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.

where did you put all the sensors?
Oil temp? Water pressure? etc.

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!
