If one was to try and data log the pids to replicate this table what pid/s would it need to create " data: Xxx milligrams " value

One would be - GM.main1q_dma
The other - Sae.rpm
Data value - ?????????

Anybody have any ideas ?

Is anyone able to figure out a pid to monitor the milligrams of airflow for this table ?

Anyone have a clue how to monitor the "milligram" data ?

Going to be a tough one, doubt it would be easy or very accurate but you may be able to make a calculated pid based off of airflow with the actual engine volume and map minus the expected flow through the maf for given cid and map pressures, i'm math stupid so I would not be able to offer much help with the pid. What are you trying to do anyways I only know a few settings for that table and it's either "0" or "maxed" pending the type of ecm?

Just trying to make the computer pass tests while having it blocked off.
