Thanks Mark, doesn't the temperature probe tend to
block the oil flow through the 'cool fitting'?

question
Bill,
I drilled an extra
hole in the oil filter adapter for an extra pressure sensor. Using this
cool fitting (see attachment), I added a port to the front cover oil outlet
for a temp sensor to enable me to measure the delta T through the oil cooler
(temporary arrangement). For coolant, I drilled an extra port in the
thermostat housing for the extra coolant temp sensor. I chose not to add
a second coolant pressure sensor. The fuel pressure regulator had an
unused port that I used (with an adapter) for the extra fuel pressure sender,
but I could have just as easily used a tee.

Oil temp? Water pressure?

question
Bill,
I should have
consulted with Tracy before I went down this road
myself. Anyway, I just installed redundant senders for oil, coolant,
and fuel. Temp sensors are very lightweight. Pressure sensors
are just a tad heavier. I didn't get the extra data board on my EFIS,
so EGT's & CHT's are on the EM-2 only. Since the weight penalty of
the EFIS-1 has already been paid, I figured why not go with engine
instrument redundancy. The only one I'm not satisfied with is the
engine RPM on the EFIS-1. It doesn't agree with the RPM readout on the
EM-2. Until proven otherwise, I'm assuming the EM-2 figure is
correct. Once I get the prop installed and can run it without fear of
overspeed, I can put a prop tach on it and know for sure. Then I can
calibrate the EFIS-1 RPM's. Be sure to calibrate all sensors!
