Today's modern cars are computer controlled by an ECU or "engine control unit”. The ECU contains the software that controls the fuel delivery and ignition timing. Chip tuning optimises or rewrites these programs in the computer. This changes the fuel delivery maps and boost pressure of the turbocharger. As a result the engine will run more efficiently and have increased horsepower and torque figures.
Turbocharged vehicles will achieve up to 20 to 40 % increase in horsepower and a remarkably stronger torque levels. In a normal petrol engine (no turbocharger) the performance increase will be between 6% and 12%. The acceleration and final speed is recognizably improved along with less fuel consumption, if same driving conditions are assumed. Overall the engine is more alive and powerful. In the control unit are also maps programmed to direct the fuel injection depending upon load and engine speed.
About DSG Gearbox Tuning
DSG Gearbox Tuning consists of modifying the software on the gearbox ECU to allow us to make smoother and faster gear changes. Gear changes can be made so that we can achieve up to 50% quicker changes. We can also activate and move Launch Control limit to 4200rpm for better launching when required. This software is currently only available for Volkswagen, Audi, Skoda & Seat DSG fitted vehicles.
Why does'nt the manufacturer do this from factory?
The engine management program is stored on a Chip (EPROM) and can basically not be changed. The manufacturer must develop his vehicles for a world wide market and must take into account many different circumstances. These are e.g. fuel quality, emission regulations, frequency of service and also financial
reasons such as insurance.
Does tuning shorten the life of the engine?
That depends on the modification of tuning. If no limits are exceeded, and if the driving of the customer is "normal", no increase of abrasion can be expected.
Is it possible for my vehicle to be tuned?
Almost all diesel turbo and petrol turbo vehicles as well as some non turbo petrol engines can be tuned. If you require more detailed information on a particular vehicle go to our contact page and fill out your details and we will get back to you as soon as possible.
