Any distinctive way of telling if your car already has stage 1 chip/tune/map?

[doublespeeded]

Hi guys,

I recently attempted to replace the DV valve (knowing that it Is a weak part) on my used 30,000miles 2012 (facelift) 2.0T TFSI Quattro, only to find that a piston DV was already in place.

I'm not sure if the piston DV had been replaced by the previous owner or Audi included the revision for the facelift 2012-2013 cars ... (it be good if someone can clarify and shed some light or confirm?)

Since im now preparing for stage II, for this car that I believe to still be stock...(I bought it from a BMW dealership and they did not tell me any history). is there any way of telling if the car already has a stage I aside from plugging in the OBD or something that reads the ECU software?

For me, my current other car/weekender is a 350wkw (475 Wheel Horse Power) EVO IX... so anything else feels de-sensitised and rather slow/er.. so I probably cant tell if it already has it.

Thanks

My 2010 has the piston version, fwiw. I also added the GFB upgrade prior to my tune.

Only way to tell would be to log boost or simply call the various tuners with your vin to see if it's on file.

Check if the speed limiter's been removed

You could test drive a stock a4 and compare. You should notice a significant difference

+1 on boost gauge. If you have a VCDS you could log boost that way as well.

[callaghan.]

Pretty sure Audi switched to piston-style on b8.5...

Take it to the dealer for inspection and see if you come out TD1

I vote you do this one.

I only asked as im not sure how honest tuners would be here if I took it to them for the stage II and then they just charge me for it, even if it had a software upgrade.

Aside from the Piston diverter, the only other mod I noticed was a ECS anodized blue magnetic drain plug. So I had a thought in my mind that it may not be bone-stock.


lets say this for e.g

Say it already has an APR Stage I software, but I go to a REVO tuner directly asking him for their Stage II... what will happen?
they obviously need to erase APR's software, upload their stage I (if its a pre requisite) and then their stage II? This way they'll need to charge the full amount anyhow?

I don't think they can add REVO stage II to APRs stage I?

The files aren't layered like that. You get one file. It's the same as if you buy a computer and want to put an operating system on it. You load the most recent OS, you don't have to load previous versions on your computer before loading the most recent revision.

See if it accelerates faster than a Toyota Yaris.....

[briansubsist]

If it happens to be an APR tune and it has more than one program (say stock and stage 1) you can see if this works on your car.

So that's only for APR, not for REVO or GIAC?

well the issue is, I wouldn't know the log in code to even try that ?

But would they be able to tell?... say for my example... at the REVO tuner. You ask them, 'before you start, can you check if it has any upgraded software on the ECU?'

[elscotto80]

Simply make phone calls to the various tuners, give them your vin and they can look in their database to see if your car has their software loaded.

Good idea, but mind you in Australia. Our customer service is shocking...

Whenever I deal with any vendors from the states, im always left thinking 'Geez, that person seems to actually care and value his/her job'

Over here its rubbish man... I think I did ring a workshop a while back for something similar on a another car and they didn't even want to bother to look in the system.

Yeah that's only for APR. Not sure on how to tell for other possibilities. Not every APR tune has a lock out code. Mine doesn't. You would basically skip the first step.

That's exactly what I did after purchasing my B8 last month. Having bought it from Audi Tysons Corner with an extended warranty, I was ready to raise hell if they'd sold me an unserviceable car. Service told me my car was not flagged 'M1', or modified, after running diags.

They ended up doing warranty work that very day.

Let me amend this post:

Today I installed Torque on my tablet/head unit and set up an OBD II to see how the car was doing. It reads that it's hitting 25psi peak with a sustained 22psi at full throttle. No codes thrown or pending.

Based on what I was able to see after a quick search (I'm at work) 22psi is not a sock boost level.

