I think the simple solution to the trigger problem is to
start cranking the engine (or running off the other rotor)
and then manually trigger a single sweep (remember we have a
storage scope here).  A sweep time of about 250mS should
give you 6 pressure spikes (two full turns @ 500 rpm).  After you have
taken a few samples make a big impressive printout of everything,
hang it on the wall and figure out what it all means.  I suspect all
you will know is if you have six spikes that look the same is to
be happy anything else go get your wrenches out....  I think you
might want to run a regular compression test as well so you
know what the max pressure it in real terms. (the pc scope will
not be very well calibrated in the Y axis)
