See EasyTherm, EasyTherm/SensorTable for generic notes and tables.

It's very surprising that MAT stays very low all the time, only goes above 40C when the (hot) engine is stopped. It would be interesting to verify with an NTC if that is good. We'll see MAT above 200 HP.


please '''DO NOT FOLLOW THESE STEPS", as the EasyTherm "How to choose tables" method is MUCH simpler and faster, with the help of airXfactors.csv !

I used PTC_aref264_420 and got appr MAT=17C when real=24C

real Creal Freal internalMAT C|MAT F MAT internal ADC
24C 75 F 115=0x73 17C 63F 103=0x67 0x8A

The 0x8A value is the position in airXfactorptc_aref264_420.hex where 0x67 (MAT internal) lives.\n

To choose a calibration curve with 0x73 in the position where the airXfactorptc_aref264_420.hex has 0x67, I did this: grep 100280 airXfactorptc_aref2*'\n

As you see (sorry about the non-proportionate font, but the bold numbers are in same column),

0x72 or 0x73 is much better calibration. The theoretical value would be 256_430, but 260_425 or 256_440 turned out to be best match in reality. I think I will use 260_425
