Genesis G80 (2016) 3.8 GDI 315 hp — premium petrol engine of the passenger segment of the Hyundai Motor Group group (Корея, 1967). Stage 1 chip tuning raises power from 315 to 330 hp (+15 hp, +5%) and torque from 397 to 420 Nm (+23 Nm). ECU — Siemens/Continental SIM2K-260. Flashing method: OBD or Bench depending on the unit's protection. A petrol engine built in 2016 — a Tricore platform without strong protection; OBD access works.

Genesis is positioned as a Korean rival to Mercedes, BMW and Audi. Genesis is the premium sub-brand of the Hyundai Motor Group, launched in 2015 as a standalone brand. Genesis shares platforms and engines with the Hyundai N series. 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.

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. Within Hyundai Motor Group, ECUs are partly shared, so Hyundai files often work on Kia. High-output Hyundais are the N-series and Santa Fe, with solid headroom for Stage 1.
