2000-HDE PC-Programmable Digital Ignition Module

A plug-in upgrade to the electronic advance ignition found on late model Harleys, these ignitions are micro-computer controlled, generating extremely accurate control over the entire ignition process; Allow riders to tailor the advance curve and rev limiter to the specific needs of their particular engine; four built-in advance curves cover the needs of stock to highly modified engines over a variety of operating conditions; four independent rev limiter choices from 6000 to 7500 rpm set the exact protection level needed; PC programmability allows you to define a wide-open and part-throttle curve, rev limits, dead-cranking revs and rear cylinder offset; A separate tach output wire allows clean tach operation during rev limiting and when in single-fire mode; A diagnostic LED indicator is included on the back of the control module to assist trouble shooting and static timing; Made in the U.S.A.; IMPORTANT: On any electronic advance ignition such as the Dyna 2000-HD1 or the stock Harley ignition, you must use carbon fiber-type suppression spark plug wires to reduce radio frequency interference. Use of copper wires may cause malfunction of the ignition due to severe electrical noise generated at the spark plugs. The original wire supplied by Harley-Davidson should be okay.; Not for fuel-injected models.; HDE systems are not compatible with Dyna “S” systems. Use HD1/HD2 systems only.
