Ralph,
I don't know about that.
My BME102 will idle OK with a measured ignition voltage of 4.5.
When I increase the RPM, the voltage drops to around 4.2 and the unit starts to cause the engine to miss. I have had the unit in for service and know it is working good. WHen I charge the pack the problems go away. This I KNOW.

If what you are saying is true (and I dojn't doubt you), then I would definately like to find out why my engine and ignition operates differently.
