hey man, those pictures are murder, my browser times out before all are loaded, & that's on a dsl connection

tn6478, to do what your talking about, I'm asuming you want to use the pc instead of like one of those expensive controllers like the dakota digitals or air ride tech's setup.
this can be done like greenman said with relays, but you'll want to be able to have some sort of reference as to where the car is at any given time. for that you wil need a way to monitor the suspension, there are 2 ways of doing that, either monitoring air preassure for each port(easy) or actually monitoring vehicle height ( a bit more complicated, but better) this should be pretty easy to do really, but since you asked about "memory" you should realize that the fusion brain doesn't do anything without the pc up & communicating with it, so the suspension control will be dependant on the pc for the functionality your looking for.
you can still have the normal basic functions of the system though even when the pc is not up, it'll just be manual at that point, like any other "simple" air ride setup.
