HEI ignition conversion

Mrmopartech said

So lets see here,I guess the HEI module and the HEI coil out of the cap that I had run for years on my mopar with no ballast and ran from straight off the ignition switch with no problems is just a nother clouded dream cause by the canadian beer,I should be drinking the water down american beer.So the D.U.I. that is sold is another dream that is caused by the beer,and runs the complete OEM GM cap,coil,rotor,and 12Volt power from the ignition,just like the GM cars with no ballast,and is used on small blocks.I guess its time to switch to Jack daniels,never had those flash back problems,mrmopartech

You were not paying attention to my first post on this subject!!!!!!!

A GM HEI ignition system does not use a ballast resistor because the coil in cap is an E-core design that does not have the over heating issues associate with an oil filled coil, the system was designed to operate without the ballast. The DUI system is an adaptation of the GM design. I have no idea whether the version using a standard mopar cap with the external module and remote coil requires a ballast or not but it is provided with their coil so I am going to assume the coil is designed to operate a full battery voltage if the instructions state not to use it.

The schematics I have seen of the GM HEI module are the same basic design as the mopar ECU and the early Ford system, an electronic switch that replaces the mechanical switch called points.

So I repeat using an GM HEI module to trigger a mopar ignition system does not eliminate the need for a ballast resistor. If your goal is to eliminate the ballast resistor just purchase a coil that was designed to operate without one, no need to swap modules.
