MSD 8922 MSD DIS Coil Simulator

Works with Ford Modular Dual coil ignition systems and Late model Jeep with distributorless ignition systems, 1999 and later.;

In some instances when you install a DIS-4 Plus Ignition, the factory ECU may not be able to distinguish when the coil fires. This is the signal that is also responsible for firing the injectors (or the tachometer), which may cause a no-run situation.

The Distributorless Coil Simulator simulates the Original coil reluctor signal thus allowing the ECU to properly reluctor both the tach and fuel injection with the MSD DIS Ignition installed. In most cases, the Simulator plugs directly into the MSD's Harness.;
