CEL after ZZP Intake Install

I had trouble when I installed the Dejon Short Ram Intake on my SS throwing CEL, and it was MAF sensor related. I ended up buying an "air flow straightener" from Treadstones website, installed it and havent had a bit of trouble with it since(been almost 3 weeks and about 800 miles). Cost me like $30 shipped and had it in 2 days. It looks like a honey comb, slides into the intake tube before the MAF.

I think the boost comes on a bit quicker but it doesn't seem to be making more power, per se. That could be all in my head though.
In all honesty, I'm not sure I wouldn't mind seeing another code so I can, hopefully, continue to work with ZZP in determining if its possible to eliminate the issue for those with out tunes and it will run correctly as promised.

Hmm,
You know,the Cobalts have always had problems with air intakes.
You have 2 work on the 'tune' to get the Cobalts to work right.
This is just like a Cobalt intake, so maybe it to, has to be dialed
in right, with a 'tune'. Maybe that's why an air straighter, worked
on someones air intake.
When going from the stock HHR SS intake, & adding the K&N air system
to it, you don't have that problem, it doesn't cause the MAF, to be all
whacked out.

how did you come up with that hypothesis? could it be the fact that the Cobalt SS Turbo = HHR SS? we share the same exact everything (well just about), so of course we're going to have the same issues.
ever since i've joined this forum i've seen about 100 intake threads, 90 of which involved someone complaining about throwing a CEL after they changed their intake from anything but stock. the LNF ecu & maf are very sensitive. so once it notices a big change in air flow coming in, it'll try to accomodate that by bumping the fuel flow and things go finicky. the absolute best thing to do is to have someone with HPTuners run logs while you drive around and dial in the MAF precisely. you'll benefit more from this than just tossing in the intake and "riding" it out.

I've never seen a forced induction platform have such a hard-on for their air intake discussion, sometimes I have to check to make sure this isn't civicsi.net
. It's a MAF based setup, tuning is a given with most, you could get lucky and not throw a code, but you're still leaving performance on the table. My Dejon threw codes right after install too, I wasn't tuned...wasn't Dejon's problem. ZZP's wording here may be questionable, but every vehicle is different, if you threw a code and have such a problem, I suggest the following:A. Tune your car.
B. Leave it stock.
Or you can even do C. Buy a K&N, watch HotRodTV all Sunday morning get hyped up on the show's sponsored parts and just buy a Hypertech programmer and Magnaflow cat-back while shopping Summit Racing as well

Thanks guys. I didn't mean to sound like a whiner or complainer. I realize that when modding a car, not everything is guaranteed to go right the first time and it takes a bit of work. I appreciate everyone's thoughts and the wealth of information found here. I completely I agree that I just need to bear down and get it tuned for the intake (amongst other things).

you shouldnt have to get an updated tune to run this pipe....if you have a trifecta, or a ZZP tune, your stock turbo is pretty well maxed out anyways, more air in will yield more power.... if your car is 100% bone stock, yes, it'll likely learn down somewhat......but not on a car that is already tuned.
Learn down, & air turbulence at the MAF, are two separate things.
No where did they say that there would be any MAF issues like the Cobalt.
I'm thinking that they don't have a clue.
They just threw the product out there, without any testing.
They should put in the instruction sheet, the following:
Because of the air turbulence , that this intake causes, resulting in wacked
out MAF readings, you must 'tune' for this intake.
Most sensitive intake yet.

Yeah, because common sense doesn't dictate a change in a MAF based setup would skew readings, nor that the Cobalt is the same platform right?
Is Trifecta your only tuning option or do you have any experienced HPT guys in the area?

I don't have any HPT guys in my area that I know of. However, with that said, I have been studying up on the HPT and I believe I can write my own tune fairly easily. I hope to have the software in about a month. There are a couple of guys on this board that have volunteered to let me bounce HPT issues off of them as I move forward.
