I can only speak for HP tuners.
It should be in your primary table and scanner automatically.

If its not,Click on the display table, Right click insert on an empty area, your PIDs will pop up, Click on engine, then airflow, then double click on mass air flow ( hz), if its actively working, it will show up in red in the PIDs ( and in black on your primary table)

Then you have to build it to your configuration

check that your not in Khz

Yeah, you should be able to select it from the PID list.
