I have a
AEM Digital Display Gauge
Fuel Pressure, 0-100 psi, Digital, Electric
It has a serial and a 0-5 volt analog output.
I would like to create a pid for the 0-5 volt analog output.
and, alas... don't know where to start.
Thanks....
Ed

What is the part number of the sensor?
You need to know what the voltage output to pressure is.
AEM lists 2 100psi sensors.
AEM PRESSURE SENSORS (http://www.aempower.com/images/products/Installation%20Instructions%20Pressure%20Sensor.pd f)

If it is 30-2130-100,
then it looks like it is the same as the one used here
LS1 Fuel Pressure Sending Unit Tutorial (http://download.efilive.com/Tutorials/PDF/LS1%20Fuel%20Pressure%20Sending%20Unit%20Tutorial. pdf)
In which the PID will be

*CLC-00-001
PSI 0.00 100.00 0.2 "({EXT.AD2}*25)-12.5"
#------------------------- ---- ------------ ---------------- ----------------
CALC.FP F001 CLC-00-001 PSI Fueling "Fuel Pressure"

Oops... I replied before reading your entire reply...
Yes, that is it.
I should have looked there, but never gave it a thought.
Thanks!!!!!!!

Add this to the top.
*UNITS
#Code System Abbr Description
#-------- ---------- -------- -------------------------------------------------------------
PSI Imperial PSI "Pounds Per Square Inch"

Or use this
4797

OK THANKS!, that worked...
on another note.
I had another calculated pid on that page, which I just removed.
To put it back, would I just change
F001 CLC-00-001
to
F002 CLC-00-002 on the other one???

That`s what I do.
The FP was my first one and I am up to 23 now.

--never mind, I got it.
Just had to do a bit more searching...
I had the format wrong.
Thanks again!
