CHIP Tuning. How does it work?
To understand CHIP Tuning per se, you should understand the function of today’s motors in rough detail.
Since the 1990s, control units are built into the engines. Initially these control units only had simple functions. Thus, originally only the information on the fuel quantity and the injection time was transmitted by signal to the nozzles. Today the situation is of course different. The rapid growth of EDP did not leave the motor vehicle unaffected. Highly-integrated switching circuits, SMD assemblies, light conductor technology, ABS & ESP systems, solar energy and safety systems – they are all the everyday components of newer automobiles.
Greater and greater significance is also given to the engine control unit in this regard. The engine control unit today is in charge of all engine management. It controls and regulates all of the important functions of a motor. Here the application parameters (load state, external temperature, air quality, air density, motor, oil and cooling average temperature) can be analysed and assessed depending on the driving data (RPM, loading pressure, speed). The engine control unit processes all of these data “just in time” in order to set the optimal operating condition for the engine.
The data in a program and a database are processed in the engine control unit depending on these various parameters (provided by probes and sensors). Thus, the load pressure, injection quantity and ignition time are passed on to the engine.
This program or the database are located in one or more chips in the control unit. The specialist calls the optimisation of this “software” CHIP tuning. All engine maps, data framework and principal characteristics of the control unit are optimised using the most cutting-edge developer tools by our engineers and technicians depending on the load and speed in terms of the torque progression, performance increase and consumption.
Better performance and a higher torque with minimal fuel consumption is achieved through CHIP TUNING. The increases in performance and torque are between 20 – 40 % for turbo engines. 10 - 20% are possible with non-loaded engines. As a whole, the engines become more lively and more powerful, which becomes evident through better acceleration, agility and maximum speed. The service life as well as the daily capability are affected just as little by the customised SKN CHIP tuning as a series production engine.
