Originally posted by RedSVT: The DSM guy's that had trouble with the idle are trying to use blow off valves that dump into the atmosphere. DSM's ARE MAF controled,with a MAF system the blow off valve MUST dump back into the system after the MAF. With a Speed Density system you can blow off into the atmosphere.  He is right there. The DSM ECU cannot hanlde atmosphere dumps as it has already ":counted" the air coming in and on shifts the dumped air dramatically decreases the A/F ratio (richer) and causes the engine to stumble. The DSM's use a Karman Vortex type of MAF. It counts eddies in the airflow to calculate the mass of air entering the engine. The Apex S-AFC is compatible with different types of Air Flow meters, I just hope that the Ford style is one of them. I am thinking it should work. Give it a try Mark. I wish I still had mine! :rolleyes:
