About This Product
The Twin Tec TC88 ignition module provides an easy plug-in performance boost for 1999 through 2003 carbureted Twin Cam models, replacing OEM part 31655-99. Designed for Dyna, Softail, Sportster, and Touring bikes, this module features five top-mounted rotary switches for quick adjustments to timing and RPM limits. Because these engines use a non-adjustable crankshaft position sensor, the TC88 allows you to electronically set the initial timing and advance slope to suit anything from a stock motor to a high-compression build. It also features built-in diagnostics via the check engine LED, eliminating the need for expensive scan tools while offering optional PC connectivity for custom advance curves.
