Chip tuning · ECU repair · Auto diagnostics — Banja Luka
Chip tuning, ECU repair and diagnostics for all European and Asian brands.
WHAT WE DO
Six core services we're known for across the region
EXPERTISE FEW WORKSHOPS IN THE REGION HAVE
Over 15+ years, we've built deep knowledge of every major ECU platform on the market. We don't buy clones — we use original BOSCH, SIEMENS and Magneti Marelli programmers and diagnostic tools. That's the difference between a workshop that guesses and one that knows.

TWO BROTHERS. ONE PASSION. 15+ YEARS.
Kukić Tuning is a family business started by the Kukić brothers in 2010 in Banja Luka. What began as a small workshop is today one of the most trusted addresses for auto electronics and chip tuning in the region.
Our philosophy is simple — we do the job the way we would do it on our own car. We use only original professional equipment, continuously develop our skills, and follow the latest technologies.
Over 1000 satisfied clients and more than 5000 solved ECU units speak of the experience and dedication behind every job we do.
WHAT CLIENTS SAY
“Excellent service, professional approach. They did a Stage 2 on my Golf 7 GTD and the difference is fantastic. I recommend to everyone.”
“The ECU in my BMW refused to work, other shops wanted to replace it for a huge amount. Kukić repaired the original and everything works perfectly.”
“Airbag module after a crash — repaired and returned on the same day. Fair price, quality work, good communication.”
FREQUENTLY ASKED QUESTIONS
The price depends on the brand, model, engine and type of remap (Stage 1, 2 or 3). Send us an inquiry with your vehicle details or call directly — we return a precise, no-obligation quote the same day.
No, if it's done professionally. A Stage 1 map stays within the safe limits the manufacturer allowed. For Stage 2 and 3 we recommend hardware upgrades (better intercooler, exhaust) so the engine runs safely at higher power. We always run diagnostics before any work.
Stage 1 is usually completed the same day (3-5 hours). Stage 2 and 3, or jobs that include ECU repair, may take 1-2 days. We schedule the appointment in advance.
Chip tuning can technically affect the warranty if the vehicle is still under manufacturer warranty. We use reversible maps — we can restore the original factory software at any time before a service or inspection.
In normal driving, consumption is often the same or lower thanks to better engine response. If you use the extra power, consumption will naturally rise proportionally.
We repair ECUs at component level — drivers, microcontrollers, memory chips. In 90% of cases we can repair the original without an expensive replacement. BOSCH, SIEMENS, Magneti Marelli and others.
Always book an appointment first. Call or send an inquiry — we agree on the day and time to bring the vehicle so you don't wait unnecessarily.
Yes, we provide a warranty on all our work. The exact terms depend on the type of service — chip tuning, ECU repair, or airbag — and are agreed before we start.
