Wulfchiptegnik™ engineers have developed software for most mainstream vehicles that can easily be uploaded to your vehicle’s ECU via the OBD-II port.
The engine is controlled by a micro computer commonly called an Engine Control Unit (ECU). The ECU controls different variables on the engine like ignition timing and the amount of fuel injected into the engine, taking into account certain variables such as engine temperature, engine revolutions (RPM), air temperature, exhaust gas temperature (EGT), throttle position ect. All this is communicated via many different sensors connected to the engine. The ECU reads out certain pre-programmed values in the map for ignition and injection timing values and will compensate where needed for different engine loads and temperatures, in which the best available amount of fuel and optimum ignition timing can be calculated from these maps in conjunction with each different sensor value. These are the exact maps that gets specifically adjusted, tuned and optimised for performance or economy by our engineers with our specialised software via a direct cable connection to the OBD-II (On Board Diagnostic) port on your vehicle.
