Different types of IAT sensor + Calibration
Is anyone using any different sorts of Intake Air Temp sensors?
If so, please post your outcomes.
My research shows that this GM sensor came off a late 80's Pontiac, (which we have bugger all of, over here in NZ).
I am thinking of trying a japanese AIT, mostly because the cost is way less, but also because they are more available.
I realize you would then you would run into calibration difficulties, which would be my next question: How did you calibrate it to MS?

You'd have to determine the sensors resistance at different temps to development the curve. Then you plug in those values into EasyTherm. Then burn them into the firmware.
put sensor in ice cold water, verify temp with accurate thermometer, measure resistance.
put sensor in warm water, verify temp with accurate thermometer, measure resistance.
put sensor in hot water, verify temp with accurate thermometer, measure resistance.
those temps and those resistance values get plugged into EasyTherm.
btw, this is documented in the MS section.

The AEM sensor also has a plastic tip vs. GM sensor's metal tip ... AEM costs more but it's threaded: AEM - Air Inlet Temperature Sensor Kit
