I'am finally check out all "breakdown point" ,so I got some question in this picture,between the "MSII"and the "Bosch-124"
But,I stuck on this process,How to elimination the "breakdown point".
Question:The coil voltage should between "12V-0V" to charge and discharge,However,the coil voltage keep 12V forever.......
MSII's Version:2357-C
Megasquirt-2ECU
PCB V3.57


Bosch-124's diagram


Right


Wrong

On a scope, the coil negative should switch from +12v to approx 0v when the sensor causes the ignition ECU to switch. More of less like points do. If it's not switching with the engine turning, likely a faulty sensor or ignition ECU.
