Temp Probe Question

[sneitzel]

I just installed white gauge faces on my Z28. Easy install, and replacing the needles was not as difficult as I thought it would be but I have a little question about the accuracy of my temp readings now.

I'm assuming that the temp. sending unit is just a standard type of thermocouple meaning that X resistance = Y Temperature. Is this correct? If so, does anyone have a chart showing what resistance = what temperature? I have a multimeter (and I sort of know how to use it...) and I'd like to verify and adjust my temp gauge if necessary.

I also see on shoeobx's website there is a separate sending unit for the PCM and the gauge. Are they both the same?

Comments?

I don't have that info handy, but if you had a scanner you could read the data stream and you can see exactly what the computer sees.

I should have kept reading before I posted......The info I requested is also on Shoebox's website. http://shbox.com/1/4th_gen_tech2.html#ect

Its not a thermocouple, its a thermistor. The table is also in my scanner writeup:
