Im trying to add a generic oil pressure transducer to neptune rtp. Im just not sure if im doing it correctly. I wired it up as per instructions on sensor and using d12 egr lift as signal input. On neptune i went to input settings and changed name of egr lift to oil pressure and added the voltages .5v for 0 psi, 2.5v for 50 psi, 4.5v for 100 psi. I see come up on datalog as oil pressure but it constantly reads 100psi. Am i doing this right? What is inputs2 tab for? Inputs2 tab under analog1 has no drop down to select the input source so that didnt make sense.

 

I know this is an old thread but have you solved it yet? I am trying to do the same thing and I want to use it with tuner view.

 

Where are you pulling reference voltage from?

 

D12 egr

 

No that’s an input.

A pressure sensor has three wires. One signal, one reference voltage, and one signal ground. How have you wired up this sensor?

btw don’t use VCC1 for your reference voltage. That needs to stay dedicated to your map sensor. Everything else goes on VCC2.

 

Now I get it. I have the one wire oil pressure sensor. So first i have to buy a 3 wires pressure sensor and wire the reference voltage to vcc2 ,the signal to d12 and wire is ground. After that i have to configure it in neptune right?

 

Yep, that’s the way. 👍🏻

 

Thank a lot bro. I appreciate it.
