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.

Questions about your vehicle’s factory warranty? Most vehicle manufacturers will not endorse any performance software or hardware performance upgrades on a vehicle that still has it’s original factory warranty and or motorplan intact. It is therefor important that customers understand that manufacturer’s can cancel a vehicle’s warranty or motorplan, should they pick up a mechanical or electrical issue specifically related to the software or hardware modification(s). Wulfchiptegnik™ will always advise their customers to first return a vehicle to stock, before they vehicle is taken in for any servicing or warranty claims at the manufacturer. Wulfchiptegnik™ software has been developed specifically for South African conditions, fuel octanes and have been tried and tested before being released to market. All modifications will be subject to the customer signing an indemnity form.
