Okay so rescaling means exactly that. The maf table is 2 columns 1 is voltage and the other is a grams per second measurement of air.
If you change the diameter up or down of the housing that the MAF sensor sits in, that means the amount of air that is flowing through at any given voltage is going to be different based on that change. Rescaling means that you change the grams per second values so they are accurate again, and the ecu is able to calculate air/fuel accurately again.
