[QUOTE="jonboylaw, post: 385442, member: 17621"] Because that is required fro the MJ system to work. The MJ sends signals ot the EDIS which then calculates the dwell and sends out the firing signal to the coil pack. The EDIS needs to know the crank angle/RPM etc to work out when to fire the spark plugs. It then sends the RPM signal to the MJ which then returns a signal to set the correct advance. The EDIS will run in limp mode if the MJ goes down, but it must have a crank signal to know when to fire the plugs. Hope that is clear. [/QUOTE]
