Crane HI-4TC ignition module for carbureted models and offers multi-spark performance, variable advance curves, and a digital rev limiter. It is a plug-in replacement of the stock module and is compatible with the factory security system. A crankshaft position sensor is employed to establish accurate firing. Rear cylinder timing can be offset from -5° to +4°; the same for initial timing. Both are easily adjusted by means of rotary switch on the unit. An additional rotary switch is used to select the advance curve, with choice of ten families. This enables the ignition to optimize the performace potential of the Twin-Cam 88
