Pushrod v8 S4?

[Quattro_The_Dog]

I have 2.8 cams already and I am getting this code change tomorrow plus the softlaunch code that makes you break traction to a certain speed then grab. I will post my own videos, hoping my catless full exhaust will sound like this. Tuner thinks it will be louder because it's twins. Answers the question what a high lift long duration 2.7T sounds like!

DigiCams??? Can you lay some knowledge on me about this?

You have me intrigued.

I'm with you diesel. Sound is cool but engine performance and how the car runs is way more important than it sounding like sbc 350. To each there own. But it's not for me. I hope you like it.

[Corradovolksb]

I'm pretty sure they are calling it digicam because it's the changes made in the tune that are causing this sound. It's for show only and does not affect anything other than idle performance as far as I can tell.

[rnagy86]

It sounds shit. It won't make a car faster, it's just circus, so what's the point?

[Monty23]

I remember seeing a 2013 v6 mustang with these digicams (tune adjustments to make idle spit and cough like the motor has big cams) last year at ATCO dragway. It sounded very unhealthy to me but the female owner loved it. To each their own I guess...

I am not hearing push rod V8, more like a flat head V8.

Don't be sad, no one is pushing it as a performance thing. Its just fun software mods, kinda like half the people with antilag don't use it to launch, they just like to make the car pop and spit at a stop or a gathering. Will update later with what mine sounds like, I won't run it all the time though, too old for that.

This is the truth, first thing I thought of when I read through this. 95% of people running anti-lag only use it to show off. No lift shift however is another story.

[GrapeBandit]

I know some diesel truck guys do something similar to make their trucks sound CAMMY. think they call it a lope tune

[Bordom]

Too bad I have a chipped ECU. Otherwise I would run this at car meets and what not for cool factor.

Can I copy the files/maps on the chip to a stock ECU and then add this in?

[GrapeBandit]

not saying its impossible to do it, but from what I gathered from multiple tuners is that its easier to write a file from scratch as opposed to getting into and "modifying" someone elses tune. talking about what bordom said.

[jballou]

Wow man, this is just as awesome as the Shifter Delete that 034 is selling.


When Can I get this add-on. I want to be like the Vettes that pull up during my car meet that sound like they are going to stall.

I see your point. I can live without it

The uber flow intercoolers and widebody are by far superior

Definitely can't forget the hella flush kit or adding a turbo blow off simulator for extra performance and style.

[BLK01S4]

and here I am trying to get a perfectly smooth idle. lol oh lord help us all.

[erykv1]

this has finally plagued the S4 world... lol. theres a similar tune floating around the 335 crowed that does the same thing. people charge $40 bucks for it, ridic.

[Heavy Winter]

I'm sad that this has made it to our platform.....

I'm just baffled that anyone would go to the trouble to own a nice European high performance sedan or wagon with an innovative and rich rally history and then go willingly spend time or money to make said car sound like uncle bubba's truck. . . .

Especially with ZERO performance gains.

Laughable, really.

[getslideways]

what is the code doing/altering exactly, technically speaking

Is it always on? or what engages it?

[GrapeBandit]

^from the sound of the video, it seems like he switches it on towards the end

In the link above it seems that the coding for idle is changed and you can achieve that sound by using the CCT at low pressure to induce overlap in the motor and turning off all knock recognition at idle. At least that's how I understand it.

Running the CCT at low pressure seems like it'd induce more wear on them resulting in more frequent changes

/\ I appreciate the link

Some will hate, some will like, such is the nature of the B5 community.

Whether I would implement it on my own car or not is not important, I just enjoy learning and tinkering, so I can appreciate the endeavor of this project.

[GrapeBandit]

just get fucking camshafts

whats nexta turbo whistler attached to your rear muffler

[getslideways]

just get fucking camshafts

From the link above from the guy working on the project: (people were upset that even the aftermarket camshafts weren't giving the "lumpy camshaft" sound the testers were hoping for)

I have had some camshafts in development that apply to the 2.7t v6. Its an aggressive set of intake/exhaust cams and in a beta test phase. So far the only complaint is that the cars dont "sound cammed out", basically people want the lope sound that you hear on an Evo or v8 or whatever has a different head design or vvt situation and is fighting misfire at idle due to overlap.

