I am currently wiring up an aftermarket ecu to my m52b28 and I am unsure how of the genuine bmw coolant temp sensor calibration (resistance v temp characteristics curve). Does anyone have any information they could provide me to assist? Thanks in advance
Part: 13621703993

I doubt there's such a diagram for your exact sensor. If I were you I would do my own measurements by boiling the sensor in water or oil while measuring it's resistance.
