Happy New Year Europaphiles.
I have used the EIS for 4 years also and have nothing but praise for the
unit although I have found the manual somewhat of a challenge.
I found the GRT EIS method of fault warning invaluable when I had a baffle
move in the exhaust silencer partially blocking the gas exit. The EIS
flashed a warning when this happened and we were able to diagnose a weak
mixture on full power causing a sudden rise in EGT. I would use as many
fault indicators as I could in future as it's so easy for the EIS to monitor
them and reliably tell you of faults as soon as they occur. EGT of course
being one of the most immediate indicators of problem.

Hi Mark,
I have been using an EIS 2004 for about 6 years now. I have had no problems.
Re EGT probes, although I fitted mine to the rear exhaust pipes, I never
refer to them and I am not sure if they contribute a lot. Perhaps useful to
troubleshoot a carburetor problem but I have never had that need. I think
you may do just fine without them and it saves some wiring.
I fitted the gasket type CHT probes under two rear cylinder head nuts. I am
not sure why the CHT probes were not supplied to you. GRT's website at
http://www.grtavionics.com/model_2004.htm says they are included. I
connected my EIS coolant temperature wire with a faston type connector to
the Rotax sender on the lower rear of cylinder no. 3. The oil temp sender
has a similar connector.
As I have mentioned before, I recommend GRT's excellent fuel flow and
totaliser option. I also have a low fuel pressure sender on the auxiliary
input - this is intended to give me few seconds warning before the engine
stops if the filter blocks or whatever.
Wishing you many smooth landings.
Cheers, John

Subject: Europa-List: Grand Rapids EIS 2004 (Rotax) Hi Folks, On the advice
of some of you on this forum, I went with the Grand Rapids EIS for the Rotax
912 as part of my panel upgrade.
A few questions though to those who have already fitted it.
1) Any problems I should look out for. Any gotchas?
2) It came with two EGT probes but nothing to say where they should be
fitted. I assume you drill a hole in the exhaust manifold but where. Is it
wise to drill holes in situ as swarf may end up in the exhaust valves. I've
gone all this time with no EGT indication so I'm inclined not to fit these.
What have others done?
3) It looks like you have to use GRT CHT probes (not supplied, Grrr). I
thought the GRT website said the unit used the Rotax senders or maybe that's
just oil temp and pressure senders?
Any help would be appreciated.
