CHT Locctions, It works, but.... Options

[jd66921]

I just installed a VDO CHT kit. I could not get the sensor under the #3
spark plug as recommended, so I temporarily placed it under the CHT
for the fuel injection system. I used a large washer between the original sensor
and the new one, so the new sensor is in direct contact with the head near #3
cylinder.

Has anyone ever experimented with locations? So far, I am happy with it
where it is. The gauge is responsive and "interesting" to watch! The response
time is quite fast. At idle the temperature goes up, and drops as the engine
speed increases. This is pretty much expected, but more than I would have
expected.

My only concern is that the absolute temperature is quite low. Driving at ~40,
the gauge reads about 175 degrees. At idle, it goes up to about 225. At speed
it seems to be about 200. I expect my location is not optimal, but I mainly wanted
to see the trends. Even if is is low by 150 degrees, I am about right, based on
information from lapuwali (boy, I miss James already (IMG:style_emoticons/default/sad.gif) ).

Does anyone have any input on my situation? This is an underpowered 1.8 L-Jet.

Thanks,

Jeff
