Creating Camshaft Signal

[turbo_bu]

Looking to build a circuit to create a cam signal using the crankshaft signal for doing some bench testing of an ECM. I made a crankshaft signal for my bench test rig using a 555 timer chip. Now I am wanting to take the crank signal and create a camshaft signal. It looks like using a synchronous counter chip should work. I did some internet research, but unfortunately did not find too many example circuits to do exactly what I wanted.


I am looking for any feedback about this design ... or if it will even work. I was also somewhat confused on which exact chip to use, so if I should use a better one, please let me know.
