STABLE TACH SIGNAL FROM ANY COIL!

PROBLEM:  Magnetos may fire when nothing else will, but getting a usable tach signal off a kill-wire is an exercise in futility.

NOT ANY MORE:  The ZSF2 works with Vertex, aviation and marine mags, and small-engine mags of all sorts.

PROBLEM:  You can't tap coil signal on a multi-fire CDI box like the MSD 6/6AL.  If there's no digital output or the output quits working, you're sunk.

NOT ANY MORE:  Programmable timing settings from 500 microseconds to 4 milliseconds make any number of "multi-fire" discharges look like a single pulse.

PROBLEM:  Some DIS packs and 2-wire COP's "ring" so badly at low speed that the tach reads wrong at idle.  Guess I'm stuck with it.

NOT ANY MORE:  With timing settings out to 4 milliseconds per discharge, even the slowest-firing COP's can't confuse the ZSF2.

This tiny but mighty device can solve all those problems.  It's the size of a quarter and needs only 4 connections (power, ground, signal-in and signal-out) using .110" fastons from any parts store.  The connections are color-coded for easy hookup and settings can be changed "on the fly" to make finding the right timing for your ignition a snap.  It's double-sealed with vinyl over epoxy, so it's IP66 if you RTV the DIP switches after setup.  It's also vibration-proof and withstands temperatures to 225F, so it's perfectly comfortable living in your engine box.  It comes with a 90-day warranty plus free email tech support if you need it.
