I have only read a little about tuning the later model Mustangs etc. My system is EEC IV out of a 1990 Mustang that was auto. So it is not OBD II and retaining a MAF system the computer should take changes easier than Speed Density? My worked AOD gets no input from the computer, only the TV cable. I did use a VSS sensor which does send a signal to the computer showing road speed. From what I could find the VSS is used for controlling the EGR functions and in a EGR delete car you should still use it to prevent stalling???? I need too do more research on the VSS and if I had the money I would start with a slightly larger (new) MAF just because.
