I think it should be before the turbo, somewere on the chargepipe before the throttle body. I could be wrong tho....

you are correct sir.... be sure that you don't make the hole too big for it... just enought for the rubber bushing to catch it and fit it snuggly...

yes.... i've noticed that the car likes to stall and run pretty sluggish when the air temp sensor isn't in the charge pipe.. i had it hanging out and the car didn't like that...

I pulled the sensor and put a resistor in the plu for the sensor. Taped it off and no problems or check engine light.. The car always thinks it has cool air coming in..

It works. Just search AIT sensor mod on google.

With this mod no need to run AIT sensor.

This is for a Camaro but it is the same mod on my car.

http://www.installuniversity.com/ins...ricker_mod.htm

good luck. no check engine light.car thinks it is running on colder air and should run a little richer..

Any thoughts on this mod from others?

Input/Feedback please.

That's a lil confusing, if it's before the turbo there isn't a charge pipe. and on a charge pipe before the TB is AFTER the turbo. I would think mounting it after the turbo near the TB is somewhat more accurate.

Air intake temp sensor needs to be after the turbo, as close to the throttle body as possible so that it reads the actual temperature of the air going into the engine. Before the turbo is almost as bad as not having it in the pipe at all, since the turbo and intercooler change the temperature so radically.

Charger pipe is the one that goes from the intercooler to the throttle body. Which is of course is after the turbo.

Although, that's the reason all of my friend's turbo cars are running check engine lights. Because IAT is too warm. Seems even the intercooler isn't enough to cool it down.

Although I know for a fact earlier gens have a missing link that kills that or just an older computer that won't allow that type of code to be thrown. I'm not sure if we have anything like that..

Is there anyone on here that isn't running a check engine light with their setup?

IAT placement on a FI car is a trade off between fuel and timing precision. By the TB is better for timing, before the turbo is better for fuel. If you have fuel/spark control, you can take care of either case.

I don't get what you are saying, could you explain?

Not flaming, but what do either of those have to do with IAT?

dude...have a fitting welded onto the turbo manifold and then plug it into the fitting so that it will melt to the manifold create a secure bond and give you an acurate reading of 600+ degrees.....

dunno if u were just plain makin fun or jokin around but either way lol...

I plan on putting mine right near the TB, as boosted said... I dont have timing control just fuel so putting it near the TB, then using the VAFC2 for tuning.

The IAT has a purpose. It's not to just monitor intake air temperature for no purpose. What would be the point?

You have a MAP sensor that can read pressure, but not temperature. The MAP sensor ultimately controls the basis of the ECU's fuel map. But fuel is also dependent on temperature as well as pressure. There is more air in a colder charge than a hotter charge if both are read at the same pressure. Since the MAP only tells the pressure, something needs to be able to read that difference. The IAT does that. If the charge is colder, you'll need more fuel to efficiently combust it. If the charge is hotter, you'll need less fuel so you don't run overly rich.
That is what fuel has to do with the IAT.

As for ignition. A hotter charge is more likely to detonate than a colder charge. There are a bunch of sensor that work together to control the timing on this car. I'm sure we could throw the CPS and TPS in there. But ignition is also temperature dependent in a lot of cars. A lot of cars use the IAT for input in the timing.

The trade off I talked about is based on true temperature (throttle body) and intake temperature (before the turbo). Since the temperature before the turbo is generally a cooler temperature than the temperature at the throttle body, use the info above to see the tradeoff. If the temperature is cooler, more fuel is added. Hotter, fuel is taken away. (In most cases... I'd rather have more fuel than less) Depending on your fuel system... that might be the difference between running too lean, or running too rich. If it's reading the temp before the turbo, than it's cooler than at the TB (the true temperature), so the ECU would be changing the timing opposite what it should be if the IAT was before the turbo. That would make it more likely to cause detonation.

Surely I can't say that the IAT has any input on timing for our cars, but I can say that generally it does on most.

guns...didnt you think that you blew a head gasket...could it be because of this mod and it did increase timing to much...and caused detonation....


boosted2k2- do you think that the increase of timing would be enough to cause detonation...

or did i totally miss understand what is being said here

You understand. I doubt that the IAT would have that much control over the timing enough to do that. The cylinder pressure, fuel, and cylinder temperature could have caused it regardless. I just think of the IAT as a secondary sensor to help fine tune for conditions, not really overly control it.
