Hi guys does anyone on here have one and would it be worth it from a tuning point of view?.

I am not sure what they cost but I have the motor out and it would be easy to plumb into the exhaust.

Opinions?

thanks all

It depends on the place where you have your car dynoed.
most just use a sensor in the back of the exhaust.
some weld and screw a fitting in up the front(i have the nuts to weld on if need be)
Or you can buy a simple mixture meter and plumb that in

I've got an oxygen sensor along with a Air fuel mixture guage. Pretty pointless really. I needed another guage to go along side my equally pointless boost guage.

I wouldn't bother from a tuning point of view. From a fun point of view, yeah why not. Sensors are cheap off eBay or similiar, same with guages. But don't expect them to be all that accurate, more of an indicator as to whether you are rich or lean under load.

I think this is what i am talking about.

How about from a backyard tuning point of view?

It's very useful as a tuning tool, I used a wide band unit mounted just after the turbo (see the bung in the pipe below) and checked the plug colours for mixture distribution during the initial engine tuning. Obviously I have it out most of the time as the wiring clutters up the engine bay.

You can get units that screw up the pipe at the back, but its cheaper to get a permanant mount like the one I've got.

what type of sensor you mean?
the cheap narrow band? will bring you close to what your engine wants, but this sensor can not be precise by design.
to get it spot on you will need the wideband type, a bit expensive and needs a controller, but can show the A/F ratio very precise.

If you doing it for tuning reasons you need to get a bosch wide band sensor or the bosch motorsport version which you can use with leaded fuel and also you need a good air/fuel ratio meter and when i mean good meter i dont mean a cheap a/f gauge from repco/super crap/autobarn that has leds flashing back and foward. Most fast a/f meters start from the $700 mark and work there way up to the motec meter which is around $2000

Dont waste your time with a cheap narrow band version.
Get a wide band as mentioned (if you have the $$$$)
Its a precise instrument...

ALSO

Note that different fuels require different sensor... if you run them with the wrong fuel they destroy them. Eg/ Race fuel, AV Gas, etc are different to a PULP sensor.

Not a cheap tuning tool...

For wide band sensors have a look at these http://wbo2.com/

There are also many more available on ebay. Most brands can be purchased overseas and shipped here heaps cheaper than you can buy here.

thankyou steve, thats what I was looking for.
