Sonny,

You CANNOT connect the WBO2 directly to the Flashscan unit, the WBO2 needs to be connected up to a WBO2 controller.
Some brands that spring to mind are the LM1, the PLX range.
Both these units have a voltage output that indicates the AFR, this is what you need to connect into Flashscan.

Cheers,
Ross

The links above will point you in the right direction. You need a translator so to speak (WB interface/box) that interprets the data comming for the actual sensor. Most have an analog output that is connected to the cable for logging. Have you read the manual? I am pretty sire this information is contained somewhere in there

You not only need hardware to be able to interpret the voltage (with the interface system) and send it to your Efilive system, but you need to control the temperature of the heater in the sensor (some run up to something like 600* C, IIRC). Check out the techedge.com.au site to see how these work.
