Hi Bud=2C
If I read you correctly=2C the 2000 would give me fuel flow with just one F
loscan ? I have a 912s.

It sounds like you need to look at your model as well as wire chasing
the EIS/flow scan hookups=2C as others have so expertly given you advise
for. There are different variations for the GRT EIS and differences in the
wiring.
EASY WAY: Send the unit to GRT and tell Sandy what you want.
She'll set up the unit and send the proper wiring diagrams to suit your
situation. The flow scan sensor itself is very trustworthy and I doubt it
is the problem. However if that is your only problem don't stop flying=2C
as
FF is a nice to have.
HARDER WAY.
Model 2000 is wired differently than Model 4000. The older 4000
models had to be modified for dual fuel flow. Model 2000 and early 4000
were set up for single fuel flow. So power up and find out what version
you have. The 2000 is ideal for the 912 but not the 914.
Get to know what version you have and study the manuals. The single
fuel flow is OK for the 912/912S=2C and the 914 needs to have the dual fuel
flow
EIS 4000 mod. Sandy at GRT can send you the wiring schematic/manuals if
that is all you need.
Attached is an .xlsx file which is my standard wiring hookup for GRT
EIS dual fuel flow on the Model 4000 for a 914 and it works.
Also attached is the model 2000 wiring hookup from a subie I did years ago
=2C
note it is significantly different. I haven't done a 2000 in 10
years (I get them converted) so I am a bit rusty=2C but I know that for und
er
$400 the Model 2000 can be upgraded to a 4000 the way you want it if you ne
ed
dual fuel flow or desire additional Aux inputs.
It sounds as if you were not supplied with the manuals from the panel
builder=2C so have Sandy email them to you. Hook up is a piece of cake=2C
just
follow the schematic.
When you call GRT=2C be sure to explain your particular setup and version
=2C
and they will give the the necessary recommendations and offer
recommendations=2C If you send the EIS to them=2C they'll have the techs se
t it
up for you. Then it is just plug and play=2C (after you do the setup
/ calibration procedures in the manual for proper reading of the fuel flow
=2C
of course).

Problems

I'm
still in the process of inital flight testing and now finding the
Flowscan
always reads 0.0 on my Grand Rapids EIS. All the connections
appear
correct (previous project builder). Just wondering if anyone
could
suggest a way forward.
I have checked the ground and thats OK and then
I checked the voltage
of the power source at the connector to the sensor
between the red and
black wires and this was 10.6 volts which is a surprise
as the power
cable is connected to the regulated 12 volt supply direct from
the
EIS.
This may or may not be the probem but I'm now in the dark
with solving
this puzzle.
Is there any way to check the output from
the Flowscan white sensor wire?
I would welcome any
suggestions. Regards
