Mark,

 

If a device is connected to the EC2 side of the primary injector of roto= r 1 and this device has diode protection from the inductive spike produced = by the injector winding, then this injector will deliver more fuel than the= injector pulse width would indicate.  The appearance on the O-scope would more evident in the lack of an inducti= ve spike for this injector rather than in a difference in the signal p= ulse width.
