I constantly monitor my ECU... I have had ZERO issues... my fuel trims look good, my timing looks great and spark retard is fine. And there are lot of other guys out there that have done the same thing on their other GM products.... again, don't seem to find anyone complaining...

Hello scrming,

Again, AIRAID does not recommend this mod. It does “Trick” the computer to read a cooler air temp, which can change the timing and cause harm to the vehicle.

I am glad that “YOU” have had Zero issues, however we do not recommend it at all.

If you would like, PM me your # and I can have one of our engineers contact you and explain to you how this works, and why we do not recommend it.

Thanks,
David

You don't recommend it for legal reason, i completely understand that...

The issue is the fact that the stock MAF/IAT is prone to "heat soak". This is not an issue with the Airaid CAI. It is an issue with the stock MAF/IAT sensor.

Let me try explaining it this way. Go out and drive your car until it's good and hot... Now park it for say 15 or 20 minutes. During that time the MAF/IAT sensor becomes "heat soaked".

Watch the video showing this:



The IAT temp spikes to 122 degrees. When the car starts and revs a bit it does drop down to 100 to 102 degrees... better but still well above the 82 degrees it started at. It takes about 3 miles of highway speed driving to bring that temp down in the 80s. In stop and go traffic it never recovers... the problem is the IAT sensor is buried inside the MAF housing and at this point really isn't accurately reading the actual air temp... so in this case the stock IAT is "tricking" the computer into thinking the air is HOTTER than it is.

More from the story... After doing this video we pulled the car into the shop, opened the hood and removed the stock air box lid to install the new IAT sensor. Not sure exactly how long we took but we didn't rush it... Maybe 10 or 15 minutes? So during this time, the stock MAF/IAT sensor was out of the car sitting on the work bench, exposed to the shop air!

Now here's the thing. We put the air box lid back on and before we taped up the wires I took a few pictures to document things....

1) The temp in the shop was 65 degrees. Car has been in the shop hood open and the MAF sensor has been out of the car most of the time:




2) Hook the stock IAT sensor up. The stock IAT sensor is reading 97 degrees:




4) Switch over to the new IAT sensor. Sensor is reading the air temp as 72 degrees.




Remember the hood has been open 20 minutes at least... the air box has been open... the MAF sensor out of the car... which temp do you think more accurately reflects the air temp?

Again, the issue is not with the Airaid or it's design. The issue is with the stock MAF/IAT sensor. Once the stock MAF/IAT sensor get's hot, the internal IAT appears to read the residual heat coming off the sensor itself as opposed to reading the actually temp of the air going by... so by your definition it's "tricking" the computer into thinking the air is hotter than it is!

I know this works for me... I'll do the disclaimer... do at your own risk... your mileage may vary... but if I'm so far off base why are so many others doing this and and why do companies sell complete relocation kits?

im not picking up this density thing, is colder air not more dense then hot air...? so would it not be benificial to have denser air

Yes, colder is is more dense... dense air is better... Check out Drag Times DA calculator... you can see how things like temp, barometer, and humidity effect things...

Given that fact of cooler air density (basically the reason for a CAI system - mass airflow and in the Airaid system, through a venturi that increases the flow rate) and that the Airaid system does in fact appear to provide a cooler read for the temp sensor, why would'nt a car with an Airaid system at a higher altitude be more likley to run like a car at sea level as mentioned prior in the thread.

You cannot make up 7000 feet of elevation with just a few degrees... again play with the DA calculator:

Hello- I am new to the mod game so bear with me. First, it seems that a cai will bring out more torque and horsepower in most vehicles. So why do we not see these come standard in more cars? Second how much of a torque and hp increase can we expect in our V-6 Camaros with the air-raid cai?

Jannetty Racing test a number of CAI last Sunday... These were V8 versions...

here's the thread: http://www.camaro5.com/forums/showthread.php?t=48202

and the results: http://spreadsheets.google.com/pub?k...=1&output=html

Airaid showed a peak HP gain of 9.2 and a peak TQ gain of 5.9.

Stock intake showed a IAT temp climb of 4 degrees (55 to 59 degrees)

Airaid showed an IAT temp climb of 8 degrees (55 to 63 degrees)

Stock fuel trim was -3%. Airaid fuel trim is 7%.

Some of it has to do with VNH... Vibration, Noise and Harshness...

Why not post this explanation here for all to see. I would certainly like to see it.

So after performing the IAT sensor relocate. Driving in heavy stop and go traffic. Heat builds up, and when the intake tube becomes heat soaked, the air is rushing by so quickly it does not have time to heat the air? Just wondering if the air might heat up on its way to the intake manifold, after the sensor read it at a lower temperature. Sounds like a great inexpensive mod!

The air is going through the tube pretty quick so it really should not heat up... and of course the stock sensor is at the beginning of the tube... so even if the air was heating up the stock sensor wouldn't measure that either...

The thing is the car's computer has the ability to adjust for a some error in these sensors... For example the fuel trims and knock sensors...

Hello CatiaJockey,

The Explanation would be that you are "Tricking" the computer into reading a cooler air intake temp, and that is going to cause issues with timing and can cause other problems down the road. The computer is also going to have to compensate for the improper reading.

The Airaid is already breathing cooler air and feeding the cooler air into the IAT sensor and it's getting a proper reading from that. The Inlet air is moving through that tube so fast that "Heat soak" is not really going to be an issue.

If a "Consumer" wants to do this mod, then that's up to them, however Airaid as a Manufacture does not recommend this modification.

Thanks,
David
