dashlogic for fuel PSI
I have a fuel pressure sensor connected to my fuel rail and wired into my dashlogic analog channel 1. The only thing I can get it to read is the voltage of the sensor. I've tried typing in the formula to convert the voltage signal to PSI , but I cannot get it to work.
if I use the ( ) as shown in other posts on this forum, it just shows exactly what i hav entered. if I use the { } it just shows the voltage signal from the sensor.
I'm trying to get it to convert the voltage to PSI by adding the following formula to the signal voltage *36.25 = 18.1
* the 2.16 below is an average figure
Fuel PSI = {10001} - shows "Fuel PSI = 2.16"
Fuel PSI = ((pid(10001) * 36.25) - 18.1) - shows "Fuel PSI = ((pid(10001) * 36.25) - 18.1) "
I've tried several other combinations and cannot get it to display correctly . Some of the formulas I enter just show "Fuel PSI = N/A"
who here has gotten it to work?
for reference, it's a 150 psi sensor
.5v = 0
2.5v = 75psi
4.5v = 150
the 5v supply is tapped off my MAP sensor, the signal and ground are connected to the dashlogic analog input.
I've got to be missing something simple!
