Who here actually blows through the MAF??

Brian - Why didn't you put the IAT on the boosted side?

Also, does anyone know the max temp that they can read?

One More Hole To Drill In The Hardpipes...

Also, the FMIC is so big that the intake temp is constant.

It's just stuck in the end of my airfilter..

not a good place to mount it unless you're running a full standalone and not even using this sensor. You should mount it as close to the TB as possible as that is after the turbo, after the piping and after the intercooler....it would give a more solid reading of what is actually going into your engine.

This is correct in theory, but I'm not sure how it would do in these cars. Although, I've always feared that I'd get some kind of boost leak through the grommet that surrounds the IAT.
 
I would set it in permanently (i.e. threadlock, crazy glue,etc).

also I forgot ....my haltech came with a seperate IAT sensor and I welded a bung and screwed it in seperatly. My stock IAT is just loose in the engine bay since it's not really needed anymore.

If you look at the Technical Data on the sensor, you will notice that is provides very little information to thow the ECU maps are changed. It does sweet dick... As long as it can tell the diference between +10 and -10 that's as technical as it gets...
 
and you dont think there will 10* difference between the air filter and TB? Is that what you're getting at? I don't understand why you think it doesn't control anything. The way i hear it is the IAT, MAF and knock sensor are the only things that have any input in the timing of the ecu.
 
What I'm saying is that the sensor is normally mounted in the airbox and has direct airflow all the time. It's important, however, It's made of plastic and used to take an average temperature. In a turbo the air can vary from hot to cold to hot as you apply the boost, so a stupid plastic sensor, isn't able to keep up with the speed of the my cars air charge changes. Let it sit at a constant temperature, and it will not try to modify the timing etc. That's the last thing I need is a sensor trying to calibrate the car for me. As it is, it works very well. I need the timing and ignition to be solid and not change so i can let the EIC-2 do what it's supposed to do without the ECU going crazy trying to modify something that it can't understand.
 
ok back on topic. i also have my iat before the turbo. so far so good. since goldpro is doing i might as well ask, should i downgrade to 2inch pipe? right now i have 2.5.inch.
 
offtopic. matty you find a deal on what we talked about? so far i am at 220 for a new one. so let me know.

the reason im changing to 2 inch is to reduce lag, i onlt have the 1.6 litre, but it rips, i have a video, awaiting someone on my other forum to host it for me, ill post it here when its hosted, what engine you got???? got any pics of your setup? what psi you running? i figure 2.5 inch for my 1.6 litre + my small t-25 is just alittle big ya know.
 
my charge piping is all 2.3" ID...I think it's WAY big..I fI switched down to 2" or 2.25" ID it would be a little more repsonsive...

dominoy2k1, not yet, I put in a quote and havent heard back yet...sometimes it takes a day or so.
 
dude once you are finished setting it up with 2inch pipe post your impressions on it. i might switch over to 2 1/4.