[willski]

Record video of a launch control 0-100km/h run. There's not much you can stuff up there, so if you get a time around 6 seconds or better then you can safely assume its not stock (stock quoted at 6.5 I believe).

hmm, 22 PSi sounds a bit high for a stock car.
For reference the EVO IX I have has a factory OEM setting of 18PSI for stock. a lot lower than Subaru STI.. but they did this to compete with their larger 2.5L (EVOS run the 4g63 2.0T)
Nissan Skylines 2.5 T run about 8 PSi OEM.

Out of interest, What is the stock boost level for Audi A4?

Record video of a launch control 0-100km/h run. There's not much<script id="gpt-impl-0.07795924682859712" src="http://partner.googleadservices.com/gpt/pubads_impl_103.js"></script> you can stuff up there, so if you get a time around 6 seconds or better then you can safely assume its not stock (stock quoted at 6.5 I believe).

So 6.5 sec expected for stock OEM A4 2.0T... without launch control?

anyone know the performance with launch control and without launch control?

Its kinda funny you mentioned, I just watched a video of a guy who posted a video on Youtube who claims that he had only Stage I mods (APR) and running on 93 Octane:



I dunno if what he has displayed is really achievable (as it seems fairly unlikely) compared to what really people have experienced with stage I or II.

whats your thought on that?... ill give it a try and let you know.

[Hybrid81]

I've read that OBDII sometimes displays requested boost, not actual. Not sure if that's the case.

That said, I'm hitting in the neighborhood of 6.5 seconds consistently, so I'm guessing the reading is wrong.

Yeah 6.5 is about the time with launch control. 4.2 with a flash sounds pretty optimistic

[Rollin Thunder]

I was 5.7sec 0-60 with launch control stock and I'm now at 4.3sec 0-60 with launch control after going K04 peaking at 28psi of boost.

K04 figure sounds good, but 5.7 stock 0-60? Seems about a whole second quicker that quoted, and should be good for a high 13 sec 1/4 mile. How was it measured?

Typo, meant to hit 6 not 5. Stock was 6.7 0-60. All measurements were done using the P3S gauge.

Im assuming that's on E85 aswell?

haha cool that explains it. I've timed one run at about 7 seconds 0-100 (62mph), have been meaning to try again

[Rollin Thunder]

That is on 93. Haven't had a chance to get E85 yet and time that run to see boost levels. The highest peak Ive seen was 28.4psi. On average it's between 26-28 on 93.

It should make the world of difference on E85 + K04, have you considered converting?

Don't need to convert, my car is E85 ready. Just fill and go. Haven't had the chance yet.

I just flashed APR stage 1 93 map.

After consistent 0-60 times of 6.5 while stock, I hit 6.0 on my first and only recorded attempt today after the tune. I got a good launch, but I'd imagine I could knock .1 or .2 off with a perfect launch.

Not even sniffing low 5's, let alone low 4's.

I used Torque to record the times. Maybe not the best way, but the only one I have.

That is stock boost levels. All VW/Audi ECUs log absolute boost pressure. That is, normal atmospheric pressure plus additional boost pressure. Pretty much every aftermarket boost gauge out there is calibrated to read "0.0" at what is actually about 14.7 psi aka 1 bar aka normal atmospheric pressure at sea level. You'd have to go to outer space to experience legitimate 0.0 psi of pressure. So when your ECU says 22 psi, a typical boost gauge would read about 7-8 psi.

How did this thread discussing ECU logging go so long without anyone mentioning that?!? Hope you didn't go put your car in a position to get TD1'd, of that was originally your concern.

[JinDIS]

ECU Tunes allow you to Redline the car in Park and Neutral
Also Rev limiter has been raised

Obviously the raised rev limit change would apply to every car, but does the park/neutral limitation apply to manual transmission vehicles?

oh, not sure about manual

Thanks for clarifying the boost issue. No TD1, but having new and very real issues since APR Stage 1 upgrade.

I have an APR stage 1 on my 2013 and it has a ~4k limit in park and neutral.
