This is a stock Mazda rotary engine mag pickup of some sort.
Might be a 3rd gen but I think it is an RX8 trigger.

5 ms per division so 25 ms  .025 seconds speed
RPM is 1/ms or 40 rev's per second or 2400 RPM.

5 volts per div so about +- 12 volts trigger pulse.
Pulse conditioning will be little more than a diode.
No amp needed.

You can see all I used is a simple bar of steel about
6 inches long 3/4 inch wide and 1/8th inch thick.
This is to trigger the 555 fuel injectors.
It can be rotated on the e-shaft pulley to set
the injector timing anywhere.

There is a movie and a picture.

Still working on the ignition triggers.
--------------------------------------

BTW at 1200 RPM it is still +- 5 volts
which is more than enough to trigger the 555.
