where did you connect the wire,
from the ECU or at the O2 sensor??
or before the plug at the O2 sensor?

After the plug on the white wire.

before the plug on the ecu side of the wire.. The instructions tell you not to plug it into the o2 sensor wires

At the ECU were it would probably be most acurate since it is coming from the sesor to the ECU.
