Crane HI-4TC ignition module for TC-88 carbureted models offers multi-spark performance, variable advance curves, and a digital rev limiter. Module is a plug-in replacement of the stock module, works with 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 performance potentail of the Twin Cam 88 in any stage, from stock to wildly modified. Rotary switches also control the built in Sequential rev limiter, which is adjustable from 1,500 to 9,900 RPM, and won't cause "popping and banging" like conventional rev limiters. Benefits of multiple spark system include easier starting (hot or cold), better low speed driveability and off-idle response. It pulses up to nine sparks per cycle at idle and three sparks up to 6,000 RPM, which also stops spark plug fouling and lean-surge.
