| Steve,
I almost understand what you're telling me. Bill Shultz commented on the Blue Mountain EFIS using the #1 injector for RPM. So, if the BMA EFIS is connected to the #1 injector lead, then it could be causing the over rich condition on that rotor. I'm not sure if I did that or not as my BMA RPM indicator has never worked. It has been many years since I installed the EFIS, so I don't recall if this was done or not. But this will be the next thing I will check.

Mark,
If a device is connected to the EC2 side of the primary injector of rotor 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 inductive spike for this injector rather than in a difference in the signal pulse width.
