MSD Ignition Controller, 6 MOD, 2-Step Rev Limiter, Vacuum Advance Curve, Step Retard, Plug N Play, Ford 4.6L / 5.4L

New technology to go old school! When you retro-fit a Ford 4.6L or 5.4L (SOHC/DOHC) with a carbureted intake manifold, you'll need this new Controller to handle the ignition chores. The Controller plugs into the coil packs and sensors of the engine for a direct installation. From a PC, using our Pro-Data+ software, you can program a custom timing curve, a step retard, two step rev limiter and even a vacuum advance. A great system for street rods and retro muscle cars.
