GIAC/AWE Stage II MAP/Boost Related Fault

[Jones2012s4]

Anyone with GIAC/AWE tune ever receive this fault?


Spirited driving on the highway today. Over 100 out with humidity, AC on. Just a picture of how I was driving. Not even sure when I noticed the CEL.

93 octane tune running with 94 octane in tank.

Weird! GIAC Stage II B8.5? Temps have been close to 100 all week and I drive quickly, no codes here

No no B8 :)

Driveability was not affected and everything seemed OK. Just would like to know WHY this code was thrown. Judging by the wording "Regulation range not reaches" I would tend to believe the boost is not where it was supposed to be at some given point during driving.

[Alex@TAG]

So we have seen this three - four times, all on 2012 S4's and what's weird is that all cars (including yours) are running the ROC-Euro intake. I replaced them with the AWE S-Flo and haven't had an issue. One customer even mentioned that putting it back to the stock intake (He has a Stage 2 AWE with GIAC DSG file) he felt pulled much harder than with the stock intake.

Now I don't want to say that the intake 100% was the one causing the issue, however once we removed and replaced it, the problem never came back up.

Give us a call if you want to speak more about this. :)

[drob23]

Hmmm...was really looking forward to checking out your ride, hope everything's AOK [:D]

[MrFunk]

Jones! You've had such bad luck with mods!

Strange that an intake would cause that... but if that's the common link I'd start there... Can you fit the stock filter on your ROC-Euro intake? I'm running the AWE intake with stock filter right now...

[well_armed]

I would double check the intake first before I eliminate it, make sure all the screws are down tight, everything is aligned.

I also doubt this is the cause.

[integroid]

One customer even mentioned that putting it back to the stock intake (He has a Stage 2 AWE with GIAC DSG file) he felt pulled much harder than with the intake.


I will also have to agree with this statement. It is in the mid 90's here and I switched from the Roc Euro intake back to my APR stage I+II and felt like the car was faster with the APR intake on. I dont have any real proof to back it up but did some hard runs with the rock euro then immediately swapped intakes and did some more hard runs with the APR intake. My guess is that the since the Rock Euro is pretty much just sitting in the engine bay sucking in hot air vs an enclosed intake sucking in more air from outside the engine bay.

[well_armed]

Did your customer have this (http://kalecoauto.com/index.php?main_page=product_info&products_id=8) installed at the same time?


Butt Dyno
$529.95
Just install a great mod like a cold air intake? Electric supercharger? Big Muffler? Magnetic fuel line ionizer? Awesome wing? Are you getting no respect from your friends for your newly found power? As we all know, these are high end and sophisticated modifications. Some may be TOO sophisticated to actually show up on a traditional dyno. So here we have: The Butt Dyno. Simply place it in the seat, and drive fast, weaving in and out of traffic. (On a race course, of course.) Now you can tell your friends with confidence "That oil-saturated air filter gave me 20 horses!"

Sorry, but your entire post is pure conjecture with aim at making a buck. Thumbs down.

[MrFunk]

^^ Interesting. I've always questioned the open concept in the engine bay with the heat of the engine along with the fact that air coming in fron the scoop will be dispersed throughout the engine bay and loose it's velocity and concentration... concentrated air from the outside directly into an enclosed area with the intake seems more logical to me for efficiency...

[Auditude2.0T]

I have tested the Roc-Euro against every competitor on the same night and same car via Vag Com Testing and V-Box Testing.

The Roc-Euro in both cold and warm weather out performed its competitors by a decent margin.

Apexit, Tsivas27 and Audisarecool were all there to see this testing being done.

I run the Roc Euro on my GIAC Stage 2 2013, I ran it on my 2010 GIAC Stage 2 and my dad runs it on his GIAC Stage 2. Never an issue.

No, let's speak more about this right here, on an open forum. Just so people don't mistake your post for anything other than what it is: a pure marketing ploy for you and your business partner (AWE).

