You need to go into ; [setup],[auxillary] and change the values in AN1-AN2 to whats in the picture and connect the pos and neg outputs to the AN1 and AN2 connectors.
Danny, the O2 feedback has nothing to do with logging the external data.
The O2 feedback does just what it says, the ecu uses (or not if it's switched off) the feedback from the lambda sensor to run the engine , when in closed loop, to whatever you have set it to.
As standard it's set to 14.7 but you can change it to whatever you like.
