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,

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.
