Launching C6 S6 Tip

A6 All/ S6 All
#21

That’s a big car and the gear ratio isn’t good to help get you out of the hole.

I think the new intake carbon clean and properly maintained car should run right in your ball park. I wouldn’t try to really push the car too much harder until you either have something like a Jhm tune or your pre cats are removed. I know you have a free pass st the track but I would hold off going again until you have one of those things done.

Keep in mind the v10 you have isn’t the Lamborghini v10 it’s more like the S4 v8. A great motor but prone to issues. Taking it to the track is fun but the S4 guys quickly learned that the motors don’t like to be pushed unless unlocked and allowed to cool themselves. Doing a long search and reading the info dump lots of guys are getting replacement motors. Based off what I can see the replacement motors are due to obviously damaged motors. Cylinder wall scoring is one of them. That’s the same thing we s4 v8 guys get. Heat is the number 1 killer of these motors.

I would hate to see you guys start something along with a lot of testing at the track to go through the same things we did. Get some cool down parts. Contact CV in here see if he can help get you guys a tune to add performance but more protection.

Appreciate your advice Justin

I totally understand - although, I would not say I don’t run the car hard every day as my daily!

Short block was changed arleady 50k km ago - I did get to inspect the cylinder walls and there were some ‘lines’ visible, but nothing that would really catch on a ballpoint which I ran around the worst looking cylinders. That said, they certainly didn’t look as smooth as I’d have liked.

If I was super lucky & developed some skills, perhaps I could pull a high 13.8 @~170km/h but that would not really prove anything past what I have proven already. Just to be able to say I’m in the 13s :slight_smile:

I do want to get a tune in there, but at the same time I don’t want to double up - e.g. get a tune now, then do exhaust O2 delete/relocation, and then tune again.

The intake spacers are still in the works with JHM - I am about to send them a stock of pics which they asked for.

How picky are these motors? Coming from the world of Nissan, plug and play tunes are generally considered weak, and by far the best way is to go standalone/semi standalone and get your car tuned individually on the dyno. That is what I’ve got on my 180SX, and it made some great numbers all things considered (276whp, CA18, nistune, T28, fuel)

Have been speaking to a couple of the APR reps here who think they could work something (speaking of which, Muller & Muller, Sydney, seem to think they can tune the box for me too)

Can JHM do the most effective tune from such a distance, you reckon?

For the guys who aren’t aware of the B6/B7 S4 v8 tuning history, I guess it seems like there are a lot of good options getting these cars to run fast. However, in reality, there really is only one option for the tune for the B6/B7 S4s and the same for the v10s. That is a CountVohn/JHM tune. CountVohn is JHM’s Calibrator, who does all their tunes, just so there is no confusion.

The tunes that he did on the B6/B7 S4 adapted for mods and fuel octane automatically, and I can’t see the v10 tune being any different. So, you purchase the tune once, and it will adapt if you gut the cats or do headers, or exhaust down the road. All of these mods were part of the ‘formula’ that we keep referencing that worked so well on the S4s. IMHO, if you want to get the fastest, most reliable (CV tunes are safer than stock on the engine), v10 S6 at the cheapest price, then you’ll stick to the same formula.

APR already has a tune out. It has been out for years. ssicks has it on his car with filters and an exhaust. He ran an 1/8th that is almost identicaly (78.26 vs 78.56) to what you just ran stock.

http://audirevolution.net/forum/index.php?topic=3133.0

The reason why we make such a big deal out of the 1/4 mile times around here, is so that we can see what difference different mods make. Dynos can be tricked, and are useless. The best way to see how fast a car is, is to measure how fast a car is. Of course, this only helps the community if the member details their mods AND is honest. I dont think I have to comment any more on that.

What you can see is that ssicks (or the cars previous owner) wasted his money. The APR tune, fliters, and custom catback have given him nothing. If you want your money to be well spent, then dont make the same mistakes as ssicks.

Like Euroswager said in another thread… dont try and reinvent the wheel. All I am doing in the v10 S6 project is copying the same formula that worked for the S4s. CountVohn is doing the tune. Ill talk to him to see if it will be made available in the future.

I know everyone is interested in v10 parts from the project car. At the same time, no one wants to buy anything until it is proven. So, while youre awaiting results from the project, don’t waste your money on other stuff that is proven. PROVEN to be worthless!!!

#24

Very true I did say the APR tune was cookie cutter and really not worth it. Hell they know it! Invest that money in a good intake cleaning instead.

#25

How would you know the tune is ‘cookie cutter’ when you dont have the stock file to compare it to?

Why would you tell Paul to spend money on an intake cleaning when he has a brand new intake on the car?

You don’t have any experience modding Audis, nevermind tuning them. So stop giving people bad advice and spreading misinformation. If you want to continue with that crap, then go to another forum where it happens all the time. But around here, you reputation is shot, and your advice is worthless.

#26

I know he has a new manifold! I’m speaking in general! Not just to him!
I know it was because it’s obvious what parameters were touched and which were left alone. I am not trying to argue with you. Have you ever looked at a tune file? Please get off my case.

#27

The JHM tune on the B6/B7 S4 changed something like a hundred different parameters (number to be confirmed) while the competitors changed a handful.

