# Thread: Tutorial - Air Ride Suspension

1. I might sound stupid now, but what is "the FB" ??

2. the fusion brain, the hardware that lets you control the air ride.

For my setup I cant use the 0-150psi pressure sender. will this sender still work? The code on the first page, will that work for the 0-400psi pressure sender unit?

0 - 400 psi, Universal Pressure Sender / 1/8
The code is for the 150psi unit. If you use something else than you will need to calibrate it, or find a pre-done curve. If you find a predone curve, then you can plug it into Excel and get an equation easily.

and where can i get this fusion brain ?

and where can i get this fusion brain ?
Both at our store (in my sig) and in the mp3car store (top banner).

how do I calibrate it? is there a pre-done curve? how did you get the code for the 150psi one?

7. anyone have info on this?

You calibrate it by reading in values and comparing it to known values. So put the system at X psi, read in the value, and therefore that value = that psi. Change system to psi Y, then read in the value, and therefore that value = Y psi.

You have to look at the sensor datasheet to see if they already have a curve. More than likely one exists somewhere, probably in psi vs. resistance.

We got the code for the 150psi by doing exactly as I described above.

Good luck with that. Here's what I got.

This is what the engineers at Dakota Digital were able to find for me:

Resistance PSI

20 16
75 114
100 164
150 280

Someone probably needs to call them again and see if they ever found more data.

I see most people with gauges in their cars(Chrysler 300) run like 90-98 psi int the front 100-106 psi in the rear with the 400psi sensors. I only can use this sensor, so are the numbers above all psi or resistance?
