Hi Tom,

Did you managed to reverse the hardware side of ignition control. I am only interested in the signal that pcm sends to ignition control module and what type of it is. Usually there is a dwell timing that goes to ICM. Does the pcm supplies voltage or just ground the icm pin, while grounded the coil charges and once the ground is removed the coil fires. I am just speculating. I think this was covered in other threads but can`t find it.

Thanks