Please explain the data that show the Roc-Euro intake is causing the OP's issue. Have you ran any tests at all to support your claims? If not, I think it's pretty outrageous to hijack this thread for your own marketing purposes (and at the same time bash a product that has proven real-world results).

Guys,

We're not here to sell a product, were here to make sure we help out a fellow member who is having an issue we have also encountered. Our solution was to swap to the factory intake. It could possibly fix the problem, which we have seen before.

Hope this helps!

[clochner]

LOL not so fast . . .

No, that was not your solution. That was something that a "customer" mentioned to you. Here's what you said (at 7:55 AM CST, before your 10:22 AM CST edit):

Own up to it, man. You hijacked this thread to serve your own purposes. And in doing so you (1) made a totally bogus claim with no supporting evidence, and (2) bashed a product that most of the fast guys are running.

And you're "not here to sell a product"? Give me a break . . .

[Bus Driver]

I just dynoed my Giac Stage 2 with RocEuro and got almost same numbers with my Stage 1 with AWE Sflo intake. In fact my torque is less by about 20nm. Temps here are about 93F. Did it with Dynojet and both runs at the same place.
Not sure if the intake makes this difference. Sold of my Sflo so looks like no chance to swap and retry.

Edit: Didn't see new posts, I'm not trying to stir anything here..also trying to figure out my small issue.

[AQuattro]

Dude chill out. His response was relevant to the OPs questions so hardly a hijack. The OP should try an intake swap and get back to us, simple as that.

My apologies if it came off that way as it certainly was not my intention.

I didn't get to drive the car, it was purely based off what the customer had told me. Bottom line was give the stock intake a run, if it helps eliminate the boost code than great. I hope this helps.

+1....
Relax man...

Alex has been nothing but honnest and straight up on the boards from day one. He generally adds value to conversations and states facts.
If it is true that they have seen this issue 4 times (we have no reason to not believe him) and if it is in fact true that each one of those included a common thread (the ROC intake)... and if it is in fact true that swapping out for stock or another intake resolved the issue (again no reason to think he is lying from his track record) then this is valid and good information for the OP to be albe to try out (for free mind you) to see if this resolves his issue.

Now if that is all fabricated then you have some validity - but we have no reason to believe he's lying...

((Vendors are here to sell product - so don't be surprised if they sugar coat posts with a little product marketing... as long as their posts are valid and value adding then have at it))

FWIW, I'm not sure a dyno will replicate the airflow that will make the Roc Euro shine over the alternatives. Fans can only do so much when you're just sitting in a bay. Real world testing has shown the Roc Euro to be superior as noted by Auditude. I'd venture that there will probably be some additional hot weather testing with a couple of different intakes very soon.

Type of dyno? Differences in weather between your 2 dyno sessions?

Post logs and some of us can possibly help you!

^Shit, totally forgot about fans.. That can be another factor as well corresponding to the intakes. I kind of don't think it's the Roc-Euro intake causing OP to have these codes but swapping the stock intake is worth a try considering it takes about 20 minutes to swap it.

[mikeh14]

I'm the customer Alex is talking about. I threw a check engine light not too long again and had the same codes as the thread starter, and they had been triggered 8 times. I also noticed what sounded like extra air blowing out the side/front of my car with the roc euro intake when it was WOT over about 4k rpm. And if I revved it while stopped, it would hesitate a little at 4k rpm too. I also ran a friend that has a 2013 stasis tuned S5, and we were dead even.

I replaced the roc-euro with the stock intake last week. It FEELS slightly stronger now, by I have no legit data to back that up. Just my feelings from driving it every day. I ran my friend again last night and pulled on him with the stock intake installed. The 4k hesitation is also gone.

I'm no mechanic, and I don't understand why pulling more air like the roc euro does would cause any issues (the more air the better, right?). Just letting everyone know my experience. It's a simple change to throw the stock intake back in and see if it stops the boost codes, and it had for me so far. And I drive my car hard

[MrFunk]

^^ Thanks for sharing...