Our 5v heads, at idle with our high lift, long duration and advanced turbo grind or even the stock grind for that matter will never sound poppy and jumping the way that some want because there is no overlap. However with basically any cams on a 2.7t (or 2.8, 1.8, 2.0, ect) using vvt you can achieve a nice cammed sound by forcing overlap at idle and disabling a few misfire items and changing some codewords.

This technique is nothing new, in the Mustang world they call if Ghost Cams and Ford even does it with a special key on the Boss 302. Many tuner communities do it and I have not seen it in our world yet. After much bugging from testers and realizing I want it myself I set it up and it works well. I figure the VAG scene could use one more software thing.

Its like anything else, some will hate it, some will like it

Exhaust cutouts have in many occasions shown little to no dyno gains on this platform, however many people still enjoy those for the optional sound, regardless of performance. So this (in my mind) is just something similar, optional sound regardless of performance for those who are looking for it. If you don't like it, dont get it.

[GrapeBandit]

I tell you what, when I had the cat 3652 cams in my 1.8t, it was lumpy as shit

[Wagonholic]

details on that launch control . looks pretty awesome lol

[getslideways]

Hopefully we can get an exterior shot of it in action

[I-Reef]

I don't get the appeal of having a car that sounds like that at idle.

[AudiTechS4]

good thing is you dont have too lol. i can guarantee when i went to the drags this sunday people would have given this audi another look lol

[getslideways]

I don't get the appeal of having a car that sounds like that at idle.

=~= (we'll call this "usually equals")

lumpy exhaust =~= large cam =~= large lobes =~= more air in =~= more fuel in =~= more power

Look back to the muscle car days, cams designers would push the valves open for as far and as long as possible to try to get the most air in, usually to the point of rending vacuum assisted accessories useless at idle. So that sound became synonymous with power. As such, people often like that "lobey" sound. For example, "Thumper Cams" by Comp Cam exist in the V8 world because people wanted the aggressive idle sound without the disadvantages of a true "extreme cam".

Its along the lines of straight pipe exhaust (or exhaust cutouts as i mentioned earlier), most often a straight piped exhaust will not make tons more horsepower than a properly designed quieter one, but people still like "louder" exhaust because most people associate:

louder =~= more aggressive =~= must mean more power

However there are plenty of people in this word who would look at even a SAAC Twin 1 as "unnecessarily loud" and question why anyone would do that to their vehicular transport

So the difference between "cool" and "stupid" all depends on where in the world you are standing and who is beside you at the time.

Except straight pipe exhaust is in the pursuit of performance and has no negative affects except noise. This just makes your car idle like shit and sound like something it's not. Not comparable imo.

This is more like a 2.8 A4 with a turbo whistle and S4 badge or like removing the DV's for "turbo flutter".

This is called a "ghost cam" tune and can be hard on certain types of variable cam systems, it wont effect ours much for durability though... sounds mean!

You are certainly entitled to your opinion, but I would disagree with your "2.8 A4 with a Turbo Whistle" comparison. I would say it is more like running a splitter valve or muffler delete if anything, as its just exaggerating whats already there without measurable change in performance, not entirely pretending something exists when it doesn't.

Some will like, some will not, such is life.

Call me a helmet wearing window licker if you must, but a choppy idle like a large cam 440, that makes my pants feel tingly:




(if I could push a button for a quick temporary smile, I'd likely give in as long as it wasn't hurting anything, now I certainly wouldn't run around bragging about it or claiming its more than it is either)

All cars are just personal toys anyway, so if they are making their owner smile when they're played with, then thats fine by me

[phila_dot]

Personally I think you bought the wrong the car in that case, but...eh...god bless...salute.

Just so you know this isn't a push button thing, it's your new idle and I expect some negative side effects in the long term. To each their own.

I appreciate you weighing in on my vehicular acquisition choices to inform me of my erroneous choice, its very considerate of you.

Couldn't have said it better myself

but...eh...god bless...C'est la vie
