Porsche 944 Firing order
All 4 fuel injectors fire at one time.
They fire once every crank rotation.
They fire twice every cam rotation.
The 944 wiring diagram does show the injectors
are tied in pairs. Two DME pins are
used. What you do not see is the pins are connected inside the
DME. So all injectors fire as once.
