Dash Logic and fuel pressure sensor set up
Hey gentleman,
I got my dash logic installed and working.
For those of you running fuel pressure sensors, how exactly do you install the sensor to the Dash logic.
The fuel pressure sensor has 3 wires (red blue and black-ground). Now my question is, where do the wires go, since the dash logic has only one input per sensor plus the ground input.
So do both the red and blue wire go into the AD1 slot on the dash logic?

Ok all wired up. Thanks for the help.
Now, big the question is, how in the world do I make it work.
I know I have to create a pid and enter a formula to convert the data into useable data in the dash logic configuration program. Thats where I am stuck.
I am using the aeroforce interceptor 150 psi fuel pressure sensor.
What formula do I have to enter in the dash logic configuration screen for it to work???
The aeroforce website doesn't really have anything on a formula, only that the slope that needs to be used is 37.5 and the intercept is -18.8

How would I enter that into the dash logic.
Reading the guide on dashlogics website, it says it should be in this format:
(pid(10001) * 40). Thats the example given.
So I guess it should look like this: ((pid(10001) * 37.5) - 18.8)
Those that look right?

For what it's worth, the slope and offset for that sensor should be 36.25 and -18.1. There was a printed instruction paper that came with my sensor that listed these values. Then I went onto Aeroforce's site, and it listed the ones you mentioned.
At first, I thought I was going crazy. So I emailed Aeroforce, and they told me to use the ones in the printed instructions. I politely mentioned that they should update their online PDF file to reflect this (maybe 4 months ago), but they still haven't done so.
Might want to try those values instead.

Hey street, I also noticed that late last night, the online formula is different than the one in the documentation received with the sensor. Mine actually is different than your figures as well, if I recall, mine called for 37.5 and -18.4. I will email them to see what they say, apparently they have changed the sensors a few times, as there are some 5 v and 12 v sensors out there.

Use whatever the printed instructions say. That being said, if it is readin 56/57 psi it is close. That is within the error of the sensor and factory FPR. Now setup a warrning so if FP <52 or something the car says something funny like "Yo dawg, fuel pressure dropping"

On my instruction set it shows: With resistor - 36.5 / -18.1
Without resistor: 36.25 / -18.1
I didn't use the resistor as they say it's only needed when used with the Aeroforce gauge. Mine is all wired up, but I haven't actually mounted my sensor yet. So I can't tell you what mine reads at idle. I wanted to mount it to my LS9 fuel rail, but found the sensor would hit the hood. Just need to order an inline fuel line adaptor. Maybe I should do that right now.
I'd like to hear what Aeroforce has to say, though. I know they had problems at one point with sensors failing, but I thought the resistor thing was supposed to fix that. Either way, it would be nice if they had the correct data on their site. Probably doesn't make a huge difference, but I want it to read as accurately as possible.

I'd just follow whatever your printed instructions say, and make sure you use the correct set of values. They include two different sets of numbers -- one to use with the resistor they include, and one for use without the resistor.

Unreal, thanks for that suggestion, I definitely will set up an alarm for that.
What other alarms do you have set up. I could only think of one other one I wanted at this time, coolant temp over 220. Im not too familiar with boosted cars, so not sure what other alarms would be beneficial to set up. Any suggestions are appreciated.

Knock retard >2 while TPS >80
IAT >150
AFR>11.5 while TPS >90
Boost > 30psi displays danger to manifold (just for fun)
FP<55 while TPS>100 (i run a rising rate so it is 50-51 at idle but should be 57+ whenever car is floored)
