Micro Chiptuning OBD for gasoline engines

Microchip tuning OBD for all petrol engines from 2008

In June 2015, the company Micro-Chiptuning Deutschland presented its newly developed ‘microchip-tuning OBD’, increasing performance for all petrol engines with forced induction. Its technical function is what makes this OBD chip unique. The microchip-tuning OBD system continuously optimises the combustion as you drive.

Micro-Chiptuning Deutschland was the first company to successfully achieve increased performance by improving the adaptation’s values during driving. The chip communicates with the vehicle via the OBD (on-board diagnostics), constantly reading the current engine parameters. Performance is increased by actively optimising the adaptation’s engine map in the engine control unit. This patent-protected invention is what makes this microchip-tuning OBD system so unique. After a lengthy development phase, average performance increases of 5–10% could be established for the test vehicles – in both partial load and full load tests.

The hardware

As stipulated by ISO 15765, all vehicles first registered from 2008 onwards feature a diagnosis interface with CAN bus connection. The performance-enhancing electronics take advantage of this requirement, as well as guaranteeing simple installation and extremely wide availability.

In contrast to conventional options, the OBD chip can be removed at any time and used in another vehicle with this interface. Thanks to this unique feature, this newly developed chip has made its mark on the market. Because we placed great importance on affordable Plug & Play right at the development stage, the chip is incredibly easy to install. The module is installed in just a few simple steps, and is just as easy to uninstall. All you have to do is connect the supplied product to the OBD interface – literally Plug & Play. The OBD chip’s modern SMD board works on the basis of one of the latest Flash microcontrollers with ECAN technology. This hardware forms the basis for perfect communication between the add-on controller and engine control unit.

The software

As the name OBD (on-board diagnostics) implies, the OBD chip communicates with the engine control unit via the vehicle’s diagnostics interface, which is already installed as standard. Increased performance is achieved by targeted positive influencing of the engine control unit’s engine map. This results in optimised combustion, increased engine power and improved responsiveness.

Once the add-on controller (microchip-tuning OBD) has been connected to the diagnostics interface, it permanently communicates with the engine control unit. During this communication, the engine control unit delivers various operating parameters, which the OBD chip then uses as input values for the stored engine maps and threshold values. As you drive, the device has a constant effect on the engine control unit, and is so able to increase engine performance at many operating points. Errors from the engine control unit are normally only notified if they still exist after three drive cycles. This means that wear or defects are not detected promptly. The OBD chip, on the other hand, constantly checks recorded and pending error codes. If an error code is detected, this is immediately notified to the driver by means of an LED, and at the same time all OBD chip operations stop. The OBD chip therefore not only increases performance, but also serves as an early warning system for overdue repairs.
When the engine is switched off, the add-on controller activates its energy saving mode and checks in cycles for engine start-up.
