I bought the ss greddy elbow and after taking off the plastic stock one, I noticed there was a hose that connects to the stock one, but greddy doesn't have one.

Where would that hose connect to once the greddy elbow is installed? Where does that hose connect on the other end?

 

That hose is the AWS ( Auto warmup start) hose. You can plug that and not worry.. You should be able to see the metal pipe that it connects to on the backside of the UIM. Get a 3/4 inch hose cap and clamp, cap it and not worry about the annoying rev that happens when you start the car when cold.

Or you can get crazy if you swear by mazda engineers and have a bung welded onto the greddy elbow. I do not reccomend this becuse it is not needed. Just plug the AWS pipe

 

AWS , Auto warmup start ???? what is that ???? Try ,Accelerated Warm-up System

 

im sure he got the idea... auto, accelerated warm up whatever... its just another hose u should rip off and cap...

 

I heard that their are also side effects to capping it, I remember doing a search about it and finding some links. I remember something about oil spewing once in awhile and some other things....

 

No, oil only spews out if you VENT it. The only possible side effect of plugging the AWS is starting the car in extreme cold weather may be difficult. I have had no problems starting the car without the AWS in mid-30s (yes it does get that cold in Cali!).

Hah, not even close...

silvercivic: You need to learn about your car before you modify it. This is NOT a Civic. The AWS is a basic knowledge type item and you should know it before touching your car!

 

Go make some parts!!

I am sure he got the idea, but thanks for the correction Mr. perfect I don't know what i was thinking....

 

i bought a block off plate that replaces the metal pipe under the UIM. you could plug the hose, but thats ghetto to me. do it the right way and get a block off plate, its cheap at $5 or so.

 

if it is cold outside, you have to start the car in first gear. if your AWS is capped and u start in neutral, your car will die from the AWS trying to come on.

 

You shouldn't judge people by there screennames. I know this is not a civic dumbass, what do you think this forum is for...to learn! I've modified my civic back in the day, started in '93, finished with the car in '97...had an MR2Turbo & a WRX as well, but I've had this screenname since the start of the days the internet got popular and my first modified car. I've probably raced and modified cars before you even got your FD. Put it this way, I'm new to rotary...sometimes you got to ask questions to figure out the answer.

Everyone else....thanks for the help

 

I actually had a welder plumb in a nipple and replugged the AWS back in due largely to Max Cooper's experience.

He states that he DID have oil coming out of the vent and also "possible" stalling issues...

If I may speak for rynberg.. he was not saying it to be an ***, just more of a precaution. These cars are way too tempermental and delicate to be modifying without a good knowledge of how it operates. Not trying to say you dont know what you are doing, just a warning. On a civic ( for example), you may be able to get away with a few screw-ups. On this car, it can cost you thousands with one switched line.

 

Well said....that was my intention.

Silvercivic: My point was that you should be taking more time to learn the car before mucking with it. I know you just recently bought the car. Did you modify everything on your Civic the first 2 months you had it? Probably not. And these cars are 10x more complicated and easier to **** up.

I'm not busting your ***** just trying to save you some heartache/dollars, don't get so defensive.

 

The AWS is not needed for cold weather starting. It is responsible for that 3000rpm high idle when starting a cold engine. The purpose for this is to heat the cat up faster to reduce emissions.

If your ISC(idle speed control) system is working properly along with a properly adjusted FAST IDLE CAM then your cold start rpms should go about to 1500.

As I always advize newbs, get a copy of the Mazda Workshop manual. Section F is the most important as it covers all the engine control systems.

You are going to love the sequential turbo control system!

 

Thats odd; I capped the line when I installed my Greddy elbow and it still revs up to around 3000rpm on start up. Am I missing something?

Capping that hose doesn't dissable the AWS

 

You have to take the AWS out of the manifold too and unplug it.

 

Awww, now that makes sence. Thanks.
