Default Hydra IAT output voltage.

I already sent andrew@hydra this question, but it might be a few days before he gets back to me.

Does anybody know what the voltage output on the IAT sensor line is? It should be 5.0v correct? I have a new 2.5 box and the IAT is reading a constant -20c. I have ruled out the wiring/sensor itself. At this point I'm thinking I either have a bad signal line, or there is some setting I am missing or can't get to.

Also, does the hydra have an integrated 2.2Kohm resistor on that circuit? Or does it need to have one wired in?
