Default Datamaster 02 locations?

i have a 94 vette. The right 02 is reading bad in datamaster. I see one sensor on driver side ( left). And two sensors on passenger side, one before cat and after. Is data master reading the precat sensor on the right? Is the sensor after the cat even an 02 sensor? Thanks

Yes it is reading both precat o2 sensors. Most think the one post cat sensor is nonfunctional.
