Twin Cam engine utilize a non-adjustable crankshaft position sensor, this means that mechanical timing adjustments are no longer possible. The 1008/TC88 allows you to adjust your initial timing +-4 degree using a rotary switch. A second switch sets the advance curve slope. The combination of these two switches allows the user to optimize the timing advance for a wide range of applications – from stock to highly modified engines. For details, including advance curves, please download you can download the installation instructions from our website.

H-D® motorcycles with the Twin Cam engine have a check engine warning LED on the instrument cluster. The 1008 / TC88 Ignition Module communicates basic diagnostic information by blinking codes on the check engine LED. This eliminates the need for an expensive scan tool. Typical diagnostic codes include failed sensors and/or low/high battery voltage.

You can adjust the slope and advance curve total using the switches on the unit or connect using our TC88 PC Link software and USB adapter pn 18014 to optimize and build your own timing advance for a wide range of applications – stock to highly modified engines. For details, including advance curves, download the installation instructions (below). Note: USB interface 18014 plugs into the existing H-D diagnostic connector on the OEM motorcycle wiring harness.
