Will the Injen intake work with my Cobb Stage X? Yes, for the WRX only and only if you happen to have a copy of their older Injen intake map. With their newer maps, the Injen intake map has been deleted though. It is always a good idea to use the latest maps, so current Injen intake users should strongly consider removing the intake and using the latest map.

Will the _______ intake work with my Cobb Stage X? Yes. But you will have no idea whether your car is now running lean, rich, or inconsistant without data logging and a wideband O2 sensor. So you might have to spend $300 just to find out you should sell your intake.

Will the Cobb SF intake work with my Cobb Stage X? Yes, according to Christian at Cobb Tuning.

Will the SPT intake work with my Cobb Stage X? Yes, according to Trey Cobb at Cobb Tuning.

Will XXX exhaust configuration work with my Cobb Stage 2/2.5? It was designed to work with a catless 3" exhaust, but you can run any other configuration down to a minimum of just a downpipe and be fine. Realize that the further from the specs you go, the more amount of possible less than target boost or power levels you will have. How much of an effect does a 2.5" catted exhaust, just a downpipe, or a frankenstein hodge podge of an exhaust make you lose....no one knows.

Will the VF-39 work with my Cobb Stage 2.5? Yes. But you will have no idea whether your car is now running lean, rich, or inconsistant without data logging and a wideband O2 sensor. So you might have to spend $300 just to find out you should sell your turbo.

Below are a list of things you can add to your Cobb Stage X:

P&P throttle body
High flow foam or K&N type air filter
Snorkle removal or delete
BOV
Silicone intercooler hoses
Silicone turbo inlet
TGV deletes (you'll need a fix for the CEL if applicable)
P&P exhaust manifold
Headers
Lightweight Pulley
Bigger TMIC
FMIC (this one is kinda shakey as results are a mixed bag, not sure if the FMIC or the associated intake is/was to blame)
Walbro fuel pump
One step colder spark plugs
Catless uppipe
Deadbolt Monster P&P turbo (stage 1 or 2)
Deadbolt Monster P&P VF30/34 (stage 2.5)

Remember though....anything you add to your Cobb Stage X will more than likely NOT give you the results that others who are tuned have seen. So don't think that headers will net you 17 WHP because that's what the manufacturer has on their website. So it's fine to add the mods now and not realize the mods' full potential or add the mods now knowing that soon after you will be getting a custom tune for the full benefits.

Cobb's mapping still uses the OEM computer's learning function. This means when you add something new and a parameter changes, you may see some differences either "good" or "bad", but after the learning process of the computer occurs, it will settle everything back out as near to it's original state as it can.

This info comes from a long time Cobb user who modified the dog crap out of his WRX and still saw the same WHP numbers as TBE only Stage 2 users. Speaking from experience here: I ran a JDM Ver. 7 TMIC, Borla headers, Perrin Pulley, Vishnu uppipe, fully catless TXS/Prodrive exhaust on a Cobb Stage 2 = normal Stage 2 on the dyno.

Where do I find the special Injen map?
Are we talking WRX or STi? What years?

www.cobbtuning.com

I think they did away with the Injen map. I haven't seen it in a while.

ah, maybe they did due to them having their own intake available. . .

Interesting, Cant say I see a point. :confused:

Compiling seems to the best step, indeed. *Insert Thums up gremlin here*

It's very important to consider the rammifications that a part can make to what makes a tune accurate.

you can probably ask folks if anyone has injen map. My buddy has Injen CAI map.

thanks for another FAQ UB

Sorry, there is no point to this post really. I mainly made it to refer people to as I see about 2-3 posts a day from people posting in the WRONG FORUMS saying "will headers work with an AccessPort?" and "will my AEM CAI work with an AccessPort?". I'm hoping that by linking to this post and closing the thread, it will stop me from going off on them to search or (OMG, no way!) actually visit Cobb's website and read the damn manual. :)

i have a quick questio. you said above, unabomber, that you added "JDM Ver. 7 TMIC, Borla headers, Perrin Pulley, Vishnu uppipe, fully catless TXS/Prodrive exhaust" to your cobb stage 2 but do you mean you just added it to the stock maps that cobb offers with the accessport?? i feel dumb but you said cobb stage x map and i went on there site and didnt find an X map. Unless you simply ment like adding that to a basic map (as in X = a basic cobb map)??

X = stage 1, 2, or 2.5.

I added those mods to the Stage 2 map and as well used the Stage 2 HWG map.

