Time flies, but it has been updated
recently, maybe a year to 18 months? Would that be recent enough?

Depends on when your EM2 was last updated. If it was before i
started recommending the SW sender, it will have to be updated to work with the
SW sender. If later than that, there is a procedure for selecting the
type of sender in use in the calibration table of the EC2/3.
Tracy,
Will this sending unit calibrate the same as
the original unit you supplied with the EM-2? I tried to install another
VDO sending unit after I was told they leak because the one you had supplied
has never leaked. The damn thing immediately leaked!
I am trying to install one in front of the
fuel filter and one after the filter and in front of the pressure
regulator. This is so I can monitor the pressure drop across the fuel
filter so I may be able to tell when it needs to be replaced. I have a
switch in the line to switch between the two sending units but I think they
would need to calibrate the same???

Hi Joe,
For Fuel pressure use a Stewart
Warner 114875. These are available from
Summit Racing as PN SWW-114875.
There is only one sensor
you could possibly share with a monitor (inlet air temp) and I would not
recommend sharing that one.
All the best,
Tracy

Hi,
I am trying to put together an engine monitor to measure oil temp, oil
pressure, water temp, water pressure, fuel pressure, EGTs, tach,air pressure
(for delta P across the rad). I am using an EC4 to get the P Port running
and will switch to something else (EC-3) for flight. Sending units need
to be as close to working values as possible. The GM temp sensor looks
like it will work for water and oil and i got a program working using an
arduino board USBed to my PC. The VDO 360-009 0-80PSI looks like it would
work for oil pressure and the VDO 360-043 Looks like it would work for water
pressure. 0-30psi. What is every one using for fuel pressure? I
believe the target is 38 psi for the pumps that John used. I found an app
for apple devices that displays data and gets it via wifi. There is a
wifi sheild for the arduino so it looks doable. Thought it would work
while I dial in the P Port.
Can the engine monito and ECU share sensor inputs? Does there
need to be signal conditioning? Appreciate any help / input.
