Stock dizzy sensors is more than enough to go full sequential injection and 4 separate coil on plugs. You just can't do it with the stock ecu, as it has only one ignition channel. You need a stand alone or a separate ignition system like the ford edis. But again in this case you would need another crank trigger and the stock ecu will give an ignition related error, as there will be no ignition feedback signal. So either stock ecu and ignition, or standalone and whatever.