Unabomber thanks so much for answearing that haha i felt stupid for a little. You are one of the best people i see on this board. Some people would call me stupid and not answear me.

Unabomber thanks so much for answearing that haha i felt stupid for a little. You are one of the best people i see on this board. Some people would call me stupid and not answear me.

I'll "answear" you noob, just kidding. I don't know much about cobb anyways, lol.

I ran a JDM Ver. 7 TMIC, Borla headers, Perrin Pulley, Vishnu uppipe, fully catless TXS/Prodrive exhaust on a Cobb Stage 2 = normal Stage 2 on the dyno.

so all the extras get nulled by the ECU's learning? bummer. wouldn't that also occur if i put a lightened pulley and headers on and then got tuned? sorry about being slow, i just don't want to drop that kind of money for nothing.

i am not a noob to subarus but i deff am to the cobb ap haha

Here's a better idea... stop using Cobb's OTS maps and go with PDX's if you must run an OTS map. They are much better. Take a look at the logs from everyone with PDX OTS maps and then look at the logs of people with Cobb OTS maps. You will see the differences.

GREAT POST!!

-j

What would be the effect of Borla header on VF34 equipped WRX on a OTS Cobb 2.5 map? Do I need a custom tune?

EDIT: just got a response from Cobb (Christian) that THEY do not recommend aftermarket header on any of their maps due to inconsistency in performance.

Wrote PDXTuning an email, hoping to get a map from them.
Haven't heard back yet... hopefully I will.

Until them... I'm stuck with OTS maps.
There is no one in my state that does tuning, so I'm all alone. :(

Well with headers being said and I just found this sticky...I will add my headers (knowing I won't use to full spec) to my stage 2.5 setup, work on suspension mods and then get a protune...or something like that :devil:
-Joe

ps- Will need quieter exhaust though.

This info comes from a long time Cobb user who modified the dog crap out of his WRX and still saw the same WHP numbers as TBE only Stage 2 users. Speaking from experience here: I ran a JDM Ver. 7 TMIC, Borla headers, Perrin Pulley, Vishnu uppipe, fully catless TXS/Prodrive exhaust on a Cobb Stage 2 = normal Stage 2 on the dyno.

Very unbelievable, as any modification WILL INEVITABLY alter the performance of your car whether it be for better or for worse. Obviously running those additional upgrades will yeild different results maybe not nearly as much as possible with only running an off the self cobb stage 2 map. Its common sense. I will bet my own car that under a controlled environment (same temp., alt., humid., etc.) utilizing same car and dyno (of course) the results while running an STi TMIC, up-pipe, headers, cat-back, and pulley will yeild more power. Theres no way it couldnt, your car would be running so much more efficiently.

Say what you like buddy, but TBE only equipped Cobb Stage 2 cars where putting out my same WHP/TQ on the same day on the same dyno at the same dyno event at Mach V in Northern Virginia as me with the above mods + Cobb Stage 2. Believe when I say.....been there, done that, got the T-shirt to prove it.

Yes but thats different cars correct? Also its still not an entirely controlled environment..

scientific method and true controlled environments are impractical with modification testing. car to car is better than anything else. otherwise the testing would have to take place over a course of about a week.

With regards to that list of mods with no more gain just Stage 2 Cobb stuff - -

I personally think the only thing the WRX needs is a turbo...especially true for the 06's...then of course some more aggressive maps to use it...

Headers and intakes and exhausts are generally pretty good stock when it comes to most performance oriented cars...

You can spend 450 bucks on a TRD header for an AE86...but you don't need one unless you have over 200 HP (not feasible)....

Plus, maybe it's not the peak power, but how long it takes to get there...

Unabomber: is it possible that your HP/TQ curves are flatter/smoother than the other stage2 wrx 's ?

Smoothness is controlled by the dyno plot software, so that's a moot point. As to flatness, each car is different and as well, that can be changed in the dyno software, a lot of the flatness has to do with the tune or tuner's ability.

umm so instead of opening a new thread....will the Fujitsubo EL headers work fine with my Cobb STG 2?

What does fine mean?

The map wasnt made for them, so i'd reccomend a custome tune.

fine as in, ok i understand i wont get full potential of the headers but wont blow up my motor kind of way....

