if you want to build a decent sensor you'll need a 5 wire wide-band lambda sensor which are £60.00 just for the sensor.. then they need fancy electronics to control.

Oh

I guess I'll have to look into this in more detail if I'm to pursue it then. It could well end up matching or exceeding the cost of a dedicated emissions analyser.

Thanks for the heads up Neo.

It will do!!

Check out there, they supply a lot of DIY kit stuff for Lambda stuff.

The 5 wire wideband (that can be used for fine tuning of mixture) needs a dedicated cpu to control it as the heating element etc is very delicate and it needs to be controlled properly else it'll die.

You can make a simple lambda thing to say rich / lean using some LEDS and a £1 chip, but it's not very precise.

WB02 do some very high quality wideband gear, and even a moto specific version (small size). Looking to get one soon that has data logging abilities.

If you don't need or want logging ability then there are cheaper options:
