N Gauge readings

[Goosey]

I posted this in the wider "global" section as I imagine a few more will have a view on this given the nature of the question, however thought I would raise it on the knowledgeable UK section
I was checking what the Ngauge called INTAKE air temp and it was registering say 10 degrees c however the gauge in the car was saying INLET AIR TEMP of 20 degrees c the N gauge was always about 10 degrees below the dash reading. Are these measurements of INTAKE and INLET the same thing, if so why would a ngauge plugged in and reading the vehicle data showing such a variation? It seems accurate with other readings. MY reason for checking is I fitted a PMAS CAI which seems less well insulated from engine temperature....apart from looking pug ugly ! Does anyone else notice a variance in the two?

Ones not Fahrenheit and the other Celsius per chance?

THats is a great call, but yes I did check they were both centigrade, I did have to re scan the car to change the n gauge to metric but they are both showing the same units

Interesting, I was wondering if it was a genuine fault....I am doing a data log over the weekend and have asked Jon Lund the question re the 2 IAT readings, He has suggested he will have a look at the log and see if he can answer the question.

Hopefully get an answer from you more knowledgable guys. I have purchased a Dreamscience tuner with Tune and wondered if a Lund tune could be loaded onto it to save me having to buy a Lund Gauge. Cheers in advance for any ideas !!

When I borrowed Mac's nGauge the IAT on it matched the one on my dash, not much help I know.