? I have a 02wrx lookin to go to the 18g with all the upgrades.Cobbs site shows their maps only support the 16g.Thinkin of going with Cobb AP, but if they don't support the modes I'm lookin for, what is the point of goin with the AP?:confused:Would I be better off with some other type of EM with a protune or what? Or will the AP get by till the tune?

sorry for my stupidity but i have a few questions and I have researched but can't find what i'm lookin for. the maps i've looked at say you need stock air box and stuff like that. well i have a cobb sf intake but no maps use it. so do i load that map and not get the most out of my intake until i pro tune?? and can i asume the same for my other mods like turbo back exaust not cats and uppipe all from cobb of course?

Cobb's intake was designed to work with the factory tuning. Therefore, to the best of my knowledge, it is approved for use with the Accessport It should be listed in the map notes, if it isnt.

With the Access Port, you should hold off if you have the cobb sf intake, and possibly other mods that aren't covered by the MAPS.

If anyone else has heard this and knows specificaly when plz let me know, but I hear that Cobb Tuning is releasing a better ECU for the STi, that will have a MAP available for cars upgraded with the intake, and other performance mods not previously covered.

The Cobb SF Intake IS approved with all AccessPORT users according to Christian @ Cobb Tuning. Reading the first post would have told you that. ;)

Ah, sry, I must have read too fast, but thanks for that.
Have you heard anything about Cobb coming out with a better ECU? All I have heard is that it's supposed to be better than the current Access Port, however, this was not first hand info from Cobb.

Look in the vendor announcement forum, details are in there. Nothing to get your panties in a bundle about in my opinion though.

why do you have listed in the 1st post that Accessport allows you to run a bov? does it specifically tune for the metered air lost? not that i want to waste my money on a bov but trying to understand why accesport would allow you to use one without the known ill effects. btw i love my stage 1 accessport can't wait to get my exhaust components and step up to a PDX tune.

Not the 06 WRX. (more than likely the 07 too)

Cobb's intake is approved for 02-05 WRX's. And for 04-06 STi's.

Reading the map notes gives me the info I posted.

A b s o l u t e ditto. I think I'm gonna PM unabomber because now, $845 in the hole, I just found out there is no MAP support with the cobb system. I could sell the system and buy a utec or a gun to shoot myself in the foot, but I think I already did the latter. *sigh*

Wow my browser sucks.

you are that angry that you can't run a bov, or you spent the money just to run a bov?:huh:

No I'm just angry that I can't run one -- its so far down my planned mod list I don't care right now... but I will later. Edit: And now to make things more confusing for me, I'm being told that I can... Well anyway, I don't worry about it much now, it just made me wonder, considering I stuck with the cobb route.

I am going to be getting a 07 WRX TR, and I am looking into the Cobb AP. Now I know it hasnt been released for the 2007 but I assume many parts would be the same as the 06 WRX.

Now I tried to search for the answer and I couldn't find it, sorry if it has been asked already

I am looking at getting the SPT intake with my 07 WRX, and in the future I want to get the Cobb AP 2.0 and I dont want to have any issues with it. Anyone know if it would work without problems (CEL, etc)

Thanks!

Hi Unabomber,

Are the various AP for an STi the same? Can I take an 04, put the 06 maps on it and then program my 06 STi?

TIA

Ray

I have a perrin FMIC with a blow thru boos tube(3 inch section where the MAF sensor is) Will that work with my cobb accessport? I have many mods beyond stage 2, my biggest and most important mods are UR GT30R kit and PE 850 cc injectors. I was told this blow thru boost tube will not work with a accessport and the MAF will be maxed out very very soon. is all that ive heard true?

i am putting a bulit 2.5 2.0 hybrid motor with a port and polish and an fpgreen, with meth injection can i run an ap with this setup or do i have to use utech

You can use an AP with any setup.

I ran a Stage 2 map with a TurboXS FMIC, TurboXS intakeand Invidia headers back exhaust. My car ran a bit rich but she ran strong as heck. Knowing tuning like I know now, I would have Protuned her when I had her, but she ran fine as she was. Like Unabomber said countless times. You will never know if your rich or lean unless you get a wideband O2 sensor and changing the intake before a turbo upgrade isnt really needed. It will throw the MAF readings way off and your AFR's will be all screwy in turn causing you to run rich, lean or all over the scale. Take it from someone whos put WAY too much money into subies. I did a lot of mods that were worthless just too look cool, not truly make power. Save your cash and get the parts you want then get a Protune. That, in my opinion, is the only way to go!

I am totally confused and am brand new to subies. I have a 02 wrx with intake and catback exhaust. I want to get the newest COBB accesport but will it work with my AEM intake? im sure this has been answered already but i just cant find it

Unabomber do you have any follow-up information on the FMIC that was tested? I really want to flash to stage 2 but Im still a bit unsure.

Has anyone experimented with FMICs and Cobb Stage X? Most of the kits I've seen conflict with the Cobb intake, but I'm hoping I can shift it towards the front of the engine bay to allow the I/C piping through. Any ideas?

FYI... this is just because COBB is so specific regarding the complications that can occur with the use of other other intakes. While, of course, I sure they want to promote their own products as much as possible, I would still like to use the COBB SR with whatever FMIC I decide on.

hrmm i got an injen

but not installed should i not put it in cause i just got a v2 ap

i was going to get it protuned tho neways

so can you run stage 2 on an 04 wrx with just a cat-back?

Cobb reccomends at least a downpipe for stage 2. Anything from the turbo back is basically ok for stage 2, but like it says in the directions, it will work, but not as well as it will with a full TBE.

Hi, im new here and I have an impreza STi 04' i just have a K&N box filter and the acessport v2 stage 1 the car is running perfectly and I just bought a Prodrive catback should I used it with stage 1 or i should make an adjustment in the AP??? like putting it in stage 2?
Thnks for the help......

leave it at stg 1 w/the catback. when you purchase a downpipe you can then move on to stg2.

i have currently own a 2006 sti, and i have uploaded stage 1,

i have just orderd a 65mm Cai from aps

my question is, which exaust should i use (and size) to run with the access ports stage 2 map.. I dont want an exaust that goes out at an angle like you see some aftermarkets for the sti's ( the ones that guys put on civics) i want 1 that just comes straight out. (and enough to cause chaos in my nabourhood)

thx

so instead of stating a new thread as someone said. i just installed an invidia dp so which map should i use from accesport?? i will be getting a protune on the 9th of feburary so this will be temporary but dont want to kill my car.

noonagon: Stage 2 if you've got a downpipe.

Can I put a VF34 on my stage 2 car and run it for a short while without the injectors and the other supporting mods? I'm just wanting to leave it at stage 2 but with the VF34 on and not drive it hard until I can lock down the supporting mods. I'm doing this because I know someone who will trade me a 34 for my TD04 + cash. thanks

Hello everyone I am new to Subarus as I just got my '02 about two weeks ago. I want to get an AP from Cobb after doing some reading on it. Just to clarify my WRX came with a Borla system exhaust and a Blitz bov but I shouldn't run the Stage2 until I get a downpipe correct?

Thanks in advance.

Edit: I also just lost my job and trying to save money on gas. Does anyone know how efficient that Max Fuel Economy map is?

Yes, you need a down pipe at least to run stage 2. Also I'm new too this but I think the blow off valve will make your car run lean. Form everything I have heard the stock bypass valve is better and safer. Do a search. Blow off valves = bad.
Also I'm Quartz hill. White 07 WRX not too many others around. Maybe I'll see you around someday.

Oh And I just got 29 mpg, running the economy map, have seen others get like 32. It works pretty good.

Sorry if this is annoying but i just signed up and i must have at least 3 replies so i figured why not ask a question?? Oh this is for an 08 sti

Does anyone know when the exhausts for the 08's will be released? SPT or Perrin? thanks

Hey guys if this is the wrong place please move it. I'm fixing to go to Stg II, full TBE exhaust, Cobb Intake and I'll be using the AP v2 to map the ECU. I know with my 03 WRX we had to install a resister when I replaced the downpipe. Can I delete that CEL with the AP or am I going to have to pickup that resister and install it?

HOLY freakin cow! Is it really that hard to go back and read the very first post on this thread and follow exactly what it says. He has all the information right in front of your face and STILL people like to come in here and ask their question that is already answered in the first post or has been answered in millions of other threads. Otherwise if your question is not answered either call cobb, email cobb, or check the cobb website. Stop being retarded. I have NEVER had to post a new thread to get my questions answered. Simply pm a member that might know what your talking about, or do a search. I dont know if im the only one who gets irritated by this but damn, I had to say somthing.

Might want to come off that high horse. Ever stop to think that someone posting something is a last resort? Were you there when the posted? Did you see them not search, did you seem them not look at cobb's website? Now I do understand some people post before doing the research but not everyone.

When I can answer their question from what I have read on the first post than obviously they didnt even bother to read the thread.

I have an Accessport v2, Injen FMIC, AEM water/meth is installed,and an FP Green goes in next week, along with 750cc RC Injectors, Perrin rails, Walboro f/p, etc.
Can I get a map from Cobb that's +meth, for the FP Green, do ya think, or does someone else have maps?

