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, 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 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.
