UK Chip Tuning

UK TUNING software can improve the performance of your car, which is currently limited by compromises. During manufacture, allowances are made for the worst grade of fuels and going many miles without proper servicing. If you are prepared to service your car on time, our chip tuning can give you a better drive.

We can improve the performance of most modern cars, including turbo and supercharged vehicles. Your car will have a sharper reaction, be more responsive and get more miles-per-gallon. Each program is customized for your vehicle and driving habits.

The new software 'adapts' or learns as you drive over several days to improve your horsepower, torque and mileage by 10 to 45%. 

How do we do it?

The program for any engine is held in the memory on an ECU chip. This program can be read by a computer, but can't normally be altered. UK Tuning can reprogram the ECU chip, and our objective is to make it better than the original.

Torque is the fundamental item for improvement, and increases are usually in the order of 35% on normal turbo cars. The engine is read through the OBD socket with diagnostic equipment to optimize all maps in the car.

Chip Tuning and Remapping

Remapping and "Chip tuning" as it is commonly known, is the art of modifying the standard ECU software, which is stored in the factory engine management system, otherwise known as the ECU. In order to increase the power-output of the engine, it is important to change the certain parameters, to give the engine will have the up-most efficiency in burning fuel, required for power and economy. An increase in power output of about 25-50% can be achieved, combined with a smoke-free vehicle and improved fuel economy of about 5-10%.

What is involved?

Normally the original software in the ECU is read first and stored as a file. This file is then modified and then programmed back into the ECU, overwriting the original software. Only the maps essential for improving the performance of the engine are altered. Most of the time the software is read and programmed to and from the ECU via the OBDII diagnostics port, so there are no physical changes at all. Even if the ECU has to be removed from the car for access, it's normally a non-invasive process of reprogramming the ecu.

How does remapping and chip tuning compare to a tuning box for a diesel engine?

Tuning boxes are add on devices that work by intercepting the signals between the ECU and the sensors and fuel system in the engine. Some tuning boxes intercept the sensor signals fooling the ECU into thinking that the engine is doing something different to what it actually is, thus making the ECU add more fuel. Other tuning boxes work by intercepting the output signals from the ECU and thus modifying the fuel control. Either way, a tuning box will only increase the amount of fuel that is added. Furthermore, the tuning box is always fighting the ECU. The ECU will to some extent try to compensate for the increase in fuel that is caused by the tuning box. This is especially true of the latest Euro IV engines with very tight emission controls. The end result is often inconsistent performance, and sometimes no improvement in performance at all.

UKTUNING DOES NOT RECOMMEND TUNING BOXES WE RECOMMEND REMAPPING

A remap on the other hand actually improves the engine and emissions control. A "remap" is simply a rewrite of the software in the engine computer. Unlike the tuning box which only alters the amount of fuel, the ECU remap alters the turbo boost pressure, fuel injector duration, fuel timing, fuel pressure, and many other maps, all of which can be optimised to give substantial increases in power and torque. With new engines, the ECU remap is the only way to improve performance because the ECU is too sensitive for a tuning box to successfully alter the behaviour of the fuel system without the ECU compensating for it.

We guarantee that our ECU upgrades will outperform any diesel tuning box currently available in terms of performance and emissions!
