air fuel signal info?

[kapowered]

Does anyone know what the voltage range is from the KA24DE's O2 signal, and what voltages correspond to what A/f ratios? Also I may be wrong, but aren't their two o2 sensors, one front and one rear, what are the differences between the two? Any info would be helpful.

there are 2 sensors on S14's. S13's have one. The one you want to get a signal from is the first one, located on the header.

From www.autometer.com:

LEAN RANGE: Four red LED's (.050 to .249V)
STOICHIOMETRIC RANGE: Ten yellow LED's (.250 to .749V)
RICH RANGE: Six green LED's (.750 to 1.000V)
