Don't know. You can
try this:
Set Ch. 13 Lower Limit =
0 (if this was set to 1 it may mean the unit was updated recently
enough, if 0, probably not.
Set Ch 12 (fuel press) to:
Scale Factor = 6.922
Zero Offset = 0
Sensor offset to current ADC reading on that screen (with no oil
pressure).

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.
