    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.

    Well RIXS10 did send me a PM ontopic, so not sure, but I'll respond here just incase:

    RFID is a low power transmission system. 100mm is really the range you should be getting. You can get larger range with much much larger systems. Think about the theft deterrence systems in walmart by the doors and things like that.

    The system you linked to outputs 12v. So you can use that as an input to the Fusion Brain if you send it through a voltage divider or you use the 4 channel isolator we sell (although you only need to use 1 channel for this).
