those are probably variable reluctance sensors those are not trivial to simulate.

The Jimstim can "emulate" something similar to a VR output- it simply runs a square-wave signal through a capacitor which creates a 0-crossing similar to what a VR output looks like. It's crude, but MAY work for you. No idea if your specific trigger configuration is included.
