Intercooler effects on IAT testing video

Here's a video showing some IAT temps during a 90*+ day. Just driving around town.

Re: Intercooler effects on IAT testing video

That's good video, but it would be better if you explain what is each one of the values on the computer screen. It wasn't very clear to me which one is EOT, ECT. etc. Plus, what kind of set up do you have? CAI? stock oil cooler? etc.
Thanks

Re: Intercooler effects on IAT testing video

OAT wasn't a PID that I was able to find in the AE menu. For the record the EATC inside the truck showed OAT was between 90-95*F thru my driving. I'm comfortable saying the temps were in the 90's for the testing.

Settings Left to Right; Top row to Bottom row:
Baro// IAT1// IAT2
Vehicle Speed// MAF// Manifold Pressure (boost)
ECT// EOT// EBP

Remember the OAT was over 90*. I wanted to demonstrate the daily driving/stop-n-go one might most commonly encounter. I need to get a larger capacity SD card to show the temps during HWY driving.

--This is one of the few times I have used AE. Some of the readings are/were expected while others gave me some things to research. While AE gives a TON of PIDs to monitor these were the ones I felt were suited for the demonstration.

--The Baro seemed to change while driving which I didn't expect to see. It might be a result of using the AE.

--EBP is reading absolute so you need to subtract at least 14.5 PSI from the reading to show actual EBP.

--IAT2 was higher than I expected to see. I do have some theories as to why that temperature seems so high compared to IAT1 and OAT. The temp did seemed to settle in after a bit of driving at over 165*F.

My thoughts:
A) Possibly the IC interior and exterior need to be cleaned. I ran the CCV for awhile before doing the CCV delete. I can easily pressure wash/degrease the exterior but the internal cleaning will have to come later.
B) Running the billet single plane compressor wheel may cause the IAT to rise due to the increase flow and compression of air.
C) Radiator and IC proximity to one another causing radiant heat transfer. Maybe but I'd say unlikely considering the IC is in front of the radiator. Another Idea: This radiant heat transfer may play a bigger part when the truck isn't moving. So the radiator radiant heat could be causing the aluminum IC to be heat soaked and not as effective.

An interesting note: Towards the end I was thinking about the IAT temp. I happen to have an handheld IR thermostat so I wanted to check the intake manifold surface temps. As expected the areas closest to the intake elbow were close to the readings off the AE. I began to wonder if the IAT2 sensor was getting heat soaked from the GOGO manifold covers.

--Link below for the Sentry ST660. +/-3*F for the range I was using.

So unless you take the time to find YOUR real world information before and after you cannot say what has changed.
