    I had the same problem once. It ended up being a fuse. I just cant remember which one. But it cut power to the O2s

    Open up your scanner and go to Vehicle tab at top of screen and select Repoll make sure you connect to the vehicle first or it will be grayed out. Try that and see if it works

    Your car is in Open Loop due to a fault. It won't have any WB EQ feedback..... Find the fault, are there any codes?

    Also why do you have Throttle Angle Max=1 degree @ 1000rpm?
    Knock Retard is the reduction or prevention of knock by lowering ignition timing:

    (+) Adding Knock Retard = Reducing Timing. PCM is seeing knock.
    (--) Lowering Knock Retard = Increasing Timing. PCM isn't seeing knock.