Got my question aswered on another thread

read people please!!! you're giving nubes a bad name, its bordering on we-toaded-ness.

if you have CBE =stage 1
if you have a downpipe = stage 2
a non OE turbo = the map for that turbo
air intakes are not reccomended with cobbs maps (use at your own risk)

and if youre fingers are broken:
http://www.cobbtuning.com/info/?id=3301

and if you have anything that isnt listed in the description from COBB done to your car, get a custom map or a tune for your car.

PDXtuning can help with maps
a local shop that can tune with cobb can help with the rest.

READ THE FIRST POST! there is a reason this is sticky!!!

I have a question that I didn't see covered in this thread.

If I have such and such parts to make it stage 2 and I should be using the stage 2 93 octane map and 93 octane gas...would using the 91 octane map and 93 octane gas be safer and also making less power then the 93 octane map??

Ok, i went to cobbs website, that really diddnt hold any information on my question, also ive read this ENTIRE thread, and what ive gathered is that you need a downpipe with a catback to go to stage 2 on the AP. Has anyone tried the Turbo XS Stealth exhaust found here: http://www.gnvmotorsports.com/catalog/product_info.php?cPath=21_48_174&products_id=276

I want to know if this downpipe and midpipe with the stock axelback exhaust will comply with the requirements for the "stage 2".

^^Please do the footwork and actually learn what an AP actually is before you insist on using one or asking questions about using one.

Why...:sadbanana: All of the information that you could ever need is available in HUGE quantities everywhere on this site and many others. Do yourself a favor, take a few minutes and READ the faqs. Your questions have been answered 100002034023000 times before. If you lack the common sense such that you really need to ask questions in this thread then you should NOT be modding your car. Again, there is a HUGE surpluss of information at your fingertips, please use it.

If you have a question about simple car stuff in general like what is octane and detonation, you do not need to ask unibomber as pretty much any joe schmoe could answer it for you, and a simple google search will turn up TONS of information for you.

If you lack the common sense such that you really need to ask questions in this thread then you should NOT be modding your car.

Uhm, then why the hell does this thread exist? If were not supposed to ask questions and we need to look things up for ourselves, then why not just close the thread?

Uhm, then why the hell does this thread exist? If were not supposed to ask questions and we need to look things up for ourselves, then why not just close the thread?

This thread exists because people repeatedly ask dumb questions wanting someone to spoon feed everything to them instead of digesting the information on their own. This site has more information stickied in the FAQ section than most people here would ever possibly need, and that's just this site. Here's a hint: Unabomber's Manifesto. The refusal to use the resources that are readily available to you on NASIOC and opting to ask the same questions that every other dbag who doesn't want to read asks is simply an indication of your lack of common sense.

I noticed on Cobb's website that it will only work on N. American ECUs. I bought my 05 WRX in China, it is left hand drive, ej20, but does this mean the cobb accessport wont work with my car?

Sure it's a real WRX and not a "copy"? :lol:

^^ Lolol

Has the BOV question ever been answered???

quick questions
cars current state- COBB catless DP, MBC set for 1.1 bar.

I just bought the AP V2, should I take the MBC off and let the cobb adjust, or leave it be and run ST2?
And this will remove my CEL for the catless DP correct?

BTW, this is an 03 wrx

like it was said before, the stage 2 ap was designed to run with stock settings...just mod your car as AP stage 2 says and you will be fine..... anything else just then do your protune

Take of that MBC immediately! You are not properly tuned for it. The AP will adjust boost as necessary via the stock boost controller, and will also remove the CEL light associated with the catless DP.

For some reason these forums will not let me start a new thread, so here is my question, or poll if you will...
What is best:
1) Cobb's AP (sold by Cobb)
or
2) Cobb's AP with Perrin Maps (sold by Perrin)

They are the same price, but I don't know if Perrin offer good customer support. I don't know if buying it with Perrin would spoil my warranty with Cobb? I have not found extensive info on Perrin's Stage 1 oct 93. I'd like to hear some opinions. If someone is using a Perrin Stage 1 oct 93 with the SPT CB on an 08 WRX, could you voice your opinion, please...
Any recommendations?
and yes, I have researched it, but not much turned up... except for the Perrin staff proudly discussing their maps in some threads here at Nasioc.
My roommate has the Cobb version for his Sti, and he did not speak highly of the Perrin maps... honestly, I'm far from understanding why...
Has anyone experienced anything wrong with the Perrin maps?
