CLEAN DIGITAL SIGNAL FROM ANY SPARK COIL!The ZSF2 can “ring proof” the signal from any spark coil, providing clean 12V square waves from the spikiest magneto or longest-discharge C OP coil. With selectable “blanking” times from 520 microseconds to 4.3 milliseconds, it will even clean up “multi-fire” coil signals from aftermarket CDI boxes like the MSD 6/6AL. Smaller than a half dollar and double-sealed with urethane over epoxy, it's rugged enough to live beside the engine and tiny enough to hide anywhere. Four simple wires hook it up (power, ground, coil-in and digital-out) and 3 simple DIP switches select the re-trigger interval. The switches are changeable “on the fly” to make finding the right setting for your engine a snap. Jumpy tach signals have met their match! Show more
