The Three Stage Retard Control retards ignition timing in three separate, cumulative stages — for example, activating one stage for nitrous, another at top end for more mph, with a third module left over for dual-stage nitrous systems. It connects easily to an MSD 6, SCI, 7, 8, or 10 Series ignition and can be triggered from points, electronic ignitions, crank triggers, or magnetic pickup distributors, and ships with 2°, 3°, and 4° modules.
