I am finally in the process of putting my turbo on and I am trying to figure out if I am supposed to put my IAT sensor into the charge pipe that runs to my throttle body like it is in the stock intake arm. It is a 99 Civic and I just don't recall seeing it in any pics of other peoples setups. I tried to search but couldn't find anything. Help me out if you can. Thanks.

 

Why do you want to do that?

 

I am not sure if that is what I am supposed to do or not, that is why I am asking.

 

just think about it... if you mound the IAT Sensor in the charge pipe you read cooler air temperature as in the intage manifold. so your ecu will enrich the mixture...

i've never seen any turbo setup with the iat sensor at a differenct place, only if your intake mani didn't have any mounting holfe for the iat... not normanly you won't need any change with proper tuning.

the only issue with putting it in the charge pipe, is getting it to stay in under boost.

i did this on my 99si, i put the IAT probe in the charge pipe, took a zip tie, went around the pipe, between the 2 wires ont he sensor, and bingo, DONE.

unless you convert to the OBDI style manifold with the bolt in sensor on the manifold you need to do use this method.......

just dont wrap a bunch of tape around it and shove it in the hole, thats ghetto and the tape ends up in the motor..............

 

i have a GM AIT in my charge pipe a few inches before the throttle body. the reason why I put it there is so that I can see the air temps actually going into the engine under boost and vacuum. I also have another AIT before the intercooler. I wouldn't recommend putting a factory Honda AIT in the charge pipe because it will get heat soaked. Why the sensor get heat soaked you will get in accurate readings

 

I have a machined block I had made for mounting the acura mani mount sensor on the charge pipe. not using it on my new setup if you want it



here's the sensor I used you can pick up at acura...


works great

 

Thanks for the replies, I coincidentally have a Z6 manifold on my Y7 which has the sensor in it also so I guess I will just use that one to simplify the matter.

LOL SOOOOO over-engineered.....I like it!

 

yeah i left mine out not really knowing what to do with it and i got to the dyno for the tune and he was like you didnt put the iat sensor in i was like i didnt know i needed to...lol

 

if you use a type r manifold you can just rewire it and connect it on the manifold that is what i did on my 2000 si

 

Just put it in the air intake for the turbo.

 

what the difference between mounting it before and/or after the turbo. (From what i know of uberdata./crome does IAT even have any effect on calculating fuel ratio?) im debating if i need an autometer air intake temp gauge if I can datalog IAT.

 

well, the difference between putting it before and after the turbo would be the fact that the air temp increases when it gets compressed.
So putting it before the turbo, too cold of a reading
after the turbo, but before the intercooler, to warm of a reading,
in the intake manifold, can get heat soaked,
A few inches from the throttle body on the charge pipe, just right

 

is this what you're referring to?

this is Marauder's setup:

If it is what you're talking about edelbrock places it on the air inlet on the turbine side.

 

i stabbed a hole at the coupler right before the tb with a screw driver, then poked the iat in tehre, and zap strapped it down

its ghetto and it works :D

 

GM air temp in the charge pipe= less errors due to heat soak...

 

how do you run the GM AIT? it has the same output as the Honda IAT?

OBD2 ECUs 'expect' the IAT sensor to be in the intake pipe (cooler temps than the intake manifold) and OBD1 ECUs expect it to be in the Intake Manifold (expect warmer IATs) and they account for this factor differently.

The calculation that happens inside the ECU is a little bit different for each generation of ECU.

I say try a variety of locations and see which gives you the best drivability while tuning.

 

99 hybrid, what EMS are you running? Im going with the AEM EMS and the GM sensor is probably alot cheaper the the AEM IAT.

 

I'm confused. I made it through my first DIY turbo kit without having to re-loc the IAT. . . under what curcumstance is one required to do this?

 

I have a Y7 with a Z6 I. Manifold and my IAT is in the Charge pipe..I drilled a hole close to the TB and JB welded in there...No problems by running it there.

 

Bump - still confused.

Over-engineered by an engineer though
