The Dyna 2000i Programmable Ignition is the newest addition to the successful line of Dyna 2000 ignition systems. The 2000i not only adds to, but extends many features of the best selling Dyna 2000 module out of sight in a completely new design that fits under the cam cover. All 2000i ignition modules are PC programmable, putting you in control of your Harley’s performance.

Featuring single fire operation down to 0 RPM for easier cranking and kicking, the Dyna 2000i will operate in all combinations of single fire or dual fire with single plug or dual plug heads (when used with appropriate coils).

The Dyna 2000i’s built in tach driver delivers stable tach signal, even during rev limiting or can be used to activate shift lights, auto shifters, and other accessories.

This module features data recording, keeping track of total engine hours, time at wide open throttle, number of engine starts (2 minutes running counts as one), longest time operating at wide open throttle, maximum RPM, seconds near rev limit and statistical analysis of time at RPM.

Every time power to the ignition is switched on, the 2000i will check to see if the coil is shorted, mis-wired, or the wrong type. If an error is detected, the 2000i will immediately switch off and issue a warning by rapidly flashing the status indicator. Besides protecting the unit, this also prevents the costly failure of an improperly matched coil going bad one hour into your ride. After starting, the 2000i continuously monitors the coil and wiring status.

With active dwell control, the module continually adjusts coil current to maintain maximum spark energy all the way to redline while eliminating coil stress caused by overcharging at idle. High efficiency design reduces battery draw for easier cold weather starting and lower charging system load.

The Dyna 2000i was built to last — it cannot be damaged by broken or disconnected spark plug wires. The harness was constructed with TXL cross linked polyethylene automotive wire for exceptional resistance to abrasion, heat, and chemical attack. High temp glass braid jacket further increases the toughness of the harness and provides a tight, clean appearance. Wire colors closely match the factory harness for error free installation.
