What RPM inputs are accepted?A magnetic, points or standard coil negative will work, but not a hall-effect 5V signal. The signal out of any MSD distributor or MSD Ignition Control Unit will suffice to supply an RPM signal for the Atomic. NOTE: An Ignition Control Unit is required with most applications.
