I'm using the 36-1 trigger wheel, and can testify that it does work.

The sensor mounting is in relation to the trigger wheel.  Rotate the 
trigger wheel 23 degrees forces you to rotate the sensor the same 23.  
It works the other way to.  You can clock the trigger wheel relative to 
the crankshaft so that the sensor can be mounted in a more convenient 
place.  You can add a correction via the tuner software, but that can 
make things more complicated.

I've had several exchanges with the some of the people on the RX7 Club 
forums.

The MS is a fairly flexible piece of equipment.  If you could describe 
what your goals are and how you'd like to accomplish them, what pieces 
you've settled on so far, then I, and some people much more 
knowledgeable than I, could offer better advice.
