Here are a list of temp calibration files for different cars, files here are made for units with aref = 256 (standard since early 2006, see BuildProcedures/SectionThree)

Most installs best work with tempsensor_upload.bat 2252 2252 256

that is

Let's say

If you have doubts, provide measurement(s) so we can help you select the best temperature curve. Actually with the common ntc type sensor, just one temperature point is sufficient (easiest with cold engine when sensor temperature is same as environment)
