I am currently using the RMI monitor with a Rotax 914. For the most
part
it works well, however I have not been totally happy with it.
Although I was told it was totally compatible with the Rotax 914 when I
bought it, I found out differently later. It is not compatible with the
Rotax oil pressure, oil temperature and CHT sensors. Oil pressure can be
used if you substitute their sensor for the Rotax one. However oil
temperature is a lot different, they want you to make a sensor out of
parts, and drill a hole in the engine to put the sensor in. They recommend
a ring thermocouple for CHT (the kind you put under a spark plug), which
seems to work okay, but Rotax does not reccomend it. I ended up with
separate mitchell guages for oil temp, oil pressure and CHT, using the
Rotax sensors. CHT is also monitored by the RMI using thermocouple, which
provides alarming for hi temps. This also provides monitoring of the most
critical engine parameters in case of failure of the RMI.
RPM works fine with the 914 using the RPM leads from the turbo
controller,
but I don't know how you would do this with the 912. I suspect that using
the method described in the RMI manual would not work.
I have also not been able to get their fuel flow monitor to work,
although
I bought the "two flow" kit to allow for the return flow.
Otherwise it is a fine instrument, with many functions. I have over 60
hours on it so far with no problems.
