RE: Efie running and scanning
Ah, ok. No problem.

The voltage is not significant for o2 sensors. By that I mean, how high it goes. o2 sensors work on a 2 valued logic. Either it's high or its low. The computer doesn't register how high it is, or how low it is. It just notes whether its above it's midpoint (about .45 volts) or below it. The Digital EFIE is designed to cheat towards being high more often than the o2 sensor signal sent to it. But the amplitude of the changes is not significant.

Compare that to wideband sensors which give the computer a curve of readings, each of which is a different air/fuel ratio.
