The TC88 provides coverage for all 1999-2003 carbureted Twin Cam 88
® engines. The 50 states street legal TC88 EX version features advance curves suitable for all street applications including high compression engines. The TC88 Race version includes race advance curves with a slightly wider adjustment range. The TC88 is constructed with a low profile machined billet aluminum housing. The TC88 offers easy plug-in installation and all the switches are accessible from the top - a significant advantage for most installations.

Five rotary switches are used to set the operating modes, adjust the initial timing and timing advance, and select the RPM limit. Since the new Twin Cam 88® engine uses a non-adjustable crankshaft position sensor, mechanical timing adjustments are no longer possible. The TC88 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 highly modified engines. For details, including advance curves, you can download the installation instructions from our website.

H-D® motorcycles with the Twin Cam 88® engine have a check engine warning LED on the instrument cluster. The TC88 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 or low/high battery voltage.

An optional USB interface and Windows compatible software allow the use of a laptop PC to program a custom advance curve for precise dyno tuning and access additional features such as rear cylinder timing offset. The USB interface plugs into the existing H-D® diagnostic connector on the motorcycle wiring harness. The USB interface is sold separately, but Windows compatible software is available for download. The software will operate in demo mode without an ignition attached. 

TC88T - Special Race Version with Stage RPM Limiter for Drag Racing

The TC88T is a special race version with a stage RPM limiter suitable for drag racing. The input at pin 10 of the black connector normally connected to the bank angle sensor or TSM/TSSM module is used instead to select between the stage and maximum RPM limit. The stage RPM limit is set by means of the two rotary switches on the module. The maximum RPM limit is programmed by means of the optional USB interface and PC Link software. When the input on pin 10 is grounded by means of a switch, the stage RPM limit is selected, otherwise the maximum RPM limit is selected. For more details please read the TC88 Stage Limit Tech Note.
