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

From what I understand, this era of gm cars are fitted with "narrowband" o2 sensor, and there is no direct scale from the o2 voltage reading shown by the ecu to either forms of afr. Like mentioned above, .45 volts is "stoich," and when it is around .85, that should be somewhere around 13:1.
