    MSD 7555 Inductive Sync Pickup Kit

    To incorporate the Individual Cylinder Management functions of the Programmable Controls, a synchronization pickup must be installed to notify the ignition when the number one cylinder is firing. This Inductive Sync Pickup easily installs onto the number one spark plug wire, senses the trigger signal, then sends this information to the ignition through a fiber optic cable. By using a fiber optic cable, there is no chance of EMI or interference.

    MSD 7555 Inductive Sync Pickup Kit Features:

    • Designed for 7 Series Programmable Ignition Controls
    • Allows for cylinder-to-cylinder timing control on Power Grid and Digital Programmable Ignitions

    MSD 7555 Inductive Sync Pickup Kit Includes:

    • (1) Inductive Sync Pickup
    • (1) 12 feet of Fiber Optic Cable with Sleeve
    • (1) Tie Wrap
    • No Timing Compromises

      Ignition timing is always a compromise between cylinders. The dynamics of air and fuel flow into each cylinder is never exactly the same no matter how much machining magic has been done. This has always caused top engine builders to compromise their ignition timing. With the Programmable 7-Series Race Ignition Boxes advanced Individual Cylinder Management system and other exact timing programs, you will never need to compromise again.
