Where does the "airspeed calibration" adjustment come from?

Can anyone help tell me where in
the aircraft CFG etc the adjustment values for the Airspeed Calibration come
from? The original programmer that did this is AWOL and we can’t find where in
the code the ‘offset’ and ‘scale’ for the ASI have been programmed. Any advice
