Frequently Asked Questions

So why don’t vehicle manufactures 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 manufactures 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, its 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 sort 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 manufactures 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 vehicles warranty. It’s a misconception that it will, and sometimes those that know are not always clear about this fact. Its very common for fleet users and companies to fit a speed limiter to their vehicles, some will use us to do this work, other drivers may want to fit a tow-bar, or upgraded sound system to their vehicle, these are common fitments, but they are after market changes just like a remap, your tow-bar does not invalidate your warrant so why should your remap?

However, manufactures of course have the right to investigate and possibly reject a warranty claim if the failure is directly related too 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 chose 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 life-time software guarantee too for re-installation.
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.

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 motor-sport tuning map installed on the car and you are driving the car under the conditions with which full on motor-sport 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 vehicles 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 ensures 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.

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 cost. 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.
