Ignitions SystemsTWIN TEC IGNITION MODULEFOR 1999 THRU 2003CARBURATED TWIN CAMMODELSThe Twin Tec TC88 module offers easy plugininstallation.All the switches are accessiblefrom the top-a significant advantage for mostinstallations. Five rotary switches are used toset the operating modes, adjust the initialtiming and timing advance, and select theRPM limit. Since the TC88 engine uses a nonadjustablecrankshaft position sensor,mechanical timing adjustments are no longerpossible. The TC88 solves this problem witha switch for setting the initial timing.A secondswitch sets the slope of the advance curve.The combination of these two switches letsyou optimize the timing advance for a widerange of applications-from stock to highlymodified engines. An optional PC LinkInterface Cable lets you upload customadvance curves. The TC88 communicatesbasic diagnostic information by blinkingcodes on the check engine LED. Thiseliminates the need for an expensive scantool. For those that want a full upgrade oftheir ignition system we have a convenientkit available including module, coil, and plugwires.741990 Module, coil and wire kit for1999 thru 2003 carburetedTC88 models741988 Ignition module only for1999-2003 carbureted TC88models742001 Twin Tec PC USB Link interfacecableTWIN-TEC EFI TO CARBURETORCONVERSION IGNITIONThis ignition replaces the stock EFI moduleon all 2001 to 2011 Delphi Fuel Injected Twin-Cam models, except 2008 and later Touringmodels and 2011 Softails. It takes the stockconnector that used to go into your EFIcontroller when you are converting from FuelInjection to a carburetor.You just have to tapeup the connectors for the fuel injectors, IdleAir control motor, Intake Air temperature andThrottle Position Sensor.As with all carburetorequipped Twin Cam models the Manifold AirPressure (MAP) sensor must stay installedand connected. This ignition is fullyprogrammable for advance curve, RPM limitand so on,using the Twin Tec PC Link interfaceand the latest software. It does not get anyeasier!742033 Twin Tec Fuel Injection tocarburetor conversion moduleTWIN TEC IGNITION MODULEThis external plug-in ignition module offersease. Just remove the OEM ignition module,and replace it with the low profile billetaluminum Twin Tec module. This gives youfour rotary switches to select either SingleorDual Fire application, two advance curvefamilies with adjustable advance slope toaccommodate for stock to highly modifiedengines, adjust timing advance, and set theRPM limit in 100 RPM steps.Two diagnosticLED's indicate general status and the statusof the vacuum (VOES) switch.When used forstatic timing the status LED will flash whenthe engine reaches Top Dead Center (TDC).Works in Dual Fire mode with the stock 3Ohm coil.When you want to use the modulein Single Fire mode you have to ordermatching Single Fire coils separately.Ignition modules741968 With 7-pin Cannon style plug,fits 1990 thru 1994 EvolutionBig Twin models, and 1990 thru1993 Sportster models741969 With 8-pin Deutsch style plug,fits 1995 thru 1998 EvolutionBig Twin models, and 1994 thru1997 Sportster modelsOptional741972 High output, 3 Ohm, single firecoil05Electrical & Ignition05-023
