Hi all,

we have now finished the development mapping for the new S3.

The car uses was a 2014 Sportsback S-Tronic, as it came from the factory with no hardware mods.

As std, it made 293bhp on our Dyno Dynamics based dyno, they are officially rated at 296bhp.. Car has covered around 2000 miles so still pretty tight.

After countless hours of tuning, data logging, tuning, dyno runs and road tests, the car made 358bhp, and 382lbft of torque. A gain of 65bhp and 100lbft.

Dyno graph:



While dyno graphs are interesting, it's the real world performance that matters.

All VBox runs were done in the wet, so far from ideal. The important thing here is the difference.

Std Results:
0-60 4.71s
0-100 11.19
1/4 mile 13.24 @ 108mph





remapped results:
0-60 4.28s
0-100 9.6s
1/4 mile 12.63 @ 115mph





Of course every car is going to perform slightly differently, and we can tune to any spec or request.

Price for Stage 1 is £400 including Dyno time.

Thanks, Rick

Just to give you guys some advice when using the vbox.

To get an accurate 1/4m time, you must have 1 foot rollout selected in the setup menu. When racing your car at a dragstrip, you line up at the stage lights with 1 foot between the front wheels and the first timing beam. The vbox replicates dragstrip use for individual testing by allowing the 1st foot of movement to be discounted before the timer starts.

This function on the vbox should only be used when timing a 1/4m specific runs, not for a 0-60 or 0-100. If the function is left on in the setup menus, the vbox display (on the unit) will typically show a 0-60/100 run 0.2-0.3secs quicker than what it would be with it off. However, when you come to plot the data in the graphs, it shows the correct 60/100 as the performance box tools works it out that you had it selected in the menus.

Your graph tells me that your 0-60 and 100 times are correct but your 1/4m time is likely to be incorrect (If you did not have the 1 foot rollout selected) It will be slightly quicker than that.

You may be already aware of this but just thought I'd raise it just incase you weren't.

Hi Leo,

Thanks for your post. I've experimented with the roll out feature before and as you say it makes a difference. For these runs it's the difference that we are really interested in rather than absolute times, especially as it was wet!

0-60 4.7s on wet road! Those things are quick enough out of the box let alone with a stage 1! feck!
 
These cars are ****** capable, in the latest autocar the golf R has more lateral wet grip than a GTR
 
The gen 5 haldex is better at putting the power down than the gen 4 plus has a better drag co efficient so win win!
 
In what way is the Gen 5 better at putting the power down than the Gen 4?
 
Dunno I was just told its better, maybe as its a lighter car than the previous gen the haldex works better. But I can see your dying to tell me how it isn't so go on.
 
Any idea on how your tune would stack up with a DP/FMIC/intake setup?
 
audi upgrades
Unless it's a tuning box, any remap such as Unicorn, Revo, GoAPR would trigger a TD1
 
Briefly:

When you take your car into Audi, and if they hook it up to VAS/ODIS for a scan, this communicates with Audi AG.

If the contents of the software in a ECU differs from the software currently in the car (checksum) - it will flag a TD1 code.

There are any number of reasons why the contents of the software might be different, eg: dealer performs a software update without live ODIS connection etc.

This does not automatically say warranty void - discussions will take place between you, dealer, Audi UK, Audi AG etc.

The likelyhood is, if you mapped your engine ECU for more power, then say the quattro propshaft UJ's fail, they may refuse to honour the warranty as the extra power would be seen as a contributory factor to the failure. But if an unrelated component failed (eg: MMI) then I can't see them refusing to honour the MMI warranty as it's fairly unrelated.

More on TD1:

Note that although a tuning-box isn't likely to flag a TD1 - it wouldn't be correct to say that it was undetectable, even after removal. A determined engineer could always find traces and anomalies associated with extra boost, proving it would be another matter.

Back to the different software in the ECU - if you then flashed the original software back into the ECU prior to taking it into the dealer, the original checksum would match, so no TD1 flag. Flash counter would be a different matter of course, reset?

This whole thing with tuning boxes not triggering a TD1 isn't guaranteed at all. The ECU is like a black box these days it even measure turbine speed along with everything else. Does a tuning box not alter turbine speed? Yes it does so sure as damn it the ECU is storing that fact.

If you plug it into a dealers ODIS it may not trigger a TD1 to begin with but if they for whatever reason dig a little deaper its there stored in the ECU's memory, theres no getting around that unless a you do a full stock reflash and the checksum is the same as far as im aware.
 
Turbine speed? Where is the sensor for that, not seen info that the turbos are equipped with that. Do you have any available info on the subject.
 
Rick, great results :)

You mentioned on another thread, end user ability to remap by early next year. Is this based on the kit CMD Flashtec are developing (My Personal Flasher) ? . I really want to get the car remapped but am holding out until I can put the car back to a stock remap myself for servicing/warranty issues.
 
Lets not take this off topic its unfair on unicorn. That's just what I was told by a reputable source.
 
Rick,

Do you have to spoof the torque figure the ECU reports to the TCM ?

Cheers.
 
Brilliant results Rick once mine arrives and you have the flasher I will be in touch.
360 BHP and 518NM I am well happy with that, that gearbox can cope with a lot of torque.
 
Had a Golf R on the dyno today, even better results!

That is quite a difference, I wonder what could account for that, seeing as they share the same engine and platform.
 
I am not sure. For one i is a manual. There are likely differences in the engine, there were in the previous generation. This car is less than two weeks old, but has done 2000 hard miles, it might just have loosened up more than S3

Rick
 
I wonder if the DSG box on the S3 is limiting the torque..?
 
No, it's not. That's known as torque shedding, it's actually easier on this ECU to alter the reported torque than the Bosh ECU's. Need a few more of each on dyno to see if there is a pattern.
