Say Hello to the APR TT RS

[Arin@APR]

I still can't get over how beautiful the TT RS is in real life. Everything about it screams amazing. The engine is no slouch either. Stock, it throws you back in your seat. With only our ECU upgrade, it brutally rips you back into your seat. Still, the pursuit for more power never ends and the 2.5 TFSI is the perfect platform for more. This vehicle has quickly moved to the top of my favorites list and when we're finished, everyone will want this engine.

We took possession of the car on Saturday the 10th. The car was ordered in Suzuka Grey with all available options.

We began product work on the 2.5T last year and released software for the Rest of World (ROW) markets in October. We have already began to verify the software for US launch and expect this to happen soon.

This car is going to be part of a very special project that we are calling "Project Reunion". I cannot go into much detail yet but it will be a project that ties the 5cyl Turbo cars of yesteryear with todays modern 2.5 T 5 Cyl. We have been working on this project already for 8 months and cannot wait until the unveiling of both cars. I expect this to be sometime first of the year.

Needless to say it's a fantastic platform mated to a very proper engine. We already have fallen in love with it.

APR will be developing a full engine packages including our famous Stg 3 system. This includes intake, exhaust, software and Stg 3!

Stay tuned and as always... Go APR!

Stay tuned for the exciting updates along the way.

We are finalizing all that now. :-)

Nice! Thanks for the update. Can you confirm if there are actually any engine differences in the US-spec CEPB engines that result in more power potential over the original European CEPA models, and what those physical differences are?

Looking forward to the results

Hello!

[Dr. Bill]

Sweet!

Can't wait - you've got my ECU code.

[RhoneRanger]

When can we expect the next update?

[unclubbedvdub]

I am very much looking forward to your stage 1 ECU upgrade! I will be first on the list of buyers I can promise you that. So please please please hurry lol

[DrDomm]

Aside from the encryption, I wonder if the RS ECU has the same memory limitation as the TTS.

Do tell. I'm new to the TT scene.

[DrDomm]

Do tell. I'm new to the TT scene.

The TTS ECU only has enough memory for one program on it. In other words, you can't switch between stock and other programs.

Honestly, I would much rather say "Hello!" to the APR TT stage 1 tune for 2011 and newer TT 2.0TFSI's.

Come on APR. What fraction of TT buyers are TT RS buyers again? I know you're working on it, and I suspect you did the TTRS for the publicity bump, but get the lead out. Bring that stage 1 on the 2.0TFSI already!

Thank you for the input. Next time I'll ask Audi to not deliver our new vehicle till software is ready for all other vehicles. If that's not possible, I'll make sure not to share any photos, even if the vehicle happens to be older (in the ROW) than the new encrypted ECU's in the US.

dammit you took my post
x2 to this, again mainly cause i want more power, i know these things take time, and i know VW and Audi have completely F'd up the ECU's to be able to tune them.

Does anyone honestly believe we are not working on it?

Ouch. Thanks for the info.

We ran into this issue on the MED17 TSI ECU's as well but we were able to rewrite the compression and programming routines to make it work. We are investigating this same technique on the ME9 ECU's.

i know you are working on it, i hope so, you have my ECU file scanned from Goodspeed Performance.

[MoreGooderTT]

I, too, know that you're working on it.
Is the issue the new ECU, and the encription that it has to prevent tuning? At least tell us how far along you are, as in "The new ECU encription has been successfully cracked and now we're working on the actual tuning itself". That's what I want to hear, thruth be told. After all, isn't this the same ECU as is used on the 2011 GTI?

I'm very enthusiastic about what you folks do, but I'm also a very impatient person when it comes to things I'm enthusiastic about. At least you know you have me as a customer when it does become available, right?

GO APR!

Evidently, no good deed goes unpunished

Keep the updates coming

[R5T]

Stage III 600+ hp with flat torque line would be nice to see.

* new bigger Manifold turbo housing.
* bigger K24 instead of K16.
* 4" downpipe into 2x2.5" follow-up.
* Dual 100 cell race cat's.

Good to know Arin, thanks! When can we expect to hear the announcement regarding the North American TT RS programming? Two weeks?

Bueller?

APR won't know this...

Engine Codes
CEPA = ROW TT RS
CEPB = NA TT RS

CEP = Mechanical version of the engine

A & B = Power Difference via ECU only.

It's the same engine. The US version just has higher load request.

Thanks for the confirmation. Supposedly there are some mechanical changes listed for the CEPB in the ETKA, such as different crankshaft and flywheel part numbers. Maybe these just minor revs and aren't related to major changes.

[Jet jockey]

I'd expect close to 450hp and 650nm of tq

You have CEPA, CEPA V2 and you have CEPB.
A lot of changes where made with the CEPA V2 engine.

Changes in German.

Motor CEPA oder CEPA V2?
Hallo, um herauszufinden ab wann der neuere CEPA V2 Motor im TTRS verbaut wurde mache ich folgenden Thread auf.

In einen anderen Forum sind folgende Fakten gepostet worden:


Änderung der Werks-Verbrauchsangaben:


CEPA, 6-Gang (ab Frühjahr 2009 bis Herbst 2010)

Kraftstoffverbrauch kombiniert: 9,2 l

CO2-Emission kombiniert: 214 g/km (EU5)



CEPA V2, 6-Gang (ab Herbst 2010)

Kraftstoffverbrauch kombiniert: 9,0 l

CO2-Emission kombiniert: 209 g/km (EU5)



Ich konnte in Erfahrung bringen, dass der CEPA V2 ab dem 23.08.2010 im Werk verbaut wurde, natürlich dauert es dann noch Wochen bis zur Erstzulassung.

Bei folgenden Komponenten wurden die Teilenummern geändert:


- Kurbelgehäuse

- Injektor Kolbenkühlung

- Zylinderkopf

- Kurbelwelle

- Kolben

- Ölpumpe + Regelventil

- Ölmessstab

- Kraftstoffleiste mit Einspritzventilen

- Abgas Temperaturfühler im Turbo


Desweiteren folgende teilenummern die von aussen ablesbar sind:

CEPA

Zylinderkopf: 07K103063K

Ölmessstab: 07K115611K



CEPA V2

Zylinderkopf: 07K103063L

Ölmessstab: 07K115611L

[Arin@APR]

That doesn't follow Audi's engine code naming convention so I would not be surprised if the parts have no major differences.

[vw_fiend]

Thanks for the wallpaper! Can't wait to see where you go with this project. Loooove this engine!

[Marty]

We are finalizing all that now. :-)

Any updates 2 weeks later?

If you visit Petit le Mans, I'll let you "hear" one.

Big thanks to Arin and the crew at APR. I was down for my 8th year in a row at H2Oi and this time I had the new beast out down there.

Arin met me on Friday and offered to let me park the beast at the APR tent which = Awesome. Lots of looks and compliments plus 1st place in my class (the one and only in my class lol)

Let me say after a few chats with the crew the things they have planned are going to be phenomenal no doubt about it. I know it will be well worth the wait to see some of the outstanding products coming from these guys in the near future.


Stage 1 ECU with my name on it!!!! I can not wait..
