Hi Joe,

Are you using the EM2?  If so, you can add VDO sensors similar to the
ones Tracy supplies. I get mine form eGuages.  http://www.egauges.com
There might need to be some machining done to mount them.  I think they
all use 1/8 NPT threads, not compatible with any hole on the Rotary
engine.  I tapped a hole in one of my AN fittings for the water temp
sensor.  Other instruments might vary on their requirements.

For the EGT sensors, the Micro-1000 probes seem to be a good value.
Since these are just type K thermocouples, they should work with any
system.

For RHT (Rotor Head Temp) I don't think the typical spark plug CHT
probe will fit in the recessed spark plug hole on the rotary.  My
rotors have a threaded blind hole near the spark plug that I believe
was made for a knock sensor.  That could be adapted for a temp
measurement but I wouldn't know what temps to expect there so haven't
tried to measure it.

The EM2 can be calibrated for use with just about any sensor.  I didn't
get an oil pressure sensor with my engine.  Do they use one, or just an
idiot light.  I did connect the oil level sensor in the pan to an LED
on the panel.  I sort of assume that if it ever comes on I will need to
replace the engine.  :-)
