A little info.... If you ever wanted to know exactly why it bounces around at cruising and is rich at full throttle than this is for you
During cruising the computer is in "closed loop" as far as the fuel trim meaning it is a preset fuel curve. At WOT the computer actually controls the curve by the voltage it reads from the o2 sensor.
With the "blinky light" gauge it is almost impossible to tune it to an exact voltage, (I think it reads between .75 and 1.00 in .05 increments) but there is someone who has putzed around with those type of gauges to make them read in like .01 increments but don't have the link right now.
