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.
I used PTC_aref264_420 and got appr MAT=17C when real=24C
| real C | real F | real internal | MAT 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,
- airXfactorptc_aref264_420.hex::10028000161E252D353D454E565F677079828B953C (0x67 is the 17C)
- airXfactorptc_aref260_425.hex::100280001F272F373F475059616A737C868F99A388
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
