Description:
MSD digital multi-retard timing controls provide four different stages of retard, along with an adjustable start retard feature--with no modules! These units use 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 degree. These circuits are thoroughly de-bounced 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 degrees, and a maximum of 20 degrees 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 degrees during cranking. Digital multi-retard timing controls can be used on 4, 6, or 8-cylinder engines, and must be used with an MSD ignition control.
