This file delivers Stage 1 gains for Hyundai’s 2.2-litre CRDi, widening the torque plateau without upsetting factory refinement. DPF regeneration logic and EGR flow are fully disabled, lowering exhaust back-pressure and keeping the intake charge clean. Torque, boost and smoke limiters are rescaled with safe λ-targets so the automatic transmission remains within clutch capacity even while towing. Cold-start, idle and part-throttle maps are retuned to keep OEM fuel economy on cruise, yet boost arrives about 300 rpm earlier for brisk overtakes and smoother urban drivability.
