Q & A

What's in the Box

For a crisper, smoother running engine, replace your stock HEI module with the Dyna-Mod. The Dyna-Mod has more "electronic dwell" in it to provide more coil saturation time. The additional saturation time allows the coil to produce a more intense spark. All D.U.I. distributors are built with this module.

Fits 1974-Up (w/o computer) GM HEI distributors.

what is the amps on this dui module?


August 11, 2011
According to the manufacturer the amp of the module itself is 0.5. This has no relation to the actual output of coil and spark generated by the longer saturation time of the coil. With this type of module it allows the coil to generate a hotter spark delivered to the plugs.
