Chip tuning for Seat Mii 1.0i CNG 68 hp ECU
Seat Mii (2012) 1.0i CNG 68 hp — mass-market petrol engine of the passenger segment of the Volkswagen Group (VAG) group (Испания, 1950). Stage 1 chip tuning raises power from 68 to 78 hp (+10 hp, +15%) and torque from 90 to 100 Nm (+10 Nm). A petrol engine built in 2012 — a Tricore platform without strong protection; OBD access works.
Seat is a high-volume VAG brand with a sporty character and Mediterranean design. The factory calibration of Seat petrol engines is conservative, leaving headroom for Stage 1. Low-output Seat petrol engines are naturally aspirated; the gain is modest but safe. Mid-generation petrol models use standard OBD flash.
Within the VAG group, ECUs are standardised, so Seat files often work on VW/Audi/Skoda. The Seat community benefits from a large pool of Stage files drawn from the shared VAG catalogue. On pre-2017 Seat models, Stage 1 is done via OBD without bench. In the Seat city segment, Stage 1 is more about comfort. On low-output Seat engines, Stage 1 is safe. On naturally aspirated Seat engines, the main effect is on throttle response.
