ECO Performance Tuning

Content Writing . David Warham


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.
