Cool cool.

Can't wait.

Got all my powder to powder coat my engine..hoping to get started on that this weekend after we sc becks 2.4 ss.

 

Hahahahaha I missed this. Noone wants the bluelightning smoke show lol.

 

Replaced a cracked vacuum hose and its running much better. Still dies at stop lights though

 

So much air flowin through that head now the motor can't keep up lol

 

I'm not even boosting yet you ding dongs

 

toon needed

 

Glad to hear you say that. Got a few mechanical problems fixed today but still can't get it to idle at stop lights. I hope the problem is just off fuel trims or something like that

 

what afr's do you have at idle, what injectors? where is your idle set?

 

#80s, wideband isn't hooked up and I'd guess idle is around 1k not sure. When I first start it up it'll idle all day, just in neutral coming to a stop it'll die

 

You need to get that Wideband running asap. You could be washing down your cylinder with fuel. At least that was where I was before I got a tune. Your car uses stft and VE under certain RPM's could be stumbling over the table and after coming out of closed loop or dropping off MAF to VE. You should be able to idle on 80's at 800 rpm. YOur idel could be high though if your car doesnt go back into open loop. This was something I was seeing as well in my tune after having a few people trying to help me tune the car.

 

Shut off dfco and force the car in open loop and get ur VE and MAF tables dialed in then Turn the dfco back on..
Ur eather going stupid lean or pig rich wen the car comes out of dfco.

 

Drove the car for the third time today, idles better. I don't understand, it runs fine when I start it up. As soon as I get about five miles from home it starts misfiring and running like ****. Oh well, got the clutch broke in enough for tuning and it's gonna stay parked until I can get tuned.

 

I double check for vac leaks a ported head wont make the tune change that drastic

 

Agreed, driveability differences will hardly be noticeable from the head alone. Did you used to have a 2.5" Maf houing in your old intake and a 3" housing now? I know the cobalts are different than the redlines in that aspect.

 

I had the k&n idk what size it was at the maf... I'll check for more vacleaks. I know winter E can run like **** in winter but not like this. Keep getting po101

 

I'm sure the head added with the new intake is the culprit. How did you tune before without a wide band?
If idle is becoming a problem, you could just unplug the o2 sensor for time being.
Force it into open loop

 

I have a wideband, when I put my new dp on I forgot to put the sensor in so I just screwed a cap in I had from before I got the wb. I was planning on putting it in when I get my copper gasket.

 

Just put in an order at Jay racing.... I wonder if you guys can guess what it is....

 

044 pump I would imagine. I run that inline

 

I'm guessing ID1ks

 

Id1000 **** you nick lol
sorry I'm drunk haha

 

Bingo, advise you cheated lol I already told you

 

Got an email from jay racing asking if they were for turbo or supercharged cobalt......

 

Injector dynamics has the lnf list Idk why
Their direct injection so it's obv wrong

 

the new intake is the sole culprit changing the maf tube diameter will change the airflow 10to1 over a ported head that's my guess
