Paul,
Here is the rough timing point for the 3rg gen rx7 injectors.
Notice the double signal from it's CAS.
It looks like right when the exhaust closes.

The p-port never closes. What does not make it into one face will make
it into the next face.  Intake timing is not critical.

Totally unlike a 4 stroke piston engine.

The rotary is the closest thing to a continuous combustion
engine just like a jet. Yes you get pressure waves in the intake and exhaust.

You can record them with a maximite.

Here are some samples.
