That depends what you are trying to do, what model of car you have and how modified your car is. Are you trying to find a fault? Tune a car? Check it's tune after modifying it? The information/data isn't much use having without knowing how to interperate it. For a start you could check that when the knock correction figure goes up the ignition timing figure goes down. The O2 figure should be swinging from about point two to about point eight, if it isn't then there is something wrong. If you load the motor up, or induce a miss by either letting an air leak into the intake or shorting out one spark plug lead, then the O2 should go to one extreem of it's range briefly and when it does, the A/F correction should give some positive on negative reading for a short while which should re-centre the O2 readings back to swinging as they are meant to. If that process doesn't work then you have a problem. To interperate and use the figures you are getting you really need to know how engines are tuned and how the ecu controls the car. If there is some specific question you have, ask it, and someone will answer I am sure.
