Geez, I really ought to proofread a little better... :(

What I meant to say, is that I have NOT found a chart relating the sensor
voltage to air-fuel ratio.  I have sinse read a lister's reply, though,
stating that the sensor is notoriously inaccurate when deviating too far
from 0.5v, so I guess there is no way to determine when the A:F ratio is
12.6:1, based on the oxygen sensor or pressure actuator current.
