Anyway, that one measures between 0 and 1v, so you need to find out the range of the K11 lambda first

I wouldnt mind making one, as long as I could get the parts. I might nab one as well!

 

[Ed]

Wideband lambda sensors are much more complex to make. This is a narrow band one, and although not as precise, still a very usefull tool. In a perfect world if you plan to do mapping you need wideband. If your just monitoring narrowband will do for most things.

Yeah I suppose that narrowband will be all good forthe meantime, E-manage won't need wideband will it?
