Some interesting data Dave
At the risk of boring, below is a post from another recent thread highlighting the thermistor’s inaccuracy within my Ford air intake sensor. It was reporting circa 40% high at 9C ambient, consequently I suspect my ECU is being fooled and my car will be running sub optimally with respect to the ambient air entering the engine
Time to get my
adjustable TMAP out and fitted
It’s good fun to check the quality/cal of the intake temp sensor at rest. Mine is way off. Below is what my ECU was recording at lunchtime today compared to a thermocouple stuffed in the intake (with the car sat in a cold garage, with only the ignition on and hasn’t been started for a few days).
9C and 13C.
