Anyone ever fitted an Air Fuel Ratio Sensor?

Hi, I have a tuned 2.0 8v with nitrous running fine but for peace of mine I was considering fitting an air fuel ratio sensor and gauge so I know if it starts to run lean.
Has anyone done this?

you'll want a wideband controller ideally as it'll display a much more useful range of information. the hard part is having a lambda boss welded into the downpipe, once thats done its a case of run some wires and spend a bit of money on the bits you need

I have one of these fitted to mine:

Thanks guys, Ade, the wideband sensor sold at demon tweaks says its supplied with a bosch sensor, would this be the lambda sensor you need to weld into your down pipe?  

Yes mate, it comes with a weld in boss and the Bosch lambda sensor. Get your friendly exhaust place to weld it in the down pipe.

Helpful too if you don't have a heavy right foot!  

Hey Hugh !!!

Helpful if you DO have a heavy right foot !!!

We don't want a lean mixture at high revs !!

I got one because I am paranoid !!
