This plug-in upgrade replaces the electronic advance ignition used on late-model Harleys, using microcomputer control for precise timing control. ⚙️
Riders can tailor the advance curve and rev limiter to their engine; four built-in advance curves cover stock to highly modified engines and four independent rev limiter settings from 6000 to 7500 rpm. 🔧
PC programmability lets you define wide-open and part-throttle curves, rev limits, dead-cranking revs and rear cylinder offset. 💻
A separate tach output wire allows clean tach operation during rev limiting and in single-fire mode. 📈
A diagnostic LED on the back assists troubleshooting and static timing. 🛠️
Made in the USA. 🇺🇸
Important: Use carbon-fiber suppression spark plug wires on any electronic advance ignition such as the Dyna 2000-HD1 or the stock Harley ignition; copper wires may cause radio-frequency interference and ignition malfunction. ⚠️
Not for fuel-injected models. HDE systems are not compatible with Dyna "S" systems; use HD1/HD2 systems only.
