MSD Digital Multi-Retard Control 4704021-10-S 2A/1 and SFI 3The 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
