Known good primary & secondary ignition waveform PICO
Anyone have a Pico waveform of the primary and secondary ignition voltage for the above vehicle?
The first and second good captures are from a 2016 Charger 5.7. I am scoping 3 COP primary coil winding voltages during a 1600 rpm brake torque. The third capture is from a Charger 5.7 and it only misfired under hard acceleration. CH B is the starter amps. CH C is a pressure transducer in the intake and it shows 1 cylinder with a poor intake stroke vacuum pull. You can use the COP extension…
Their is multiple cylinder issues. I wanted to make sure I was not getting any variables and didn't want to trust even a none misfiring cylinder at this time.
Ray - What was the cause of failure on the 2016 Charger ?
The customer did not want to spend the money to remove the valve cover to check the valve train.
