Air Intake Temperature

Air Intake Temperature
I have recently been trying a Ecutek ECU Connect dongle which allows you to monitor almost everything the ECU monitors/controls
The most surprising thing (so far) is how long the air intake temperature takes to return to normal after the car has stood hot
I parked the car for 10 minutes with engine off, then drove off with AIT reading 45°C. It took a mile to come back down to normal (29, ambient was 22)
We all know not to give our Scooby's with TMIC's WOT off the lights for this reason, but I really was surprised by 1 mile

I think the dongle costs ~300. I thought it would be good to use as boost gauge if nothing else, but it 'adds' atmospheric pressure too, so mine shows 2.55 when really the car's boost is 1,55 bar.
Coolant temp is good to see, but predictable, and you can see torque too.
Can't see oil temperature, which if you could would clinch it for me

On the hatch - I have a front mount on the Type R so a non-issue

Not exactly a accurate reading what you want is something like I have in the for sale thread from PLX devices, AIT charge temps really need a probe plumed in for spot on readings , I would suspect your actual readings would be even higher if your getting those figures from a ECU or PSi3 without sensors added
Regards/ il bump the for sale thread to the top so you can see what it is

The parked up car after driving is the worst case scenario for a TM, it does do better with the engine running as the turbo pulls air through even at low rev's.

TMIC or FMIC
Still get stupidly high IAT if sat still for long,
More so if you have a cone filter in the bay,
Here's a log of my Blob Sti at strip with HDI FMIC & RCM Cone,
Que for around 15 mins creeping up to line stop/start traffic.
Water spray won't do jack in this case
You want a proper sealed off intake taking in ambient air from outside, anything less is just a compromise.

Still not below ambient temps by end of 1/4

Stock ECU has parameters for maf compensation based off IAT, Timing Compensation off IAT & Wastegate Duty,
So if mapped properly there should be no knock or hamr to engine if ragged when IAT are high,
The only downside would be reduced power if any of those compensations are utilised.

Surely though the temperature of the probe will always be higher than the transient air temp? The probe is static within the inlet, so will heat up over time. Whereas the air is passing through the same inlet at high speed and therefore won't be exposed to the temperatures for anywhere near as long?

Of course there will be a slight element of heat soak but the sensors will be as insulated as best they can be to stop this effecting things,
Plus if its erring on the slightly high side of things then your always safe
