Testing coils on a coil over plug system?

So you're running an MSD Ign. and a seperate controller for fuel? And yes they are partially right... if it has a cam sync LED that blinks it is seeing the signal however a hall sensor is easily checked, you could even use a DVOM if it has a fast enough sample rate, most switch from 0 to 5 volts. Adger had stated that you are seeing the engine go lean during the event is this the case and if so what reading are you getting?
