I have two electric motors, one 0 till 550 rpm and one 10.000 till 30.000
Test with both motors the sparks are very strong and regular on the scoop, no hickups.
I've to test the pcb with 0 till 20.000 rpm, but I can do this only at my work.(tomorrow)
My variable powersource have only 1 output and I use this to the pcb, so I can't putt a motor on it.

Update 09-jan-2006
PCB (CDI) tested - 0 till 30.000 rpm......great, no problems !!!!
Puls between timerboard and powerboard are egual, no *lost* sparks.
Dwell = 1 ms

CU, Rob