Alex's point validated... End of discussion...

Jones - report back what you find...

Would you be willing to log with both the AWE and the Roc Euro on the same day? I'd be interested to see your results.

[JOS4AUDI]

I've had the same issue 106 degrees pushing car hard and CEL. Had it checked and cleared through TAG they are thinking roc euro intake. Something needs to be checked and done.

Do you have the GIAC tune also? Seems to be the common thread with these CELs. Switch to the APR tune and the problem will go away, and your car will be faster!

[apexit1]

I wouldn't go as far as saying it'll be faster. GIAC cars run real strong.

As far as the intake. I had APR stg 1+2 intake and did vbox. Went to a parking lot swapped to the roc euro and my car then set the record. Open element intakes don't do as well on dyno's becuase the air in the engine bay isn't circulating. To do a more accurate test it must be done on the road while moving.

I see my joke went over your head ;) That said, the fastest B8 does run APR

[itzjonjon69]

Just wanted to add my $0.02, i have the GIAC stage 2 tune and i'm running the Injen intake. As you all know it's hot as f*** in Arizona (110+ during the day and 100 at night) and i drive my car relatively hard and have never gotten a CEL. I had the top cover on, but currently i've been running with it off because i wanted more sound and so far everything's been good.

Humidity could also be a player...

[itzjonjon69]

I was actually gonna say that i think humidity has a bigger role than dry heat

[JOS4AUDI]

I really like the GIAC tune. The power is unreal love the car. I've only had one issue not continuos. I'm going to try a different intake I'm pretty sure.

[mikeh14]

Just got my AWE intake installed. Throttle response is better, and feels stronger than with the roc-euro as well. But I had a stock intake in between, so that's not a good comparison. I'll test it out better tomorrow

[apexit1]

I see my joke went over your head ;) That said, the fastest B8 does run APR

Sorry, internets can be misleading and yes the fastest and I think the next few all run apr.

If humidity plays a factor then maybe the straight pipe may be the issue. Can someone smarter say if air resisitance could lower the humidity of the air going to the motor.

I don't think the physics makes sense. Besides, even if it did somehow lower the humidity, that would mean condensation (water coming out of the air) would have to be going somewhere like when the temp falls below dew point.

But if a dyno is done in an AC room, the air would def be less humid.

[Jones2012s4]

My understanding is the P0235 code is thrown when too much boost is detected from the MAP sensor or being sent from the MAP sensor.


Car runs fine, threw the code and I didn't notice it right away until I was at stop light. Only had tune for a week.

I can try replacing stock air box to see what happens. Not sure this should be cause, never know though. I will report back.

Anyone know if there is some data I should log at WOT with VAG com that might be useful with back to back intake runs? Roc to stock.

[wwhan]

Sounds like the ratio of intake temp/pressure vs boosted Intercooled temp/pressure for a given RPM/Load is not what the ECU expects. It could be due to the way the ECU is calibrated.

Has GIAC ever done a custom tune on a B8 S4 with the Roc Euro intake? Is the GIAC tune optimized with the stock or AWE intake?

I am wondering if there are some value I can log that would show exactly this. The first part of your post.

http://www.goapr.com/support/datalogging.php

I'd log the values from the 3.0TFSI list in addition to requested boost. You won't be able to do all of them in a single run.

[Skidrowe]

Did you ever figure out what the issue between your intake and tune was? I think you should provide logs to GIAC in case the superior air flow of the Roc-Euro intake is creating a scenario they didn't test for. It would make me sad if their tune were to require their intake the way the DSG tune requires their ECU tune.

-Skid

[Jones2012s4]

This Friday it will be done. I doubt it's the intake as more of a combination. I will log airflow, req boost, actual boost, knock retard, rpm.

