Default 96 coolant sensor curve

I got really bored so I decided to measure the curve on a RockAuto OEM replacement for a 96 sensor.

RockAuto Sensor
Part # 9334

This sensor is shown for both the 96-97 and 94-95 on rockauto's site?? hmm
Here it is:

Take with a grain of salt. This was taken on a kitchen stove with a cheapo turkey thermometer.

These do seem to match pretty closely with the curve I am currently running ( one found on this site):

; Coolant -96 standalone
; File generated for use with stock 2490 ohm resistor at R7
; Steinhart-Hart coefficients: A= 1.219325E-03 B=2.78584E-04 C= 3.760558E-08
; Input Data: Temp, degF Resistance
; -4 16000
; 68 2450
; 140 580
