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.
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.
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.

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