Performance Distributors now offers the D.U.I. (Davis Unified Ignition) for AMC
engines. The AMC D.U.I. is a one-piece ignition system with the coil in the
distributor cap and the module inside the distributor. The D.U.I. Coil produces
50,000 volts and allows spark plug gaps to be opened up to .050" - .055". The
Performance Distributors Dyna-Module has more electronic dwell time in it to give
the coil more saturation time and produce a hotter spark. The D.U.I. distributor
eliminates the ballast resistor that is used on the stock AMC ignition system. This
will allow full alternator voltage through the ignition system and will provide a stronger
spark and more power.
Each D.U.I. Distributor is tuned on a distributor machine based on the specs of the
engine. A super smooth advance curve will eliminate engine damaging detonation
and give instant throttle response. The unit is polished and lubed as it is assembled
making it a true blueprinted distributor.
The AMC D.U.I. is a real work of craftsmanship and although it is uniquely designed,
replacement parts are easy to find. High Energy Ignition (H.E.I.) replacement parts
will fit right on the D.U.I. These parts can be found at any local auto parts store.

Protect your engine from over revving with the DUI Rev Limiter. The D.U.I. Rev Limiter
drops one cylinder at a time very smoothly. This prevents fuel from loading up on the
plugs. This also avoids backfires and engine damage. Set your RPM limit with plug-in
modules. A 6000, 7000 and 8000 RPM module is included with the rev limiter. Other
RPM increment modules are available separately if needed. This unit works great with
all of our DUI distributors.
