TC88A Plug-in Ignition (for 2004-2006 carbureted Twin-Cam 88® and Sportster® with new 12 pin ignition)
A single TC88A part number provides coverage for all 2004 and later H-D® carbureted models using the new 12 pin ignition module. Four rotary switches are used to set the advance characteristics and RPM limit. Since the new engines use a non-adjustable crankshaft position sensor, mechanical timing adjustments are no longer possible. The TC88A solves this problem with a switch for setting the initial timing. A second switch sets the slope of the advance curve. The combination of these two switches allows the user to optimize the timing advance for a wide range of applications - from stock to high modified engines.
Wide timing advance adjustment range accommodates stock to highly modified engines
Digitally set RPM limit (100 RPM steps)
