Engine Sensors

Twin Cam 1999→ and Sportster 2004→ ignitions feature crankshaft sensors that count revolutions and indicate TDC.

Replacement for the engine temperature sensors installed in Twin Cam models.

While Evo ignition systems have only two ignition curves and switch between them with a vacuum switch, Harley uses maps and pressure sensors from the Twin Cam models onwards, which give a variable signal according to the pressure in the intake manifold.
