IAT resistance curve

Does anyone have the resistance curve for a series 4 turbo intake air temp sensor?
A picture would be nice, but if you even have three points (one cold extreme, one midway, and one hot) that would work too.

A "chart" is posted in the Mazda FSM.

Oops, scratch that...

32F -> 110.9k ohms
50F -> 66.6k ohms
68F -> 41.4k ohms
86F -> 26.5k ohms
104F -> 17.5k ohms
122F -> 11.8k ohms
140F -> 8.2k ohms
158F -> 5.8k ohms
176F -> 4.2k ohms
(All resistance ranges are + or - 10% of spec resistance.)

My friend and I actually swapped a Corrado G60 (supercharged 1.8L) into his 84 Rabbit GTI, and we're running a Megasquirt ECU.
We're also using an RX-7 Turbo air intake temp sensor, so that's why I needed the curve.
