Details
MAT sensor (manifold air temperature sensor), also called as IAT sensor (intake air temperature sensor).
- Connector is included
- 14x1.5mm thread
- open design, fast operation, low heatsoak
- NTC type sensing element (Negative Temperature Coefficient means that resistance falls when temperature rises),
- appr 2252 Ohm at 25C (same or very close to the sensors used by automotive manufacturers, such as Bosch, GM, VAG).
- 2252 table (and aref=256) is a good starting point. Some use "2063" table with 1.0.x firmware, which gives a bit lower reading than real temp (so 101C reading is actually higher temp). This trick not needed, and therefore not a good idea in recent 1.1.x firmwares where the max reading is > 150 Celsius anyway.
