Stock your Camaro has a MAF sensor which has a IAT (Inlet Air Temp) sensor that is buried inside the MAF sensor. In my opinion and based on my testing this MAF/IAT can easily become heat soaked, especially if you drive your car then park it for a while. Once the sensor is heat soaked it can take it a fair amount of time to recover... During this time when the sensor is heat soaked the IAT sensor will report an air temp that is actually much higher than the actual air temp.

When the car's computer sees this high air temp it will start pulling timing which reduces the cars performance... people have reported noticeable performance difference when this happens... Also this heat soak problem is common in a lot of other vehicles have a single MAF/IAT sensor... and a lot of those owners do the same thing... buy a separate IAT sensor and use that one instead of the stock one....

hope this helps...

Hey screaming, i wish i lived near you, i would pay you to do the IAT sensor trick since i dont have the knwledge nor the dodgeballs to do it myself lol

Well... if you ever get to the Detroit area... let me know!

jeffny09 · 11-23-2009, 07:50 PM

ooo i got ya
makes sense

so what are you doing to stop that? yo have to take maf apart?

ummm... actually that's what this whole thread is about... installing a separate IAT sensor...

You install the stand alone sensor and wire it in place of the stock one...

ahh..I was in the middle of responding to this and scrming....you just beat me lol.

Jeffny09...go back to original post and re-read.

jeffny09 · 11-23-2009, 08:15 PM

gotcha
i dont think im able to do this mod - not electrical friendly

i just ordered the airaid, and IAT trick today along with the dashhawk. All of the info scrming has posted and documented convinced me to go for it. Even though electrical is my achilles heel, he made it look simple enough for me to "pull the plug"..haha

I've been hinting all week about our IAT sensor and heat soak... Well, last Wednesday I make a trip down to MRT for a little help with my Air Intake Experiment - Part I.

So what is Part I? Part I is adding a stand alone IAT sensor and locating it in a spot that won't be so exposed to engine heat like the stock MAF/IAT sensor is.

So what's involved? Buying a IAT sensor and correct pig tail. Determine which two wires out of the five wires that go to the stock MAF/IAT sensor that are for the stock IAT. Cutting those wires and connecting the new pig tail. And finally, drilling and installing the new IAT sensor! Some quick snapshots:

Getting the wiring right!

New sensor in the air box lid:

Shop was 65 degrees but the stock IAT still read 97 degrees even though the car had been sitting for quite a while:

And new sensor is reading the air in the engine bay as 72 degrees.. which is more realistic... since the hood had been up for quite some time!

Everything all together!

So now your are asking... did it actually make a difference? Hmmmm... I'll let you decided... I took the car to the drag strip today... My best run has been 14.69 @ 94 MPH... Best 60' is 2.14...

Here is the slip from today... Left Lane - Car 260:

The air was in fact a bit better today than usual... but most importantly my IAT temps today were only 5 degrees above the outside air temp!! Typically the IAT temps are 15 to 20 degrees above the outside temp by the time I get the car staged! Looking at the data logs it looks like the car is running about 5 degrees more timing.... Needless to say i was geeked! LOL!

So stock you were putting down 239 hp at 94 mph in the 1/4 and now you are making 262 hp to go 97 - I guess moving the AIT sensor can do a little bit but 23hp - I would have to see that 1st hand - I am happy you picked up all the power - I just can't believe it all comes from move the AIT alone - in any case congrats

No worries. Just buy a plug-N-play unit like this: VECTOR HSRK

Better air definitely helped too...

BUT..

The thing is by the time I was through the staging lanes and then staged at the tree the stock MAF/IAT would start showing signs of Heat Soak... especially if the car had been parked in the pits! My IAT would be reading well over 100 degrees! So my 14.6 was not at full power due to the heat soak and the ECU pulling a bunch of timing!

So now when I'm at the tree, the IAT is no longer heat soaked and the ECU isn't pulling all that timing! The heat soaked stock IAT was robbing me of 4 to 6 degrees of timing! (I have the data logs somewhere... LOL)
