I don't remember reading the specifics, but have been reading a lot of other places and had a question about the erroneous formula

Basically right now it just does airflow/14.7 but doesn't actually check the ratio?

Assuming my premise is correct, what if it were divided by the output voltage from the o2 sensor(s) and normalized to 14.7 middle? Or would the same problem exist?

Is there an accurate sensor that puts information out over OBD that will work?
