A POSITIVE OUTCOME ON YOUR DUI

Many vintage and performance vehicle owners are looking for an alternative ignition solution to a point type distributor and traditional coil.

One of the best solutions out there is a High Energy Ignition type distributor (or HEI). Not only do they produce over 50,000 volts of output, but they also clean up the engine compartment because the coil is incorporated into the distributor cap. HEIs are very easy to wire and require minimal maintenance. Davis Unified Ignition (or DUI) is a standard in the HEI world. They have a large selection of distributors for several makes and models. They also make coils for coil-on-plug applications, performance ignition coils, plug wire kits, batteries, and even one-wire alternators. Our 1949 CJ-3A had a Chevy 2.5 motor put in it sometime in the ‘70s. We were having some drivability issues, so we replaced and adjusted the points. We also did a few other small things ignition related. The Jeep had a horrible flat spot under acceleration, which we narrowed down to a vacuum advance problem. Not wanting to throw good money after bad, we upgraded to a DUI unit and their Live Wire wire set. (Figure 1)
