The Digital Multi-Retard provides four different stages of retard along with an adjustable start retard feature - all of this with no modules! The MSD Multi-Retard uses a high speed RISC microcontroller to direct the timing functions. This controller can make ex­tremely quick compensations to the timing while maintaining accuracy to within 1°. There is also an innovative Magnetic Pick-Up Compensation cir­cuit built-in to allow for rock-steady timing with a variety of different mag pick-ups. There are four separate retard stages that can be activated independently or together for a to­tal sum of retards. Each stage is adjustable from 0° - 9° and a maximum of 20° of retard can be pulled out. On top of these great features, there is also an optional start retard circuit that can be programmed to retard the timing 5°, 10°, 15° or 20° during cranking. The Digital Multi-Retard can be used on 4, 6 or 8-cylinder engines and must be used with an MSD Ignition Control.

Features:

  • Four stages of retard
  • Magnetic pick-up compensation circuit
  • Adjustable start retard
