1. About These Terms

These terms apply to all services provided by AC ChipTuning (Majke Jevrosime 11, 74480 Modriča, Bosnia and Herzegovina) and to use of this website. By submitting a booking request or bringing a vehicle to our workshop, you confirm that you have read and agreed to these terms.

2. Services

AC ChipTuning provides automotive calibration and diagnostic services including but not limited to:

• ECU remapping (Stage 1, Stage 2)
• Transmission (TCU) calibration
• Diagnostic scanning and fault code analysis
• Dyno measurement and validation
• System solutions (EGR, DPF, AdBlue, Vmax, Start-Stop, Pop & Bang, and related)

All work is carried out in our physical workshop in Modriča. Online file service is available for authorised dealer partners under a separate agreement.

3. Vehicle Condition

The customer is responsible for ensuring the vehicle is in a safe and roadworthy mechanical condition before a service appointment. AC ChipTuning reserves the right to decline or suspend a service if an inspection reveals pre-existing mechanical faults, worn components, or any condition that could make calibration unsafe or unreliable.

If a fault is discovered during service, we will inform the customer before proceeding. Any additional diagnostic or repair work requires separate customer approval.

4. Performance Figures

Any power or torque figures provided (whether in the vehicle catalog, on our website, or during consultation) are indicative only. Actual results depend on the individual vehicle’s condition, ECU hardware version, fuel quality, ambient conditions, and other factors beyond our control. AC ChipTuning does not guarantee specific power outputs.

5. Manufacturer Warranty

ECU calibration and certain system solutions may affect or void the manufacturer’s warranty on your vehicle. It is the customer’s sole responsibility to understand and accept this risk before authorising any work. AC ChipTuning does not accept liability for warranty refusals by manufacturers or dealerships arising from our calibration work.

6. Emissions and Legal Compliance

Some services (including but not limited to EGR delete, DPF delete, and AdBlue solutions) may affect the emissions compliance of the vehicle under local or national law. The customer is solely responsible for understanding the legal requirements applicable to their vehicle in their country of registration and use. AC ChipTuning does not accept liability for fines, failed inspections, or legal consequences resulting from the customer’s use of a modified vehicle.

7. Payment

Payment for workshop services is due upon completion unless otherwise agreed in advance. We accept cash and bank transfer. We do not process card payments online.

8. Cancellations

If you need to cancel or reschedule an appointment, please notify us as early as possible by phone or email. We do not charge cancellation fees for reasonable advance notice.

9. Limitation of Liability

AC ChipTuning is not liable for:

• Indirect or consequential losses arising from the use of a calibrated vehicle
• Losses resulting from pre-existing vehicle faults that were not disclosed before service
• Losses caused by the customer’s failure to follow post-service guidance

Our total liability for any direct loss arising from a service is limited to the amount paid for that service.

10. Governing Law

These terms are governed by the laws of Bosnia and Herzegovina. Any disputes that cannot be resolved by mutual agreement will be subject to the jurisdiction of the competent court in Modriča.

11. Changes to These Terms

We may update these terms from time to time. The revision date is shown at the top of this page. Continued use of our services after a change constitutes acceptance.
