How do tuning boxes work
HOW IT WORKS…
For many years, engines have been controlled by Electronic Control Units (ECU’s) that interact with an ever-increasing range of sensors across the vehicle. These sensors send signals, sometimes thousands per second, to the ECU. The ECU interprets these signals and responds to ensure that the engine is running at optimum efficiency and within set safety parameters at all times. This ensures that the factory defined power is delivered whilst maintaining acceptable levels of emissions and economy.
A DTUK tuning system intercepts these signals between the ECU and engine and then modifies them against a set of parameters that we refine individually for each application. These modified signals will, depending on application, interact with fuel, boost, timing and more to increase torque and horsepower. In the case of the new i-art injections system used by Volvo, our system connects to all 4 injectors. This is due to the fact that this unique injections system uses individual pressure sensors at each injector, rather than a single pressure sensor found on the common rail .The increased power levels available throughout the engines powerband mean that the engine doesn’t have to work as hard which leads to improved economy.

Many customers wonder why modern engines have such vast scope to tune or why a vehicle manufacturer has many seemingly identical vehicles in the range where power output is the only difference.
The simple answer is to generate sales across multiple markets and for multiple uses in the cheapest possible way. It no longer makes financial sense to offer ten different engines when you can have two or three engines each available in a variety of power outputs. These different power outputs are rarely achieved by mechanical changes but rather by adjusting the software. This means that we can replicate those changes for a fraction of what the dealership will charge.
Engines are now a global item meaning that they have to conform to every different strict emission regulation and tax band as well as being able to run in extremes of temperature using poor grade fuels. We can take advantage of that by shipping your DTUK Performance System with software designed to take advantage of your engines true capability and designed to work with your local fuel quality and temperature ranges.
In short, we deliver you what your vehicle is truly capable of.
