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°. These circuits are thoroughly debounced and isolated for protection against Electro Magnetic Interference (EMI). There is also an innovative Magnetic Pickup Compensation circuit built-in to allow for rock steady timing with a variety of different mag pickups. 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.

Excellent for use on nitrous applications were you don't want to run retarded timing when the nitrous system isn't activated thereby giving up horsepower
