So why don't vehicle manufacturers tune their vehicles?
The most common of all tuning questions. It is not complicated but there are a few answers to this question, some more obvious than others.
Vehicle manufacturers are in a tough position here, they have to build one vehicle for all drivers – it’s a bit like a nice suit off the shelf; it fits well, it looks smart, but it can’t be custom tailored for the end customer. Tuning is just the same – if you own a fleet of vans you may want a speed limiter or rev limiter added to help save your fuel, yet another customer may want a little more power to help with towing or heavy payloads. These sorts of changes can only be made once the vehicle is built and the customer needs something other than ‘off the shelf.’
Fuel quality – we are often asked to tune for different fuel quality, either higher or lower. Once an owner knows where his vehicle will be used and what it will be used for we can adapt the tuning for environmental, altitude and fuel quality.
And surprisingly, many manufacturers do offer ECU remapping services – any showroom these days will be full of eco-tuned vehicles, often sporting a ‘blue’ badge just like our BlueOtimize tuning. With our tuning though, you don’t need a new vehicle to benefit from economy tuning.
In addition, many manufacturers offer power and performance tuning upgrades too or offer the same engine in a range of vehicles offering different power levels. This enables customers a choice, taking account of tax banding, insurance, performance, price and economy. In most cases though the choice is controlled with software just like our tuning, but with Viezu you don’t have to decide what you want from new in the showroom, we can tailor your vehicle to your needs whenever you want.
Will a remap invalidate my car's warranty?
No. A remap or any aftermarket work cannot and will not automatically invalidate a vehicle’s warranty. It’s a misconception that it will, and sometimes those that know are not always clear about this fact. It’s very common for fleet users and companies to fit a speed limiter to their vehicles. Some will use us to do this work, while other drivers may want to fit a tow-bar or upgraded sound system to their vehicle. These are common fitments, but they are aftermarket changes just like a remap – your tow-bar does not invalidate your warranty so why should you remap?
However, manufacturers of course have the right to investigate and possibly reject a warranty claim if the failure is directly related to and caused by the tuning (remember not all tuning is the same quality as Viezu). Therefore, for your total peace of mind, all Viezu tuning work is insured and guaranteed. If our tuning causes a failure inside or outside of the warranty period you are covered. It’s exactly why you should choose Viezu for all your tuning work – only Viezu dealers have this depth of cover and your dealer will be happy to show you and talk through the Viezu tuning insurance policy. We say this with confidence because of the rigorous testing regime all ECU remapping and vehicle tuning files go through, and we even give a lifetime software guarantee too for reinstallation.
Should you lose your tuning files due to dealer actions or parts failure your dealer will be happy to re-install the map onto your car free of charge for as long as you own the vehicle.
Is tuning legal in Europe?
Yes, owners are allowed by law to modify their vehicles, but it should be done responsibly and in accordance with local legislation. The EU Directive 2010/48/EU does stipulate that vehicle owners should not modify or alter their vehicles in a way that the emissions are increased. Viezu treats tuning very seriously – in these times of environmental scrutiny, we believe the tuning industry should be both responsible and transparent in the work being carried out.
At Viezu, not only do we measure and test our tuning to Euro 6 MOT Emission Standards, we exceed these standards testing for both Nox and Sox too. Our tuning has been independently tested on a number of occasions, and found to have no negative impact on emissions. We have also opened our testing and development work and have been inspected by the DoT (Department of Transport). We are proud of our work and the research and development we carry out.
Viezu is able to offer test and measurement services, please contact us to find out more.
Should I tell my insurance company?
Whilst the upgrade in many cases is undetectable, the responsible and correct answer to this question has to be “yes”, your insurance company should be notified of any modifications including tuning. However, the good news is many insurance companies do not penalise you for upgrades of this nature, particularly if you’re tuning for increased fuel economy.
Adrian Flux is one such company.
Will my fuel consumption go up after an upgrade?
No, in fact, quite the opposite. Even on a performance tune, if you continue to drive the car in the same way as you did before the upgrade, your fuel consumption will probably improve. Of course, if you have a track day motorsport tuning map installed on the car, and you are driving the car under the conditions in which full-on motorsport tuning is intended, you’re likely to find a slightly reduced MPG figure. In just about all other cases though Viezu tuning will improve your vehicle’s fuel economy.
Economy tuning can have a dramatic effect on fuel consumption with considerable improvements being achieved along with huge money savings on fuel. All Viezu fuel economy tuning has a money-back promise – if you are not delighted you don’t pay for the tuning.
Will the life span of my engine be reduced?
No, not at all if you use a Viezu dealer. Sadly some engines can be over-tuned, ‘stressing’ the engine, transmission, cooling systems, brakes, etc, and reducing the life span and reliability of the car. This is why it’s so important to choose the best. Choose Viezu – the research and development we carry out to ensure all our tuning is of the very highest standard possible.
We take great care to ensure that all of our modifications have no detrimental effect on your car. In a lot of cases, the economy tune actually helps to extend the life of components, such as the clutch and gearbox, by making the delivery of the power far less aggressive and smoothing the overall drive of the vehicle.
Products and services offered by VIP Design, Paramount Performance Ltd, and Viezu Technologies Ltd are covered under our guarantee when used correctly in legal public highway use. Specifically, we can’t support, or warrant vehicles, products, or services used in motorsport, track-day, competition, off-road, or rally conditions. Vehicle owners who undertake such practices must accept all implications of extreme vehicle use.
Are plug-and-play re-maps and files sold on eBay any good?
There are a number of basic power upgrades available in a plug-and-play format or are downloadable from the web. Whilst some of these items can offer slight increases in power, they operate by merely adjusting a specified signal within the ECU by a set tolerance. It’s impossible to compare these inferior upgrades with a full rolling road re-map which measures and adjusts hundreds of signals and data files within the ECU.
We advise that these generic files and unsupported devices for sale on the web should be avoided at all costs. We’ve seen too many customers come to us after a bad experience – and there was no one else to turn to either. We’re always happy to advise on your tuning needs.
£5 million insurance - that seems quite a lot?
Yes, that’s right, Viezu is insured not only for public liability but also for the act of remap file writing and tuning to the value of £ 5 million GBP. “Why such a high value?” Viezu offers tuning solutions to some of the world’s largest vehicle fleets, some with over 40,000 vehicles, we also offer support to the world’s most reputable tuning and race teams with many hundreds and thousands of pounds invested in any one single vehicle.
Our technical team offers support to over 650 dealers across 64 different countries and we supply over 5000 tuning files per month.
As a Viezu customer, you can be totally confident that nothing is left to chance, especially our insurance. If you have any queries please feel free to ask for a copy of our insurance and quality policies at any time.
Can I remove my DPF, PPF or Catalytic Converters with tuning and / or and exhaust system ?
De-cat pipes, DPF, PPF and OPF delete exhaust systems and the associated tuning is possible. However, any tuning and exhaust system which removes any part of a vehicle’s emission system may not be legal in many countries, including the UK and the EU. As such these systems and services are sold for off-road and motorsport use only. It is vital you check the legislation where you and your vehicle are based before you fit and use these systems on any road-going vehicle.
