How do you get the transfer function set up for this sensor?

Lund told me anything over 40psi was good on 93.

Any idea how that would translate for E85?

Awesome thanks!

This is what I’m using for a little cheaper and have it reading into my NGauge and HPTUNERS. lines right up with mechanical gauge on my regulator.

would i need the 12 to 5v step down if i'm using the omega boost box? I was under the impression that the omega can provide 5v to the sender...
does that sound right?

Not familiar with the boost box but a quick look seems like with the extra analog cable out it should be able to supply the 5v

Ok that’s what I was thinking... so on the sender there’s three pins obviously.. pretty self explanatory? Ground,+5v, and signal correct. Are they color coded?
Thanks for the help!

Yeah they would be color coded.

I know this is not a math forum... as fun as that sounds ... but would you mind me asking how you come up with the transfer function?

The sensor I bought had the data you see in the excel worksheet. Volts on x-axis and pressure on y-axis. Sensor is linear so y=mx +b but excel is nice and can give you the equation off the line that you see.
