    Weird IAT sensor problem

    Well did some logs today and came across a weird problem with my IAT readings. During cruising it worked just fine but when I got into boost it would go all wacky and say negative numbers sometimes and then say like 1* and soon as I get out of it, it would return to normal operation. I have a screw in sensor from RPS and it has been working great until now. Can the pressure be screwing with the readings? Thanks,

    Nick

    No The sensor is not right under the crossover, one of the legs of the sensor where it goes into the socket broke off. Like maybe the soldered joint broke. Just too much power lol. I really think it was defective. Put a new one in and its golden
