MSD Ignition Digital-6 Plus ignition controller

Universal Ignition Controller

The MSD Ignition Digital-6 Plus is a digital ignition controller built for four-, six- and eight-cylinder engines. It delivers programmable timing control for carbureted or EFI performance applications. The fully potted polyurethane housing protects internal electronics from vibration and moisture. An integrated LED display provides clear status feedback during setup and operation.

Upgrade From Analog Boxes

This unit replaces traditional analog ignition modules when precise step retard for nitrous or a two-step rev limiter for launch consistency is required. It accepts points, amplifiers and magnetic pickups, so existing trigger systems can be retained. The digital accuracy pays off when tuning demands repeatable timing curves that analog circuits cannot hold.

Drag And Street Builders

Racers needing consistent hole-shot rpm and nitrous timing control will benefit from the programmable features. Builders running distributorless or coil-per-cylinder setups that require direct ECU communication should look elsewhere, as this controller is designed for single-coil distributor ignition systems.
