MSD Digital HEI Module
MSD offers an all new Digital HEI Module and performance coil that
will fire up your stock HEI Distributor. The Module is a direct
plug-in for the 4-pin HEI module and will produce up to 7.5 amps of
current. This increased energy will continue through racing rpm
reaching 9,000 rpm!



The Digital Module is extremely accurate in its delivery of this
energy resulting in more accurate ignition timing. Another unique
feature is an adjustable rev limiter. You can dial in an engine
saving rev limit ranging from 5,000-10,000 rpm. The other unique
feature of this module is it’s patent pending technology that can
detect if an illegal traction control has been installed. For
street cars, you’ll never know this feature is there, but for
circle track racers that are breaking the rules, they’ll find
themselves with a low rpm limit activated! If a traction control
event is detected, the Digital HEI module will go into a rev limit
mode.



To get the most performance out of the Digital HEI Module, MSD
offers a performance Coil as well. This Coil drops right in place
of the original coil and fits under the stock coil cover.
