Frequently Asked Questions


Improveed diesel performance

Q) Why is a DTUK Diesel Tuning system better than a 'chip' or remap?

A) We are often asked which tuning option is 'best' and there simply isn't a one-fits-all answer to the question.

Professional, reputable, remaps certainly have their place, especially on a vehicle that has or will have an extensively modified engine. A remap will tailor a vehicle to an uprated turbo, FMIC, etc, far more effectively than a tuning system.

For the average driver who is looking for a safe upgrade that will provide power, economy and enhanced drivability, a DTUK tuning system is the way forward.

The majority of our systems can be fitted by the average customer in less than half an hour, many in 5-10 minutes. All come with full colour fitting instructions and first class telephone customer support. Be very wary of anyone who can 'flash' a remap to your car in that period of time as it is most likely a generic map downloaded off the internet and loaded from their laptop.

All our systems offer a range of adjustability not available with a remap or chip. As each vehicle is built to a manufacturing tolerance, no two are the same. The same is true of each driver. As such, adjustability is required so that the customer can tailor the system to their vehicle and driving style.

Many engines are shared between manufacturers, as are components and technologies. As such, most DTUK tuning systems are transferrable between a variety of vehicles, often only requiring a software change (free to existing customers) or a change of loom (charged at a trade price to existing customers). Alternatively, if nothing can be done to transfer an existing system to a new application, an existing customer can purchase a suitable system at a trade price.

DTUK tuning systems are well known across internet forums and popular auction sites. As such they command a healthy resale value should you choose to sell the system on when you change vehicle, whereas a remap or soldered chip would stay with the vehicle and your investment would be lost.

A remap or chip can also cause you issues should your vehicle visit a garage, dealership or be subject to a warranty repair or recall. Firstly, It is standard practice in many workshops to automatically perform a full software update on any modern vehicle that goes in for work. This update is highly likely to overwrite any aftermarket software (remap) installed on the vehicle. Secondly, the presence of a remap or the physical alterations (breaking the seal on a factory ECU, etc) required to install a chip will immediately invalidate any manufacturer or aftermarket warranty.

Testing

Q) If the car is capable of safely making this additional power, why does it not do so from the factory?

A) Another very common question that has a few contributing factors to the answer. Modern vehicles are built globally, using manufacturer platforms that are designed to be used in a variety of applications, in a range of diverse environments across the world. If we take, as an example, the popular 2.0 170ps Common Rail engine built by the VAG group. This engine is used in a sporty Seat, a large executive Audi, a, Skoda taxi, a load-lugging Volkswagen Amarok pick-up truck and everything in between - all with the same management software. Because of the global nature of modern vehicles it has to be able to cope with driving through the Sahara Desert and a Norwegian winter fuelled by the lowest quality of diesel you could possibly find in a third-world fuel station. If we remove all those variables and focus on your specific vehicle, being driven in a country that benefits from a mild ambient air temperature and a high quality of diesel we can comfortably take a vehicle to a level that far exceeds the standard, generic set-up whilst staying within the engines tolerances and safety parameters.

Another consideration for certain vehicles is that a lower powered variant is often a restricted variant of the same manufacturers own higher powered engine. If we go back to the VAG group the 2.0 140 Common Rail and 2.0 170 Common Rail are only differentiated by the software installed by the manufacturer.

Q) Can a DTUK tuning system damage my engine or its ancillaries?

A) DTUK tuning systems are designed and manufactured by DTE Systems of Germany to exacting standards and meet with TüV approval, probably the most stringent testing standard in the world. All systems are developed to work within the confines of the vehicle manufacturers safety parameters. We have never had, to our knowledge, an incident where our unit has been responsible for any engine or engine related problem. Virtually, all incidents reported to us at DTUK can be attributed to customer misfitment. For additional peace of mind all systems are shipped with a, non-transferable, 3 year warranty Diesel Tuning UK Warranty.

Q) Will I achieve the figures that are published?

A) The majority of our figures are based on data gained from rolling road testing undertaken here in the UK or in Germany. As each vehicle is different, due to manufacturing tolerances, state of repair, time since service, etc, we cannot guarantee figures for horsepower or economy. Anyone who does offer that guarantee is making a promise they simply can't keep.

Back to top ^

Q) How can I have increased power and economy, surely that is having your cake and eat it?

A) Efficiency and economy is governed by how hard the vehicle has to work to move itself down the road. If you have more horsepower and more torque, the vehicle is able to get up to speed with less effort, tow more easily, cruise in higher gears, etc, which all leads to improved economy. A DTUK tuning system is designed to optimise the vehicles torque level and deliver the power when and where you need it. 15% increases in economy are common and backed up by our many, many customer testimonials.

