From: http://www.cnlperformance.com/MAF_info.php?section=14 wrote:The diameter of the MAF housing affects the velocity of the air which passes through the unit at a given amount of airflow volume. Smaller units have a higher velocity while larger diameter units have a lower airflow velocity. To achieve a MAF signal that is appropriate for larger fuel injectors, the voltage must be lowered by a corresponding percentage amount. This is easy to do with larger MAF housings, as the airspeed is naturally reduced even when the same calibration section (sample tube) is utilized.
Just some info to share with everyone for a sample taste of things I've learned and endured with this project.
