This was the car I was refering to:

I suggest that anyone doubting, or has preconceptions on how the tuning boxes supplied by dtuk operate, that they talk to Andrew first @ABYSS before making a judgement based upon "they're all the same". As I stated he is a site sponsor and will be happy to discuss their tuning boxes his company supplies interacts with the engine and the lasting effect it will have. Those who have spoken to him, with an open mind and without preconceptions, would be then reassured. I had the same misgivings, largely based upon inaccuracies perpetrated on different forums. Having owned different cars, with remaps and with tuning boxes I can state that if you go with a professional supplier who thoroughly tests their products then there shouldn't be any issues. However, as the op has discovered even remaps can produce the wrong results. There are plenty of generic remaps that can be obtained that then are used by, so called, professional remappers.

There is no doubt, if you wish to spend the money, then a custom remap matched to the characteristics of your engine and tested on a dyno is a superior product. But the decision is up to the owner.

We have this debate everytime I mention tuning boxes, yes they are not all the same, yes, just like some who advertise remaps, there are duff ones out there. DTUK are not one of them as many, many, owners will testify here in this forum..

However it is in my experience that the tuning box cannot overfuel engines because the ECU, and sensors, prevents that from taking place. No scientific evidence was provided yet and it seems also the op did not bother to discuss his findings with the supplier as different maps can also be supplied. I have tried two so far and each had different power and torque characteristics. Which, perhaps, also proves its not just throwing more fuel at the engine. The fact that a correct box can also change when the power and torque is delivered and change the delivery over the rpm range also suggests they are more sophisticated than what is being assumed by some..

I've tuned many cars and its misconception that a dyno is needed for a custom tune. Put it this way when driving on the road the air flow you can get can rarely be matched by a dyno fan. This means you run higher temp's on the dyno, this now has a big impact intake and exhaust gas temp's. When egt's go up the ECU pulls fuel (as long as the "tuner" hasn't disabled EGT protection) therefore shows less power.
High power cars can shows this more as air flow becomes more important.
I've had cars that make 107mg worth of fuel on the road and then on the dyno pull only 94mg.

Anyway this is off topic. If tuning box fits your needs then that great Im sure they have a market.

I've had a look on their website for my two TDI's , one is fine , perfectly realistic , safe figures .

The other is miles out on torque claiming 100 Nm whereas the average Stage 1 remapping increase claim is 50 Nm , Racechip tuning box claim is 120 Nm !!

Absolutely not safely possible on a realistic dyno with a dpf still in place .

Even harder to attain given the injector recal to older reliable magnetic solenoid injectors from the more optimal Piezo .

This can often see cars making 30 BHP less and torque down from stock on an accurate dyno .
 
Convo slightly got heated.
Sorry @bobby singh to drag you in to it.
Hope op will find the answer he was after

Of course the issue with remaps, and why many are steered towards good tuning boxes, is the matter of TD1 flagged up and the warranty. Of course many, such as my vehicle, are older than three years, so unless an extended warranty is taken out owners are free to do whatever they like. There has been unsubstantiated claims that tuning boxes can now also be be detected raising a TB1. Unfortunately though these claims have never once have been proven and no one in this forum has had a single tuning box detected and neither have the tuning box suppliers returned vehicles...

As I stated, any concerns then speak to them, they do not just sell a product but they also test them throughly on many of the vehicles...

Perhaps my eyes are failing but I could not see any B9 A4's listed on their site, plus we know that the anti tamper proof ECU on the S4 makes it very difficult to remap, according to APR...
 
I have spoken to unicorn since it was advised, I hadn't done this previously as stated above the b9 doesnt show on their website however, it has been confirmed that they can map the a4 b9, didnt ask about the s4 though so maybe worth asking about that separately.

DMS who mapped my car will come anywhere in the country to remove my map and put the car back to stock if the car needs to go back to the Audi dealership for anything. They will then put the map back on once you have the car back. That service is unlimited for 3 years.

Even if the map is put back to standard it will still show on the log that the parameters have been changed

No need as it's mapped .

Would be interesting to see a dyno before and after showing 600Nm !!

Not possible mate , on a accurate dyno with printouts I've seen these make as low as 418 , 428 , 430 , 452 and 455 Nm .
So you can see my point about a box getting it to a real 600Nm .

For what it's worth , a whilst being serviced software ECU update would wipe over it anyway , the most simplest cheapest , and easiest way to give a car a boot up the **** .

Rick is pretty much always at the front of the tuning game when it comes to VAG, BMW Porsche cars. He has the latest tools and more so knows exactly what he is doing. Difficult to keep up with all the new cars and models coming out to keep the website upto date.

Hi cuke2u had my 190 tfsi now 2 years and have ordered the dtuk tuning box and pedal box. in your opinion of having these fof a while now which settings would you suggest offer the best overall use for everyday driving on both box and pedal. cheers
 
Hi, I might have a different map than the one you have as I was offered, and I installed, a custom map about a year ago. It is quite an aggressive one in sport mode and makes life very interesting if the full performance is utilised. Have you the bluetooth version of the tuning box? I also don't have the pedal box so that also might alter the settings...

its just the standard non bluetooth version ahh i thought you had the pedal box aswell. if anyone out there has the pedal box can you give me an impression of the ideal setting cheers.
 
There is no need to balance fuel and air on a diesel engine - the car doesn't. Unlike petrol cars that run on a stoichiometric ratio, diesel engines run a sizeable excess of air under all conditions.

