This engine ships with different ECU variants: Siemens/Continental SIM2K-240, Siemens/Continental SIM2K-240R, Siemens/Continental SIM2K-250. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 3 configurations · 3 ECU variants. The 2015 generation — mid-generation petrol ECUs (MEDC17/MEVD17/Simos PCR), OBD flash on production revisions.
The Stinger is Kia's performance saloon with a turbo V6. The EV6 is Kia's flagship electric crossover, built on the E-GMP platform. GT is Kia's sporty trim package. High-output Hyundai N turbo petrol engines deliver a solid gain with Stage 1. Smartstream is Hyundai's modern engine range with an emphasis on economy. Hyundai's factory calibration is mainstream and leaves headroom for Stage 1.
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. High-output Hyundais are the N-series and Santa Fe, with solid headroom for Stage 1.
