FED ECU O2 Voltage

This video shows monitoring of the O2 sensor output voltage on a Federal model 1993 Honda Civic VX with a D15Z1 engine. As described on this webpage: http://ecomodder.com/forum/showthread.php/vx-info-warning-lots-info-23.html

Pins D14 and D16 of the Federal model ECU (serial P07-A00) are hooked up to a digital volt meter, which you see in the foreground, and the tachometer is sortof visible in the background (sorry about the quality, I shot this at night).

The engine is started cold just before the beginning of the video. Lean burn is shown as a voltage above 0, and a lower air:fuel ratio is being used when the voltage drops into negative numbers.
