Kaya nag design mga engineer ng Transistorized or IC type . Sa Mitsubishi ay Igniter IC ang tawag at sa Toyota naman ay Exciter IC naman. Since semiconductor mga ito ay walang nauupod na contact at mabilis pa ang switching nito... Dito lalo lumalakas ang induced high voltage ng ignition coil at hindi nag deteriorate sa high rpm.

So, mas malakas ang hatak ng engine na naka electronic ignition system.... Wala maintenance since hindi ito mechanical.... Same terminal pa rin ng ignition coil or - coil ang connection ng tachometer. So wala baguhin sa existing tachometer.
solid state ignition that still uses mechanical contacts, does get dirty contacts after some time. they have to be cleaned and adjusted periodically, although not as often as the traditional.
we know, because it bogged us down. "it was not as maintenance-free as we thought."
optical systems, however...
