    MSD's Digital Multi-Retard eliminates the need for a module by using a high speed RISC micro-controller to direct the timing functions while allowing for (4) different stages of retard and an adjustable start/retard feature for easier starting. This RISC processor can make extremely quick adjustments to the timing signals while still keeping accuracy to within 1°. These circuits are thoroughly debounced and isolated for protection against Electro-Magnetic Interference (EMI). There is also a Magnetic Pickup Compensation circuit added to allow perfect timing with a variety of magnetic pickup triggers. The Multi-Retard is perfect for multi-stage nitrous applications, and each stage can be activated independently or together for a total sum of retards. Each stage is adjustable from 0°-9° and the maximum amount of retard is 20°. The unit can be programmed for 5°, 10°, 15° or 20° of retard during starting.

    Features:
  • (4) stages of retard
  • Magnetic pick-up compensation circuit
  • Adjustable start retard
  • Great for nitrous use

    Notes:
  • Can be used on 4, 6, or 8-cylinder engines
  • Must be used with an MSD Ignition Control
  • Not legal for sale or use on pollution-controlled vehicles