Q) How do I know that I am getting the best from my DTUK system? What setting should I use?

A) We always advise testing the various settings of a DTUK system and this is the only way to get the best from the system. A session on a rolling road can tell you which setting gets the most power on your particular car. Miles of back to back testing can tell you which setting gets the best economy on your particular car. Friendly internet forum users can tell you which setting they like on their own personal car. But, no one except you can tell you which setting YOU like to use. Our happiest customers are always those who take the time to explore the various options from their chosen system.

Q) How easy is it to adjust the systems between the various settings?

A) We have a variety of systems on the market, depending on installation, which are adjusted in one of two ways. In each instance they system will have a protective window or cover that has to be removed using a T10 Torx bit - if you don't have one just let us know at time of ordering and we will happily include one with your order free of charge. The two adjustment types are either a simple dial that adjusts in increments or a series of jumpers and pins. Adjustment instructions are included as part of the fitting guide.

Q) How easy is it to remove the vehicle to factory standard?

A) Very simple, DTUK tuning systems are shipped with a blanking plug (system dependant) which can quickly and easily be attached to the loom in place of the tuning box in only a couple of minutes, returning the vehicle to standard performance. To go completely to standard simply remove the loom in a reversal of fitting, leaving no trace of our system.

Q) Do you offer a bespoke service?

A) Yes, but only at our HQ in County Durham. We will happily work with any customer using one of our multimap systems, by appointment, to optimise their system and their preferred software.

Q) Do I need to tell my insurance company?

A) Yes, you should notify your insurance company of any modification that alters a car from factory standard. Many insurance companies are aware of our systems and the positive impacts they can have on your vehicle. Please feel free to ask us for recommended insurance companies.

Q) What if I have a problem with my DTUK tuning system?

A) Simply select one of the options on our Contact Us page to get in touch so that we can discuss your problem and take the necessary steps to rectify it for you.

Q) Who can I contact about a DTUK tuning system that I have purchased second-hand?

A) Unfortunately, we cannot offer warranty or aftersales support on second hand systems. Far too many unscrupulous people are misadvertising our systems on the internet in order to sell them at a higher price. We regular encounter systems purposely missold for an incorrect application, other companies systems passed off as ours, damaged or outdated systems being sold on with non-existent warranties and/or forged paperwork.

Back to top ^

Q) Can I part-exchange an old system against a new DTUK tuning system?

A) No, we do not accept part-exchanges against new systems. This simply does not represent the best value for you, our valued customer. As an existing customer you can purchase a new system from us at a trade price and can sell your old system online for more than we can offer you for an exchange.

Back to top ^

Q) I am unsure exactly which engine variant I have, how can I tell?

A) In many cases, your logbook (V5) document that came with your car will give you the information you require. Alternatively, give us a call with your registration number and we will do the rest.

Q) My vehicle doesn't appear to be listed, do you have a DTUK tuning system for it?

A) It is virtually impossible to maintain a comprehensive, up to date, listing. Get in touch through the Contact Us page and we will happily check your application.

Back to top ^

Q) Can I combine your system with a remap/chip?

A) A DTUK tuning system, a chip and a remap are all designed to achieve similar end results in different ways. It is not recommended to combine them.

Back to top ^

Q) I have changed a setting and now have an Engine Management Light (EML), what do I do?

A) The EML is the vehicles way of telling you that you have been a little greedy and that it is not comfortable with the new setting. Simply switch the box to a different setting and try again.

Q) Do you sell to international customers?

A) Yes, we certainly do. International shipping options are available at checkout and VAT free prices are available for relevant countries.

Back to top ^

Q) Can the vehicle manufacturer detect a tuning module?

A) There have been many instances of manufacturers detecting "remapped" software within a vehicle's ECU (Electronic Control Unit). However, we do not remap the ECU so this style of detection does not affect our products. We work downstream of the ECU. We are not aware of a single instance of a manufacturer detecting a tuning module if the tuning module has been fully removed from the vehicle prior to it going in to the dealership for maintenance. However, the fact remains that vehicle manufacturers will continue to enhance and upgrade their software so we cannot state unequivocally what the future will bring. When purchasing any form of tuning the purchaser assumes all inherent risk that those modifications may bring. No guarantee is offered with regards to your original manufacturer's warranty.

Q) My question isn't listed here, what can I do?

A) Simply get in touch through our Contact Us page or leave an online/offline message in our chat window.

Q) Why are your kits more expensive than those available cheaply on auction sites?

A) Probably the most discussed points when it comes to diesel tuning. Here is a recent blog article drawn entirely from the experiences of one of our customers which led to a feature in a popular car magazine - Why Tuning Systems have a bad name
