Scalars for o2 swing points, in $6E?

I was wonder if there were scalars, for the 3 swing points, (idling or low %TPS)? I have the 3 tables of course, which are for NOT idling. Compared to $8D, S_AUJP, which has tables AND the scalars, for the swing points. Just asking.....

No o2 value distinction made for TPS and MPH like in $8d. Only 1 swing point table. No Scalars. Most everything based on LV8 Load which is essentially Airflow * RPM.

That's what I figured, just wanted someone to confirm it. Thanks for looking into it. The $6E seems to be much less complicated than the $8D stuff.

Theres 4 tables that you might play with. Closed loop rich lean offset, upper and lower zero reference tables and fast o2 rich lean offset. They are versus grams airflow so at idle you can adjust the milivolts. I know i played with them on my big cammed 383 to target a different air fuel ratio to compensate for overlap but cant recall what i did exactly. Need to find that bin

O I surely know about them 4 tables....I will be changing them for sure. I was just asking if there were scalars as well, like in $8D.