CountVohn tunes for performance AND safety! Any idiot can turn off the factory safeguards in the tune, and advance the timing. That may give you short term gains, but result in permanent engine damage.

Then there are other tuners that play it safe with their tune, changing very litte. Result is a safe tune that offers very little performance gain.

If you want the best of both worlds (a responsive, fast, safe tune that automatically responds to mods) for any Audi NA v8/v10 car, then there is only one choice… JHM/CountVohn tune, period.

Wait for it, or waste your money on something else. Or self tune, and then put the damaged car up for sale two days later.

#28

I think maybe in the next couple weeks I’m going to finally get in touch with CV about a tune, maybe he can do something with the TCU too. My experience is identical to John F’s, the launch is either tire-burning fast or sluggish depending on the car’s mood that day, and shifts seem slower than they should be.

#29

I actually sent CV a message earlier, in regards to the tune on behalf of the group. It doesnt hurt to message him also, but if you dont get a response, dont take it the wrong way. He is super busy, and it will probably make the most sense to have a single point of contact for the update (i.e. ME :slight_smile: )

We are working on the TCU tuning for the project too. TCU tuning can for the ZF 6HP26a can only be done by a very small number of people in the entire world. Aside from CV, I think there may be someone in Austrailia who knows how to access the TCU on a similar ZF trans on a Ford (but hasnt done any tuning for an Audi). Since the TCU is inside the trans housing, the car has to be tuned onsite. Maybe the entire trans could be shipped seperately, not sure.

Ill try and get an update for you guys in regards to both tunes. But, please be aware that the likely response will be wait another three months. I know everyone wants this stuff right now, and I was kinda warned that creating the project thread would create this demand. But, I wanted to get the details of the project out there, to get people excited. LOL Seems excitement and patience dont necessarily go hand-in-hand.

#30

I’m also a member of the Patiently Waiting for a CV TCU Tune List ;D

#31

Not fair! You’re too damn fast already!!!

#32

Thanks V8A6 for taking a lead on this, lord knows I don’t have time to bug CV too much. I’ll wait patiently (sort of) for you to hear back from him!

#33

No problem man. Ill add you to the list of people to update, when I have more info on the tunes.

#34

That makes no sense. Why wouldn’t he want to have the strongest possible benchmark result?

Sure someone selling tunes and exhaust wouldn’t want that as it makes generating a delta vs. the stock benchmark tougher, but guys owning an S6 just want to see what the best they can do is.

#35

shit house lol

CoryCan has noticed something similar with his B8 A4. Sometimes it launches hard…sometimes it doesn’t. Sometimes he gets a 1.82…sometimes 1.99

#36

If you look at it like this. You can’t replace the 02 sensor without pulling the motor you can’t remove the precat without pulling the motor we already know what the cars are capable of. Without stuff to help keep the motor cooler like a tune and spacers your just pushing the car that’s already prone to have some issues.

From a performance only perspective it makes less sense but let the car run when it’s got more performance and preventive parts.

#37

Does that mean we shouldn’t drive them hard at all without a tune? Because I go 0-90 pedal to the metal getting on the freeway all the time… The car doesn’t know whether it’s a racetrack or if you’re just passing a truck…

#38

No. At the track your going full blast and then not continuing on. There isn’t a constant flow of air. Getting on the express way or even a excited run in traffic your continuing on at say over 60 mph. Plenty of fresh air getting in and past the motor the rad the oil cooler and to the same extent the exhaust. Your not going full blast and then stopping and parking the car right after for 45 min.

To me I would say prepare the car more for the track. You all know how fast the car is ball park stock with a carbon clean and properly working parts. There seems to be a few good parts coming out that can help. Start with intake spacers those keep the car consistent and stop pre heating the air before it even gets into the cylinders.

Cars can break at any track road or strip. I would rather have the car prepared with some mods to cut down on the possibility of ware and tare also thinking of getting some more impressive times. To me I benched marked my car and jumped into nodding it. I always feel like your not moving forward if your still stuck at the starting gate.

#39

Paul P, John F… I think I need a more memorable username!

All right, well I am being peer pressured locally to get back to the track with my mates next week - maybe I will have to risk it :slight_smile: No offence to you Justincredible, I understand where you are coming from.

OK - I will wait for the CV tune as well. I didn’t know the standard ECU could be so flexible. Sounds just right. I am in no rush either, so it suits me.

By then I may also have the intake spacers, and a solid plan for the manifold modification.

v8a6, I will PM you about the tune if you’ll be our CV Champion. You mentioned before that CV couldn’t do a TCU tune remotely - maybe something can be worked out between CV/JHM and Muller&Muller (Sydney) to see what can be achieved.

What is required to load a tune if we did have the files? Just a VAG-COM?

-P

#40

Because the TCU tune is not 100% guaranteed yet, I don’t feel comfortable commenting any further on it at the moment. I will talk to CV, and see if he is ready to share more details.

Also, there is always a chance that no TCU tune will be made available, now or ever. Please keep that possibility in mind. Until the project is complete, you never know what works and what doesnt. Or what is feasible to offer to others, or only makes sense as part of a crazy one off project. Ill try my best to relay the demand to CV, and share whatever info I can with the group here.
