I am switching to SD do I still need a IAT sensor? I have a 2bar colbalt map

 

Yes....

 

yes...

 

yes x3

 

You do not need one, but it is really nice to have when tuning. You can tune around not having one though.

It is the best way to have the proper ignition advance and fueling ant different temps. It can also keep you out of trouble if things get heat soaked.

 

from a thermodynamics standpoint, the computer needs to know the incoming air temperature to CORRECTLY calculate mass flow thru the engine

I would never advise not using one

 

ok, i need to get one from a boosted car right? anyone know what parts i need?

 

Get one from a 1991 GMC Syclone from your local parts store...its threaded 3/8 NPT and plugs right in to the factory plug.

Just weld in a 3/8 NPT bung on your charge pipe before it goes in to the throttle body

 

thanks bro

 

anyone know the where i can get a 1991 GMC Syclone IAT? advance told me they cant get one.

 

efi connection has em....they are a sponser I think.

Since I m close to sand dunes, I see a lot of sand rails with no iat sensor. Its funny to me, cause the temp change out there is drastic. They run......but like crap. I even had to run my 3.3 suby for a day or two when I got it running with no iat. Complete pita.

 

i got one from the dealer. it was like 50 bucks.

 

Try someone else at Advanced, because they can get them. Or try NAPA. Any auto parts store should be able to get one.

 

I got mine at auto zone. Didn't the iroq's take them too? I thought mine was $13

 

bought mine advance auto

they don't call them IATs on the syclone...
should be listed as an air charge temp sensor...

part number is WT382P

 

You can still use the stocker. I drilled a hole in my charge pipe and shuved the stock sensor and grommet in there. It's a really tight fit, so that thing isn't going anywhere. The threaded sensor is cleaner and nicer, but the stocker works fine as long as you don't drill the hole too big for it to stay tight.

 

I also got mine from advace. I think it was 20 bucks or so.

ok, well i am going to talk to somone else at advance that knows what they are talking about.

 

I wouldn't want to boost too high with a stocker with the fear of it blowing out...

 

I put mine in with an EGR grommet. Just sitting there like that it was starting to blow it out at only 8 pounds of boost. To prevent it from blowing out, I tie wrapped it and its wiring to the intake tubing. If it blows out now, I will probably be around 50 pounds of boost, in my estimation.
