John -I switched to the "Charger Tube" which comes with the long sensor, a few years ago.
I can't data log, but I can see the two different temps on my EVIC. Depending on the outside air temp, they both can read within a few degrees of each other. With hotter ambient, on the road, temps usually with in 10-15. Hot and long idles, I've seen up to 30 for a few minutes.
Have no idea what the voltages are, just the EVIC readings, but the car seems to run fine or a little better than when it had the stock tube/goiter.
Those EVIC readings are:
- external air temp (not IAT)
- coolant temp (hidden EVIC screen)
- Oil temp (typically runs a few points above coolant @ slower driving speeds/stop & go).
The IAT sensor readings are accessed using a tuner or ODB-II scanning tool.
