Custom reluctor ring, suggestions on where to get one

About $5 will buy an arduino nano, it can generate the simulated crank and cam sensors. The evaluation version of CVAVR compiler is free. An eight channel logic analyzer made in China about $15 might work with sigrok.org software. Or buy real Saleae Logic $150 nicely made with better software and support.

I have provided example software for generating sensor signals on my post about COP ignition project.
