Has no-one APR flashed a 3.0TDI yet? Maybe I'll be the Guinea Pig!

[empiiw]

Has anyone flashed the C7 A6 3.0 TDI with APR yet? I'm amazed no-one has given it a shot yet. Have dome some pretty extensive searching and there appears to be one person who is trying to work out some kinks with a Malone tune, but I just have to say the gains show by APR look very appealing. I've been an APR fan for years with B5S4 B6A4 and B8A4.

I Just bought a 2014 TDI with 13k miles for 40k (felt good about the price point - it's loaded) and Im already looking at chipping it with APR.

Couple of other questions.
- https://www.goapr.com/products/ecu_upgrade_30tdi.html
APR has three graphs for 3 output models. I assumed C7A6 TDI is the high output model but wasn't sure - any idea?

- Had seen someone in Audiworld post the following and wanted to get insight from my trusted Audizine community
What scares me (a tad) is that it brings torque up to 479 ft/lb. The ZF tranny we have in our TDI's have a max torque rating of 480 and stock we have 428...

Well maybe I'll be the guinea pig on this one! I bought the car with the intention of doing the APR update

Thoughts?

Funny you post this, I was searching on it this morning. Doesn't look like anybody has publicly advertised they've done it. APR site is a bit confusing, the curves they show don't have stock specs that match closely or exact to our engines. I take the high/med/low curves to be level of tune. I'd be cool with the low one, a slight boost to what is there now would be fun.

VW has flashed them... hehe

The stock numbers are all a little different.

After more research on the ZF with some interesting comparison

The APR chip is supposed to bring up the Tq to 479. In Europe a bi-turbo TDI was released with more power - same transmission
http://www.automobile-catalog.com/ca...tiptronic.html
this had 479 ft-lb which is what APR is claiming to offer.

http://www.worldlibrary.org/articles...p_transmission suggests we have the ZF8HP55 in the C7A6 and although this link suggests that's rated to 550NM on ZFs own literature it shows 650 NM of max tq, which is 479 ft-lb http://www.zf.com/global/media/produ..._DataSheet.pdf

I feel like it's pushing the max for sure. Not sure how much wiggle room ZF left in the 650NM max. Interesting the Bi-turbo UK edition was rated all the way up to that number.

Another article about Bi-Turbo here

Torque curve look familiar APR?

If it's good enough for Audi in Europe maybe I shouldn't worry!

Nice!

[empiiw]

I'm shocked there's so few people interested in this. Maybe it's a diesel thing. Maybe it is a more boring option than the 3.0t and as such attracts less people interested in making more power.

[13allroad]

I was gonna give APR a go while they had the sale but didn't have the time. I am currently running the Chipwerke box and notice a nice jump in performance. Following the S4 chipwerke thread they notice a good jump in hp and tq with the ability of just disconnecting and back to stock.

I would like to see actual dyno from apr on the US 3.0tdi to see if the performance is worth it. In the next few weeks might make a apt. for dyno on my A6 stock and then using the chipwerke.

Revo still doesn't have a tune nor does GIAC. Wondering if APR can chime in on the thread to give more insight as to performance figures?

I wish there was an AWD dyno in our area. The stock power of the TDI is pretty impressive. I hear Audi is conservative with their stated power figures. Wonder if the gains are genuine too. Either way I may just have to use my Butt Dyno. Lol.

[Sean@APR]

The primary source of confusion on these cars is Audi. There are tons and tons and tons of ECU ids and just as many small engine variations. We've tried our best to put up all the numbers on the website, but without knowing exactly which variant you have, it's really hard to tell you what the results will be.

We've tried to come up with a relationship between VINs, build dates and factory calibration, but the answer has proved elusive.

About the only thing I can really say with certainty is that the customers that bought it have been happy with it. Use the 30 day money back guarantee and give it a shot.

[empiiw]

Sean. Can you explain the high medium and low output models as it relates to the c7a6. Are you saying all the cars have differing HP and TQ figures?

That's pretty much what I'm saying. There's something like 40 different ECU part numbers in the US for the 3.0TDI (Toureg, Q7, A6) over the last couple years. Some have different hardware, some are simply de-rated by the software loaded onto them. Without knowing exactly which one you have, I can't say anything intelligent about it.

