MSD Single Cylinder Programmable Ignition Boxes

These MSD single cylinder programmable ignition boxes are designed for use on a variety of single cylinder motorcycle type 2 and 4-stroke engines. They deliver increased spark energy and voltage through the entire rpm range and provides the user with a variety of programmable functions including mapping two timing curves, setting a launch rpm limit, using TPS for timing control and more. The MSD single cylinder programmable ignition boxes gives you control over the timing functions of your engine. There are two timing curves that can be switched between through wire activation. Both timing maps allow up to 20 points to be plotted in 100 rpm and 1° increments from 0 – 16,000 rpm and 0-50°. The Brown/White wire is used to switch between Curve A and B. When it is connected to ground, Curve B is selected. These curves can also be set up relative to TPS voltage input from closed throttle to Wide Open Throttle. Show Less
