The O2 sensor interacts with the amount of oxygen in the exhaust stream and
produces its own voltage form 0 to 1 volt, if I remember correctly, less
than 0.5v indicates a rich fuel mixture (greater than 14.7:1 air/fuel ratio)
& if the voltage is greater than 0.5v it indicates a lean mixture. I would
think it would be fairly easy for someone to create an o2 emulator, all you
would need is a clean 1 volt DC source through a rheostat. Using resistors
you should be able to reduce 12vDC (13.5vDC approx. charging voltage) down
to 1vDC into a rheostat (like a car radio volume control) & through a low
voltage meter (so you could monitor the voltage). More voltage = More fuel =
more power (to a point). just a thought ;-)

I'm really surprised someone hasn't made (or made available) an 02 sensor
emulator - i.e., an electronic gadget you can wire into your 02 sensor
harness to send artificial readings to the computer, thus eliminating the
actual 02 sensor altogether. Seems like this would be an easy thing for an
electrical engineer to build - anyone remember what the 02 sensor readings
are under 'normal' conditions? I think it's a rapid fluctuation from -1 to
+1 or something like that......
