To tune an engine you should have at least a 4 gas analyzer CO, CO2, O2, HC, and get the exaust before the cat. I don't think a NOx analyzer would help much unless you have a dyno. You might want to call around and see if there are any shops in your area that have a dyno and an exaust analyzer. I belive the dynos around here charge between $100-150 for an hour.
If you just want to use a voltmeter and a O2 sensor just use the stock O2 sensor if you have one. All you need to do is hook your voltmeter up to the signal line and the ground wire if present if not then just ground the other end of your voltmeter to the engine. Most O2 sensors vary between 0V and 1V you want it to toggle above and below 0.450V if I remeber correctly it should be above 0.450V more than below but you still want it to toggle above and below 0.450V.
vas deferens: Do they check for NOx in Hawaii?
