What is Chip tuning?

Chiptuning is the common name for the process of optimizing vehicle engine management software by changing the parameters. This results in improved performance and/or lower fuel consumption, and the addition or removal of functions. Today the term ‘chip tuning’ is used to describe the process of modifying that software. There is no longer addition of special electronic components (chips), but instead the ECU’s (Engine Control Unit) software itself is modified and then written back into the vehicle ECU. That’s why we prefer the term ECU remapping.

Process of ECU optimisation / chiptuning

the vehicle ECU

This is done by specialised tools by reading the software over an OBD2 diagnostic port or, directly from ECU itself. It’s done either by connecting to ECU port via specific connector, or by connecting to the ECU port pins directly or, in rare cases, by opening ECU and connecting directly to the processor and special contact points.

of the software

After reading and uploading the original file to our system, our experienced in-house developers modify the settings and map the values needed to achieve the desired results for each vehicle individually. Once the software optimisation is complete, it is saved in the database together with the original file, and delivered to the customer.

Writing the software to the ECU

Modified software is developed specific for the exact vehicle model, year, engine, ECU hardware and software version including all specific options and can be written into the ECU in the same way as it was read. After the writing of the optimised software, your vehicle instantly benefits from the improved software and performance.

What are the Chip tuning


The main advantage is releasing the full potential of your engine and vehicle itself, which has been tamed from the factory to achieve emissions and fuel consumption norms for different markets, or to position vehicle in the lower price bracket due to marketing decisions. Further, it is a completely reversible if you ever want to go back to the original stock form.

Is chiptuning


Tuning or ECU remapping is the cheapest way of modifying vehicle software and thus altering performance, characteristics and functions of the vehicle. The price depends on several factors including workshop hours, professional tool & licence expenses, the remap development price for your specific ECU and desired options, and is set by each dealer individually for their market.

For the exact price it is best to contact one of our dealers closest to you.
