At Celtic Tuning, we offer a complete range of Hyundai ECU remapping and chip tuning services for petrol and diesel engines. Each remap is created in-house and fully tested on a dynamometer. This allows us to provide software that improves performance, drivability, and reliability.

Our Hyundai ECU remaps give drivers sharper throttle response, more power, and smoother power delivery. Diesel models often see better fuel economy, making our tuning an excellent choice for those seeking both performance and efficiency.

We support Hyundai’s entire lineup, from compact models like the i10, i20, i30, and Getz to family cars such as the Elantra, Sonata, Matrix, and Trajet. Our coverage includes SUVs like the Kona, Tucson, ix35, ix55, and Santa Fe, as well as the rugged Terracan. Larger MPVs and vans, including the i40, ix20, i800, and iLoad, are also fully supported. Performance-focused drivers can also benefit from remaps for the Veloster.

All our software is fully developed and tested on our advanced 4WD Dynocom rolling roads. We have two 4WD Dynocom dynos at our head office in Newquay, Cornwall, and another at our Derby branch. This setup ensures precision, consistency, and top-quality results.

For added peace of mind, we offer a mechanical breakdown warranty along with a 14-day money-back guarantee.
