Inductive Spark Plug Wire Sync Kit
  • For Use with 7-Series Programmable Ignition Controls
  • MSD Ignition 7555 Details


    In order to incorporate the Individual Cylinder Management functions of the Programmable Controls, a synchronization pickup must be used so the ignition knows when the number one cylinder is firing. This pickup simply installs to the number one spark plug wire and senses the trigger signal and sends this information to the ignition through a fiber optic cable. By using a fiber optic cable, there is absolutely no chance of EMI or interference.

    With MSD's race winning experience and performance ignition knowledge, the Programmable Digital-7 is THE ignition control.

    No Timing Compromises
    Ignition timing is always a compromise between cylinders. The dynamics of the flow of air and fuel 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 Digital-7's advanced Individual Cylinder Management system and other exact timing programs you will never need to compromise again.

  • ICM Timing Control: Adjust the ignition timing in each cylinder Program up to 5° of timing retard into each individual cylinder in 0.1° increments.

  • Run Curve: Plot a timing curve in 0.1° per 100 RPM throughout the entire rpm range of your engine.

  • Launch Curve: Program a timing curve exclusively for the launch If the starting line conditions are less than adequate, you can set a completely different curve for the launch.

  • Launch Retard: Retard the timing up to 15° for 0-2.5 seconds after you launch the car.

  • Step Retard: Three steps of retard that can be activated with nitrous solenoids or switches.

  • Gear Retard: Program a timing retard up to 5° with every gear change.

  • Start Retard: Ease engine cranking with an adjustable retard during start up.

  • Traction Control Detection: The TCD monitors the magnetic pick-up input signal and if it senses that the signal has been modified, it will set a trouble code and flash indicating that traction control has been detected.

    No other ignition system comes close to matching the output power and the Individual Cylinder Management timing system of the Programmable Ignition. To effectively handle all of the ignition's tasks, a 15 MHz microcontroller, reviews, manages and analyzes every trigger signal up to 15,000,000 instructions per second Capacitive discharge circuits combined with an IGBT Coil driver deliver incredible cylinder pressures. Below 3,300 there is of course MSD's powerful series of multiple sparks. This spark series burns in the cylinder of over 20° of crankshaft rotation resulting in improved combustion for a smooth idle, great throttle response and increased power.

    RPM Controls
    Monitoring the engine's RPM allows you to set shift light points, activation points and rev limits. The Programmable Digital-7 has MSD proven Soft Touch rev limiting controls built in and lets you program several RPM features.

  • Three Step Rev Control: Program three rev limits in 100 RPM increments for burnout, launch and overrev protection.

  • Shift Light: Program a different RPM setting for each gear change for up to six gears.

  • RPM Activated Window Switch: Activate a circuit at an adjustable RPM such as a nitrous solenoid, then set another RPM level to deactivate the same circuit.

    Easy Programming
    Don't let all of these accessories and adjustments worry you. MSD engineers developed two very useful and easy ways for you to program the ignition. You can use the hand held programmer or MSD's Pro-Data+ Software package on your PC. The Programmable Digital-7 Ignition Control can be triggered with a points/ECU trigger, magnetic pickup in a distributor or a non-magnetic pickup of a crank trigger. There is even a mag pickup compensation adjustment for absolute trigger accuracy The single unit is fully potted for vibration protection and is easy to mount. It can be used on 4, 6 or 8-cylinder engines and is supplied with the Pro-Data+ software, PC harness, vibration mounts, wiring and thorough instructions.

    Note: MSD 7-Series Ignitions are not compatible with distributorless systems.

    WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.


    WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
