CLT

Stock Audi

Audi Part Number 035 919 369

Bosch Part Number 0280 130 037

0 Celsius >>> 5,68 Ohm

100 Celsius >>> 0,363 Ohm

15 Celsius >>> 2,82 Ohm

With default (?) firmware now with AREF=256 reading 7 deg more then real at temp...


MAT

Stock VAG Bosch with MAP sensor

Bosch Part Number 0281 002 401

Audi Part Nuumber 038 906 0516

0 Celsius >>> 5,93 Ohm

100 Celsius >>> 0,343 Ohm

15 Celsius >>> 3,05 Ohm

With default (?) firmware, now reading 7 deg more then real at temp...

,for this clt and iat config.

If I understand right (on phone), you've found and successfully tried ( from EasyTherm, hexpatch.exe vems.hex ... of 1.0.36 firmware ) best characteristic curve for your sensor and ECU.

Publish any measurements and best-so far curves.


MAT calibration

I used hexpathc.exe from EasyTherm, it worked fine, then i uploaded the new firmware,and TADA,the IAT now reads only 2deg less then real.I used airden_3000_287

AREF is a resistor (bottom of BuildProcedures/SectionThree) that effects a few readings like battery, MAP, nernstdc and CLT/MAT temperatures (=> different calibration)
