closed loop mode vs airflow question im confused on this table, i changed my map boundary up a little higher, to 37 and i was looking at this table.
from what i can see, the top part is g/sec and the bottom is the airflow mode or maybe fuel trim cell, hell i really dont know, thats why im asking and to see if it even needs adjustment. let me knwo what it does, the help file isnt too much help on explaining this

thanks that was actually something ken emailed to me a few days ago, i was asking about that stuff for injectors.
the table im asking about has to deal with the airflow cells, although that write up is great, it doesnt really cover what im looking for

That table shifts/squeezes the airflow range down to a smaller size axis.
2D tables are always set up as:
Table returned value vs. Variable
In this case the airflow variable is used on the lookup table to return a number. This means the airflow range of 0-320gm/s will be divided into 80 table locations.
That gives you 4gm/s per row. Returned table value can be from 0-16. This is your "Airflow Mode".
Now take your returned table (0-16) value and use it as the new axis against all of the closed loop vs Ariflow mode tables.
You can work it forwards or backwards to see what the airflow is going to be.

ahhhhhh i see so all the other tables use this table to determine the airflow.
so say my proportional entries, cell 14, well i see thats airflow of 40g/sec and i see my o2 sensors arent switching like they should be, so i adjust the number in cell 14? just makes the tables smaller and easier to read pretty much?? so these numbers arent AS significant, just a look up table?
