Product Description
Plug-In Ignition for Sportster® Models with Single 12 Pin Connector for Harley Sportster


2003 and later H-D® carbureted models using the new 12 pin ignition module. Fits 2004-2006 Sportster® engines and includes race advance curves with a slightly wider adjustment range. It is constructed with a low profile machined billet aluminum housing. The unit offers easy plug-in installation and all the switches are accessible from the top - a significant advantage for most installations.

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. It 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.

New H-D® motorcycles use the SAE J1850 data bus for communications between the ignition module, instrument cluster, turn signal/security module (TSM/TSSM), and diagnostic scan tools. It fully supports this new J1850 data bus including the use of the H-D® scan tool to read sensor data and clear diagnostic codes.

The module features built-in data logging that stores data for the last 30 minutes of engine operation including RPM, vehicle speed, manifold pressure, ignition advance, and battery voltage. Engine builders will find the data logging feature highly useful for tuning, diagnosing problems, and reducing unjustified warranty claims.

An optional USB interface (P/N USB-INTF) and Windows compatible software allow the use of a laptop PC to program a custom advance curve for precise dyno tuning, download data logged by the unit, and access additional features such as speedometer/odometer recalibration (to accommodate tire and gear changes). 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.

Like the H-D® OE module, the Twin-Tec sends RPM data to the OE tachometer over the J1850 data bus. TC88A units with firmware revision 2.0 and higher also provide an optional 12 volt square wave tach signal (one pulse per revolution) This allows you to retrofit a wide range of tachometers to newer 2004-2006 models. Please download the installation instructions for details on tach hookup. If you plan to use the optional tach hookup, you will require the PC link cable and software to enable the tach output
