I would like to build a circuit that will produce a square wave emulating a crank sensor signal. I know how to build a circuit to produce a square wave with a 555 timer and use a variable resistor to change the frequency. The problem is most engine controllers look for and extra wide tooth on the wheel, like a 60 -2 wheel. How do I produce a pulse with 1/2 the frequency every 58 oscillations???
Thanks,
