The Zipper’s Ignition System for the carburetor-equipped Twin Cam® and 2004-2006 XL engines offers the user many options for setting up the ignition system for optimum performance. Externally, the module is adjustable through 5 switches (face-mounted for easy access). These switches can be used to control operating modes including multi-spark, rev limit (in 100 RPM increments), initial timing setting and a selection of ignition advance slopes. These advance curves adjust timing not only by engine RPM, but also through engine load to help control detonation or pinging, a common occurrence in performance-modified engines. The module plugs into the factory harness and recognizes all factory sensors; it communicates diagnostic information such as failed sensors or low/high battery voltage to the rider by blinking codes on the factory ‘check engine’ LED. Designed for use with the factory coil.

The module is also programmable with a laptop or standard PC through the factory diagnostic connector port. Advanced users will be able to program a custom advance curve with up to 128 different adjustment points; you can also adjust rear cylinder timing offset, as well as set and lock initial timing and RPM limits though the software. An exclusive feature is the ability to set the system up to delay the ignition fire (from 0 to 3 revolutions) to aid starting of large displacement or high compression engines. A cable and software is required for connection between the diagnostic port and the computer (purchase separately).
