MSD 8975 Engine Timing Damper

Perfect for nitrous applications. Must be used with an MSD ignition system.;

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.;
