why would that affect MAF scaling?
as long as the diameter of the pipe the MAF is in is the same as stock and air flows through it smoothly, it will still calculate the correct airflow no matter what mods are done before and after the pipe?
this gets brought up all the time.. and no-one has ever provided a decent response as to my point above..?
If someone can point out the issues with my logic, let me know
-the MAF measures a flow rate,
-if you de-restrict the flow-path you can increase the flow-rate into the engine...
-but the MAF will still measure that change in flow-rate. that's it's primary function. to measure the airspeed through the MAF pipe
-as long as you keep the pipe size that the MAF is in the same (diameter) the flow-rate of air (volume or mass/sec) at a particular velocity (speed) you will always come out with the same result. (assuming constant density- air density is corrected by IAT and Atmo Corrections)
-faster air-speed cools the hotwire in the MAF more and thus results in a different voltage compared with a slower airspeed.
-as long as the pipe diameter is the same the calculation for Mass Airflow vs airspeed will always be equal
