gms/sec airflow?

can someone help me to figure the airflow calculations in the $0D code? for example. at 2000rpm and 40kpa, what airflow is being used for the airflow specific tables like o2 boundary and pid tables? the tables start at 0 and go to 128.

thanks.

If you need it for tuning the best bet is to grab it from the ALDL stream. That way you know for sure what value the ECM is using.

Re: gms/sec airflow?

Like RBob said, its easier to datalog. The base airflow is located at $0255 in the RAM and goes from 0-256 grams per second. You would have to edit the mode 0 ALDL transmit table to include it, or switch scan modes to get a transmit table that has the airflow included in the list of items transmitted. Easier to just add it into the mode 0 table.
