Chip tuning for Kia Stonic (KX1) 1.2i MPI 84 hp ECU

Kia Stonic (KX1) (2017) 1.2i MPI 84 hp — mass-market petrol engine of the passenger segment of the Hyundai Motor Group group (Корея, 1967). A petrol engine built in 2017 — a Tricore platform without strong protection; OBD access works.

Kia shares platforms and engines with Hyundai and Genesis. Kia is a Korean carmaker, part of the Hyundai Motor Group. Kia is positioned alongside Hyundai, with an emphasis on styling and a sporty character. Smartstream is Hyundai's modern engine range with an emphasis on economy. Hyundai's factory calibration is mainstream and leaves headroom for Stage 1. T-GDI is Hyundai's badge for its direct-injection turbo petrol engines.

Within Hyundai Motor Group, ECUs are partly shared, so Hyundai files often work on Kia. On older-generation Hyundais, Stage 1 goes in over OBD without Bench. The Hyundai community in Eastern Europe has a large pool of ready-made Stage files. On naturally aspirated Hyundai engines, the main effect is on throttle response. Low-output Hyundai engines are city units, and Stage 1 is safe.