On my 2013 Golf GTD, I got a TDI tuning box, it was awful. Brutal and crude power delivery due to massive and disproportionate fuel delivery. - put your foot down and you'd induce wheels pin in 3rd at 60mph. Their resolution was to reduce the power so much that it was pretty ineffective. It wasn't the power that was an issue, just the crude way it was delivered - regens were happening way too often too.

Tried DTUK a few month later and the difference was night and day. Very smooth delivery of power - like stock on steroids. The car pulled in 6th like stock did in 4th. The difference was very noticeable 184ps to a reported 240ps, it was believable that it was up there.

Regen frequency with the DTUK box on was about half that of stock.

DTUK is my recommendation.

But still get before and after dynos to back up the 'claims' , from what I've seen different box manufactures get different results on different cars , some don't get any results at all or worse.
 
Depends whether you want to see pure numbers as well as feel the difference. It's an unnecessary expense for most to do 2 dyno runs, especially when getting a box via mail order rather than visiting a tuner that has a Dyno on site.

When power and torque are touted for a 20-25% increase, the difference should be very noticeable, even if you can't quantify it exactly.

Thanks for the input yes its because there are many on here that have given good reviews about dtuk that I have chosen them. Looking forward to installing both especially the pedal box as the lag from pulling away from a stop is a pain.

A TCU tune sweetens things up a bit as well and I feel, not proven by anything other than my butt dyno, that it tended to deal with the torque delivery better. Still easy to spin up the wheels when pulling away from stationary, but then the car does that at the stock setting without the box anyway...
 
Right both dtuk box and pedal now installed extra power and torque are definitely noticeable but the pedal box is just great it has totally got rid of the delay when first pulling away. i found sport and race a bit too lively so settled with city mode best for me. :racer:

That video made me laugh.

He makes out that it is such a chore to connect one of the other tuning boxes up, and it's only half way through that he reveals his ulterior motive of selling his own tuning box.

He then raves about the voltage modifications can only do so much because the ECU limits torque above a certain point...surely that's a good thing? It's a safety feature for longevity, he says so himself, then he says how his box can up the ECU's torque limit to get more power...surely that's a bad thing because you're compromising the safety limits set by the manufacturer?

Whatever the outcome, tuning boxes work and the results are very noticeable for output, some do it in a smoother and more controlled way than others.

However, the mpg gains quoted are ********. If you're expending more fuel, your mpg will go down. If you're expending more fuel than the car thinks you are using, the MFD is going to post a higher mpg value, but the truth will be when you fill up just as often. When you've got 190+ hp on ta though, you're only going to spend a small portion of your time getting up to speed, then you're going to be using a fraction of your potential output.

I have used a stretch of road to compare rolling performance with my cars. There's a slip-road onto a dual carriageway near home. I pass a certain sign at 20mph then hoof it and see what the car's doing when I pass a second sign (when the road is very quiet). Here's what my cars did:-

2005 MK5 Golf 140TDI PD = 70mph
2007 MK5 Golf 170TDI PD = 78mph
2009 Scirocco 140TDI CR = 76 mph
2011 Scirocco 170TDI CR = 80mph
2013 MK7 Golf GTD (184ps) = 82mph
2013 MK7 Golf GTD (184ps) with DTUK box= 87mph
2015 MK7 Golf R (300ps) = 94mph
2018 AW Polo GTI+ (200ps EA888 3B) = 83mph

You can see the difference that DTUK box made to my GTD. Not sure i'd have one now, seeing as they're theoretically detectable now, which would bin your warranty. Back in 2013 they were considered untraceable.
 
Nice results, only theoretically detectable as you say and possibly only if the dealership has a sniff something is amiss. There is a letter doing some rounds supposedly from a dealership dated 2013 that has the wording 'TB1'. Yet no-one else has had this and DTUK haven't had one issue in returning their test vehicles to Audi..

If I could be sure that the boxes were 100% undetectable (as was assumed the case prior to around late 2015), i'd have another one tomorrow (insurance willing). As you can see from my list, i've always been a fan of TDIs, they are definitely built to last. It's hard to quantify whether anyone would have any issues with one of these boxes being detected because the TDI drivetrain seems so reliable.

I'm a firm believer that fitting a box won't be absolutely obvious when you take your car in for routine servicing, and if they are detectable, the dealership or VW GmbH centrally would have to look hard for signs of adulteration of signals, on a manual gearbox at least - not sure whether having a DSG box allows better detection of increased torque output significantly above expectations.

With that in mind, I don't think VAG go looking for these unless there's a significant drivetrain or fuel system failure that someone's looking to get sorted under warranty.

I visited DTUK on quite a few occasions - they're semi-local to me and I was invited by Andrew to trial the (then) new "Trevor" box out for them and keep it as a free upgrade. They're a great bunch of lads, and as I said, the DTUK box transformed my Golf GTD without increasing the mpg appreciably and the frequency of DPF regens was less than stock after the initial adjustment of about an hour's running. When I got my Golf R, I passed my box on to my Dad for his GTD and it ran well for about 90k miles. His car went in for a post-dieselgate "correction" and the car was never quite right since, VW made it worse and after that ECU update, the car didn't tolerate the DTUK box well after that so my Dad took it off. Most likely it needed an update back at DTUK. Once I had the Golf R, I didn't consider getting a box for it because it was manual and the manual stock clutch used on the Golf GTI and R is *****. Mine slipped on me a few times on cold days, and pretty much everyone on the Golf GTI forum who's had their GTI mapped or boxed has knackered their clutch within a short space of time.

If I could be 100% assured that these boxes are still undetectable in the case of my engine or DSG box failing under warranty, i'd be on the phone to my insurance company right now and popping down to DTUK.