Need to get this sorted out before my methanol injection kit comes next week :)

I don't understand why you think GIAC would spend research and development dollars for a TCU tune for any other ECU tune other than GIACs? Are they suppose to do research and development for the other tuners? How are they suppose to figure out or try and tune for ECU variables they have no access to from a development standpoint. I would rather a tuner focus on making a TCU tune work as best as it can with an ECU tune they developed.

I have a Eurocode intake and my GIAC Stage 2 is wonderful, no issues, it sounds awesome too.

I just think it would be awesome if there were a way for them to have a generic TCU tune that would work with other ECU tunes. This would make their TCU tune an option to enthusiasts with other ECU tunes who don't want to switch. Assuming it's possible, it's up to GIAC to determine if the expanded customer pool would bring in enough revenue to cover the additional development cost.

More options are better for the community.

BTW, I have a manual, so the TCU tune doesn't really affect me.

Yep, there are options for the community, choice for DSG owners is clear until other tuners step up. I don't expect other tuners would risk developing a generic tune for TCU either, they all want to maximize their return, good business.

+1, Currently for the B8 DSG owners that want the TCU tune, the GIAC ECU tune is the only game in town. The only way to get a generic DSG TCU tune is with an independent transmission tuner, that does not do ECUs.

[itzjonjon69]

Just got the same exact CEL today... It was near 120 degrees here in phoenix with 23% humidity. I think it has to be the open intake and hot temperatures. Now I'm wondering because I removed the shield from the intake if it's sucking in too much hot air... Time to put the shield back on!

[BzzzBom]

Has anyone had this issue with any of the aftermarket intakes with the REVO, STASIS, or APR tune? If not, wouldn't that suggest that the issue may be GIAC tune related and not caused by the intake? I'm pretty sure that many if not most of the tuned cars are running aftermarket intakes.

[mikeh14]

FYI, I posted earlier in this thread that I was switching to an awe intake from my roc-euro one. I still got the CEL with the awe I take installed as well. I guess the cooking system will be my next mod...

I have the Eurocode intake and no issues with the GIAC tune, and I have seen quite a few now with AWE intakes as well.

Hi everybody

Since I made the upgrade on my S4 B8 to Stage 2 with pulley....my car is running only till 6000 RPM and sputtering on wide open throttle.....also I feel that there is a bpower loss to stage one.
VAG couldn't find any fault codes...someone had also similar issues?

[squashman]

Pure guess, but perhaps with the freer flowing Roc intake, the ECU is seeing higher boost ramp than expected causing the fault. With the stock intake or something more restrictive, boost won't spike or ramp as quickly, keeping the boost values within the GIAC defined parameters. Pure guess... but too much boost too fast could definitely be an issue (hence why the stock intake would solve the problem).

I switched my Roc-Euro for the AWE intake and still had the issue once. I'm thinking it might require the Cooling system and/or exhaust

to me it sounds like the intake is flowing more than the calibration was tested for, which explains why that intake produced more power then the rest

[shadycrew31]

Was this only happening with 2012 or other years as well?

Tag had mentioned issues only found with 2012, not sure if that was due to a limited customer base or the specific year.

[shadycrew31]

We have seen the code on 2013 vehicles also. After installing the AWE Heat-exchange it solved the over heating codes.

So for the 2012's the stock intake is needed, for the 2013's a charge cooler upgrade is needed?

No issues found on 2010-2011?

[helix139]

I'm sure on the 2010-2011s you will need to purchase an AWE full res exhaust from TAG to solve the problem, or perhaps a new set of forged wheels

Im pretty sure the problem can only be solved by bagging your car and making it scrape the ground like a 64 impala

Maybe they're out of stock on the coolers and need to substitute another problem solving product?

I heard AWE resonated exhaust solves the problem.

I have a 2015 s4 with a custom tune and pulley. I put my roceuro intake on after the car was already tuned. It wasn't right away but over the past month my check engine light has been coming on and then going off after a day or two. The code I got was p0235. I am surprised to hear that people suspect the roceuro intake to be the culprit of this code. Any more info on this situation? Car seems to drive fine overall even when light is on.
