It's the voltage on the 02 sensor as reported in the software. .450 is stoic
Target on NA is like .850 wot in PE or power enrichment mode.
A lot of tuners using the HP Tuners logging set up an Analog input from another wide band for a better Air Fuel ratio log.
Older factory ECU's are narrow band 02 sensors. . More modern are wide bands
