If you went megasquirt w/edis, you can use the ford edis ignition stuff. You can get the ignitor, the coilpack and everything needed basicly off... I forget the name, the mercury version of the escort...

The megasquirt includes a map sensor, good to about 1 bar i believe. pretty neat deal IMO... There's suppose to be a new version of megasquirt comming out pretty soon (ultra megasquirt I think) that includes the ignition stuff (the edis is more of hack on the current version) and WB o2!
