The MSD 6201 Digital 6A Ignition Control is a microprocessor-controlled, capacitive discharge ignition box engineered to maximize engine efficiency across the entire RPM range. Delivering multiple sparks up to 3,000 RPM, it ensures easy starts, a smooth idle, and crisp throttle response — then transitions to a single, sustained spark above 3,000 RPM that stays lit for up to 20° of crankshaft rotation for a complete burn of the air/fuel mixture in every cylinder.
Inside the Digital 6A, updated digital circuitry and efficient components drive over 530 primary volts to the coil with 135–145 mJ of spark energy per firing — all while drawing less current than older analog designs. The result is more power and reliability with a leaner current draw of just 0.7 amps per 1,000 RPM.
The low-profile housing shares the same bolt pattern as the traditional MSD 6AL, making it a direct upgrade. All wiring exits cleanly from one end of the unit through a sealed, locking connector for a professional, clutter-free installation. A built-in LED indicator simplifies system diagnostics at a glance.
