was wondering towards the end of the instructions it talks of some power adder technique which is off road use only. I was wondering if people have installed there CAI like that and if so does it burn a lot more gas or there is no difference. Also how much of more HP do u actually get from doing the mod that way.

 

I did that last step. It's very easy--just involves re-location of the temperature sensor. I did not notice any change in my mpg. Not sure how much HP this adds. I think this might make it not CARB compliant (not sure).

Bottom line: do it.

 

It says the following on the instructions I got:

"Optional Power Adder Note: This is for Off Road Use Only and voids CARB Approval!"

 

What is carb approval exactly?

 

I have the power adder and I did a MPG check with the trip computer yesterday night...

it was a really cold night and i think that because of that the temperture read by the sensor was really cold compare to warm days

so i got 27mpg going 75mph with cruise control on. when am suppose to be getting around 31mpg.. I think it might be cause of the AEM but i'll relocate it to the stock position soon and see if it makes a difference.

 

California Air Resources Board.

They have very strict emissions standards/tests and this could cause you to fail their tests.

 

I vote to leave ithe IAT in the stock location. IF moved to the cooler CAI location, you are just telling lies to the computer. I love the computer, it is there to make the most HP as possible. But, the computer needs "good data" to make good decisions. Go telling it lies, and you know, "garbage in, garbage out".

The purpose of the CAI is to allow cooler air to be ingested by the engine. And, this is being accomplished !!!! So, let the computer do it's job of seeing the true air temp at the stock IAT location so that the computer can use it's programming effectively.

Here is a link that is dedicated to discussing the pros and cons to moving the IAT sensor.

Be warned that some people called the IAT sensor as a O2 (oxygen) sensor. It is *not* an oxygen sensor. It is an Intake Air Temperature sensor.

I did this originally, but moved it back after about a month. Moving the IAT sensor causes you to run rich (use more gas); it also makes the CAI louder. The sound is cool...using more gas isn't. The trade off of gas for sound isn't there for me...the power increase is negligible, you won't notice it. Gas for power, yes; gas for sound, no.

 

i really doubt that the decrease in mpg is that significant, but if you have proof that the decrease is significant would you please let us all know

 

I dropped from 21 to 18...after moving it back, I went back to 21 (sometimes 20), where I stay consistantly. Maybe you wouldn't consider a 3 mpg change significant, but I would...and the more your drive, the more it adds up. Why increase your costs for a couple more decibles of growl when you stomp it? And for those that want to talk about the power increase...you'll get more from a Type R badge.

 

If you read this older thread that I referenced above too

https://acurazine.com/forums/showthread.php?t=128867

You will see that many of the posters in that older thread said the same thing -- LOWER MPG with no significant increase in power.

 

another thing to add, im sure you guys all know this but the first 200 miles of driving is not accurate because the ecu needs time to adjust to the changes made

 

ok i just got installing the AEM. damn it was a bitch, took me 5 hrs. body is aching all over. Most of my time was wasted removing the stock resonator (2 hrs). Only thing i wanted to ask is i lost about 1.25 cups of coolant, because i didnt bother with the gallon of drainage. However storage box still reads max so should i worry about adding more or just leave it?

 

Does it read MAX when the engine is hot or cold?

I had the same problem w/ spilling about the same amount & went to my dealer and they refilled it to the proper level for free. The service advisor told me that it should read close to MAX when the engine is cold & read close to MIN when its hot. My coolant was way below the MIN level when hot. Let me know if I was informed about the coolant level, but it seems right.

 

it read max when cold, didnt really bother checking it afterwards since i was soo tired. i will check up on it later today when i go out and see what it says.

 

Check it over the next serveral days. The reservoir works by siphoning. So, the car will need to go thru at least one (and perferable several) heat cycles (cold engine to operating temp to cold again). Then check the reservoir's level.

What happens is the radiator will purge (overflow) into the reservoir when hot, then as the radiator cools the water in the radiator will contract and creat a vacuum to siphon the coolant from the reservoir back into the raditor. When the radiator is low, the air within the radiator needs to be purged when getting up to temp.

 

Ok so i reattached the intake air sensor to the stock location and i still get 27mpg going at 75mph.... this is after driving the car for 1 1/2 weeks around b4 retesting already so not a computer adjusting issue. My other thought is that maybe its the cold weather now? leading to more air cause its dense and using more gas because of that?

can another MT TL try this?

 

EPA equired winter blend gas is at the service stations after Oct. 1. You will get better mileage with it, so you may be comparing the mileage witht he same fuel. And as you said, its cooler outside and that will help a little.

 

Have you reset the MID to get an accurate MPG reading ?

yeah i did what was done as the link above.. he got 31.. i get 27 at 75. and at 85 i got 25 unlike his 27.
