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 micro controller 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 to6AL 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.
