Most if not all controllers allow for an anolog signal so you can get an A/F reading as well as the sensor itself sending a signal to your ECU. (innovative may be different? but there should be a way)
Your ECU gets the narrow signal but you get the reading. Narrow band O2 sensors reading 14.7:1 have an equivalent voltage of .5V, between rich and lean you'll see 0.3V~0.7V.
Under high load (WOT) the ECU will ignore the narrowband signal and run in open loop and the range there tends to be .85V~.96V
14.7 = .50V
14.6 = .60V
14.5 = .70V
13.5 = .85V
13.0 = .92V
12.0 = .95V
As far as where to hook it up in your/our ECU:

Our cars run rich when cranking, warming up (idle), under medium load when cold, warm is rich and lean, acceleration rich, heavy load rich, deceleration=fuel cut, rich and lean when the throttle valve is fully closed, and fuel cut above 6,300 rpm.
PS- Use your existing bung for a backpressure tester:
