Can you remap Hyundai T-GDI engines?

Yes, we specialise in T-GDI tuning. These turbocharged engines respond exceptionally well to remapping, with gains of 25-40bhp on Stage 1.

Do you tune Hyundai CRDi diesels?

Absolutely. Our CRDi remapping unlocks significant power and torque gains while improving fuel efficiency and drivability.

Is Hyundai remapping safe?

Our Stage 1 remaps are developed within safe parameters for your engine. We use proven calibrations tested across thousands of vehicles.

Our Services for Hyundai

Hyundai's 1.6 T-GDI engine — found in the Tucson, i30, and Kona — gains 25-40bhp through optimised boost pressure and ignition timing. The 1.6 and 2.0 CRDi diesels in the Tucson and Santa Fe see 30-50bhp with dramatically improved low-end torque for towing and loaded driving. Hyundai's Bosch MED17 and EDC17 ECU platforms share architecture with European manufacturers, making calibration development well-proven and reliable.

Hyundai's N division has created genuine hot hatch contenders. The i30 N's 2.0 T-GDI (275bhp Performance) gains 30-50bhp through optimised boost pressure and ignition timing — rivalling far more expensive machinery. The i20 N's 1.6 T-GDI is similarly responsive to tuning. We also optimise the N DCT gearbox for faster shifts and improved N Grin Shift behaviour. The Kona N receives bespoke calibrations for its crossover-specific power delivery requirements.

Hyundai's CRDi diesel engines — particularly the 1.6 CRDi in the Tucson and i30 — respond well to economy calibrations with 10-15% fuel savings through optimised injection timing and rail pressure curves. The Santa Fe's 2.2 CRDi is popular for economy tuning among owners who need the vehicle's towing capability but want to reduce the cost of their daily commute. We calibrate for cruise-speed efficiency without reducing available torque.

Hyundai CRDi diesels — particularly the 1.6 in the Tucson and i30 — can develop DPF issues from urban driving patterns. The EGR system on these engines uses a cooled EGR valve that's prone to carbon buildup at higher mileages, causing rough idle and reduced performance. We diagnose through Hyundai GDS-compatible protocols, identifying whether the issue is soot loading, differential pressure sensor failure, or EGR fouling, and apply the correct software solution.