I'm sorry that it's so confusing... we don't like it either. But, this is the hand we were dealt.

I believe that all of the US C7 A6 are the high output. The Q7s vary based on year and a few splits within years. The Touregs are (I believe) all low output. As soon as I say this stuff though, somebody will show up with one that makes a liar out of me.

How can i figure out which I have and what I can expect out of a tune. Happy to invest in APR but would like to know the gains. The low output gains for example are very slight

[13allroad]

Could we pm you our ecu I'd number to see if it can be flashed and if you have any figures on it?

Honestly, the best thing to do is go to a dealer that has a dyno and have them do before and after runs. If you're not happy with the results, take advantage of our money back guarantee and you're only out the $50-$100 for the dyno time.

In theory, yes. In practice, I've been on the road for the last 3 months and am home for 11 more days before starting out on the road again for several months. So, I can't promise that I'll respond in a timely fashion.

I'll email the guy that manages our files and Arin (handles the website) and see if we can put together a list of ECU ids and power outputs and put it up on the website. That might help simplify this.

Don't have one anywhere close

and risk TD1? Unless when uninstalled it's not detectable. Any feedback on that would be awesome!

YES! This!!

It would be considerably more useful than three random output modes that cannot be matched or cross-referenced in any useful way to the vehicle anyone is driving.

Not flashed with APR on my tdi but I do have dpf delete and JR auto performance of Canada tuned my car with handheld tuner, so no need to go to a dealer. We are almost done finalizing the product and then I will dyno and post results in seperate thread. Sorry op not to derail just wanted to let you know another option from JR performance and from Someone who has tuned their C7 diesel.

[empiiw]

Not really derailing at all. At this point I've not heard anyone post positive feedback on their personal experience tuning a c7a6 TDI. Good to hear. Please post as you have more data.

[EYE4SPEED]

I did this with my 335d and it was noticeable. I would do the same thing with a European tune once this diesel issue gets resolved.

[13allroad]

Will post hp/tq numbers on my a6 tomorrow using the chipwerke box.

Why wait just out of interest?

[empiiw]

Sean or anyone. Do you know if you can uninstall the Ecu flash without Audi being any the wiser? I like the try before you buy aspect, but don't want to roll the warranty dice unless I know I'm getting the higher output results. :)

Your stock file will be put back on the ecu but your flash counter would be increased. With that being said various threads post different results. At the end of the day you need to have a good relationship with your service advisor.

We reset the flash counters back to their original value, so that's not a concern. I can't promise that Audi can't see it (since I don't work there...), but I can say that we have hundreds of people flash back to stock every week for service and the number of TD1s can be counted on your hands.

We get phone calls almost weekly, maybe month about the 3.0TDi tuning. The 3.0L TDI's are very impressive and respond very well to the tuning. We have flashed a few of these cars and the owners were very pleased with the results. I happened to rest driev my first tuned 3.0T in a Q5 not too long ago and was highly surprised at the power and torque the car made. That torque though, is something to be impressed with. Instant spool up and instant torque making the power come on right away... no lag.

All this review coming from a 600rwhp /1200 lbft Duramax Diesel Silverado owner...

If you go for it you will not regret it in any way shape or form. Feel free to ask any other questions.

Thanks,

Greg

Are you talking apr Greg? Also you mention the 3.0tdi and then the 3.0t q5 above. Did you mean the TDI q5? Thanks for the input.

Yes, APR. My mind has been streamlined lately with posting 3.0T, I meant to Say Q5 3.0 TDI. I have driven dozens of 3.0T's.. The TDi is one fun car to drive once it is tuned.

Just traded in my S6 and my Audi rep was very concerned about the tune since they had an S8 come back in tuned and the customer didn't tell them (nor did he unflash it)... cost them $12,000 to CPO for some reason after that.
We unflashed, they did their thing. Trade is final, no problems at all.

[slevin]

Yes, someone post results !

I've had my 2014 A6 for 1.5 years now. Been wanting to do an APR tune on it, but wanted someone to post real results on it before I pulled the trigger.

[empiiw]

I'm going to wait for the TDI issue to blow over before I tune. I'm expecting they will overwrite the ECU then and I'd prefer not to get flagged TD1
