	Don't count on it...
	Many ECUs check for a voltage swing on the oxgen sensor to
make sure it's connected, warmed and functioning properly.  If you just
give it a straight voltage reading it will most likely go open loop and
generate an error code.

	The temperature sensor is a work around.  If you fool the ECU into
thinking that the engine is cold, it should allow a richer "cold" mixture
(assuming that that's your goal)

	What type of FI are you trying to play with?
