hmmm thanks

 

I should have told him to buy them so he could mess up his motor.

He is in fact trying to run a turbo on a stock tune in the 2.2

Ask him how and he bullshits around the answer because hes a RETARD

 

seeing how garret and alpine (alpine with a piggy back, but thats still a stock ecu) already have one out and installed. and from talking to tnt it works great. now im just saving for mine.

 

Well I'm glad I just saved you all that money!

Here is a link to the Supported Vehicles List:

i am really interested in putting a turbo on my 2.2 but i couldn't imagine doing one without a tune or a piggy back. that just doesn't make sense otherwise.
so far i am leaning towards the garret turbo kit.

 

FYI a piggy back is a tuning source even if it uses the stock "tune" its modified by a piggy back. So then no more stock tune. FYI

 

You are right about not needing the bigger injectors.

You are wrong about flooding your engine. Bigger injectors if tuned properly WILL NOT add more fuel to your car than needed. and will not FLOOD or HARM it. If you just bolted them in without tuning you would do this. With tuning you will scale them properly and make the car run the same, if not a hair better.

You people who talk about flooding the motor have no idea what you are talking about in this matter, so it appears.

 

thats the kind of info i need, the positive kind where someone knows what they are talking about.
now i need to know how to tune my car.

 

Stevo take a motor and put in bigger injectors and see what happens. No tune

 

im pretty sure he said IF TUNED PROPERLY, what would be the point of not tuning it

 

You did not read what I wrote! I only said it about 4 times, because people are trying to spend all their time posting and not reading!

No tune will flood the motor hell yeah after all the injectors are 41% larger!

I was talking about Either tuning for it, or properly MAF translating to trick the injectors. And as for swapping injectors........I can't even tell you how many times I have done it, but I have built approximately 25 Stage 2-6 Cobalts.

Tuning = :-)

MAF Tanslator =

how do you trick the injectors, or do a MAF translate?

 

A MAF translator, like one sold by inense, alters the signal sent from the MAF sensor to the ECU. By translating the signal to the proper amount, you are essentially telling the car less air is coming in so it will pull the injector flow to match the needed AFR. It is a Ghetto Rigged system, but it works, just not how I would want my car tuned.

There were a lot of people using MAF translators here to make larger injectors work in the SS/SC, but now that tuning is out, those things are in the past.

 

not for 2.2s!

 

I believe the 07 2.2's are supported by hptuners since they switched to a ecu previously supported by them (e37).

 

Wow, can't believe I missed this thread.

Like psycosteve said, there wouldn't be a use for you to have larger flowing injectors.

Lets just try and get this straight so everyone understands...

The point of changing your fuel injectors is to keep up with the DEMAND of fuel NEEDED. If there is no need for more fuel, then there is no need for a change. It's just like changing your fuel pump thinking you're going to gain power...unless there is a need, there will not be a gain.

With fuel injectors, if your injectors are running pass 80% duty cycle, this is a great reason to change them. You don't want your fuel injectors to be over operated. Having excess kenetic energy could cause failure of the fuel injectors and plainly them not opening and closing fully or even as fast as they should be operating.

When it comes to the fuel system and operation, it's about need and control. If you're not capable of controlling, then you are going to be **** out of luck. Like said, if you put larger injectors in, you will run richer if you don't have a way to control it.

Understand that with your stock 24 # injectors, your computer runs at a certain duty cycle at idle and low cruising speeds. Putting larger injectors in and keeping that same duty cycle will make them flow more that is necessary.

You could use a piggy back unit that will alter the signal from the MAF sensor and PCM and with a slight larger size injectors like 34 #, controlling them shouldn't be a issue. When you start going larger, you can only change a voltage signal so much from the stock settings. If you think you can put 60 # injectors in with a piggyback (and your stock injector size is 24 #) and you think you can control it...you're a fool and you WILL flood your engine.

From personal experience (before I fully learned about the importance of fuel systems), I had a SAFC and 42 # injectors. I turned that bitch all the way down and it seemed to run ok but after a week...flooded engine. Car wouldn't even start. This was on a Sunfire but a L61 none the less with the same 24 # injectors. This is purely example but a piggyback will only give so many adjustments.

A device like HP Tuners is magnificant for things like this. Hopefully something will come out soon.

Now...another note:

The camshafts you have, I hope you realize that you utilize a Cam Sensor on your Exhaust Cam. Do the cams that you have have the provisions for it?

From HP Tuners website:

It's not out yet for the 07 2.2s

 

i would think so since there comp cams coming from turbotech racing. just stage one. if you were talking to me.

 

i didnt think you would need bigger injectors unless boosting or nitrous, to much fuel and you will just run like **** really a waste of money in my thought unless piecing together a turbo kit or something

 

You should really invest some time in reading! IF YOU TUNE YOU WILL RUN THE SAME! Bigger injectors are not going to make your car run like ****!

 

someone just put in stock redlinel injectors in there ion 2.2 the computer adjusted the a/f and learned the new injectors.. but then again he needs them because of the procharger setup hes running

 

No, it was for the original thread poster.

 

Check out this link. HPtuners must not have updated their site yet.

Well for one, that's a old thread...I knew they were in the process of supporting them but my thing was that it's not released yet. Wasn't trying to say that they aren't getting supported at all.

Sorry for the confussion.

 

LOL, that's a crock of ****! The computer CAN'T do that without tuning!

And I tried to put the 34#'s in the 2.2L Ecotec, and they DON'T FIT. I would like and explanation of how they got them in (it does look possible with a bit of modification), and how WaltDisney came back to life and Mickey Moused his ECU, because that "learning" business is a total crock! If you think the 2.2L ECU is smart, take a look at its tuning file. It's about as complicated as making Toast, dry toast.

 

ha now i know why your name is psycho stevo, you acnt post in a thread without busting a nut!
also i saw that thread about the 07 being supported by HPTuners, does anyone know what ever happened with that.
and just so you guys don't get your panties in a wad(psykostevo) i am working on a turbo setup, as previously posted. i was just wondering if it would be beneficial to put the bigger injectors in now. as i understand it it is not. so i will be hoding onto them until i'm ready for turbo.
thanks for all the great info, very helpful!
