I've built a Tech Edge unit to interface a wideband Lambda sensor with my
MegaSquirt. Neither of which is actually fitted to the car yet as I want
to make sure everything works properly before doing so. 
According to the software everything is ok, I've flashed in the latest
version and it calibrates in free air ok etc - but I'd like to check it
further, as I have suspicions everything isn't quite correct.

What would be an easy way of checking it's actually working? I fitted the
sensor in a large tin coffee can lid and lit a candle inside. The O2
reading didn't vary as the candle used up the oxygen and guttered.

I've tried joining the appropriate forum for this device, but didn't get
the email needed to initialise the membership. It says to contact the
administrator if you have problems, but the link given only works if you
are a member...

Stick it up an exhaust pipe?

Finally found an answer. Free air has so much oxygen it's off the scale -
even although that's how you calibrate it.

You hold an unlit gas lighter under it - and it should change from off the
scale weak to off the scale rich.
