what equation in excel do I use?

The first number is the resistance you should see at the second number PSI.

In my excel spreadsheet, I took it to the third polynomial cause I started with three good points and got this equation:

y = 0.0035x^2 + 1.4409x - 14.099

The first set was added later after bugging the DD engineers for two weeks.

Is this for the 0-400psi sensors? also do you have a config file for the 0-400psi sensor or does any one have the 0-400psi sensor working in their car?

Yes this is what I came up with for the 400PSI sensor and I am no expert so someone else needs to verify it with the four coordinates provided above.

As far as I know, I'm the only one.

so your work in the car? Your able to see the pressure your sitting at? I dont have the sensor yet, will be getting soon. just want to make sure it works.

Gizmo, does your sensor work in the car hooked up?
