Really quick question - clarification purposes

[TheKingPin]

ok - in order for smanager to show the a/f ratios - i need to hook up the wideband; however, will I have to hit the datalogging button for it to display the a/f ratios? or will it automatically read from the o2 sensor?

For information purposes - i have a 94 prelude h22a.
The s300 is installed in a p28 ecu.

Also, will i have to have it in closed loop operation?.......?

to get any information you must be datalogging.
