Audi A1 (2018 - GB) 25 TFSI (1.0) 95 hp — premium petrol engine of the passenger segment of the Volkswagen Group (VAG) group (Германия, 1909). Stage 1 chip tuning raises power from 95 to 135 hp (+40 hp, +42%) and torque from 175 to 230 Nm (+55 Nm). This engine ships with different ECU variants: Bosch MED17.1.27, Bosch MG1CS011. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 2 configurations · 2 ECU variants. A modern petrol engine built in 2018 — a generation with encrypted ECU protection (Tricore TPROT); top engines require Bench.
Audi is part of the Volkswagen Group (VAG), Europe's largest automotive group. Audi Sport is Audi's performance division, building the RS models. Audi shares platforms with Volkswagen, Porsche, Bentley and Lamborghini within VAG. Audi shares its ECUs and calibration algorithms with Volkswagen. Low-output Audi petrol engines are naturally aspirated; the gain is modest but safe. TFSI is Audi's signature designation for direct-injection petrol turbo engines.
APR and Revo are the leading tuning brands for Audi, right up to Stage 1+. Within the VAG group, ECUs are standardised, so a single file often fits a dozen models across Audi/VW/Skoda/Seat. The Audi community is renowned for its active tuning scene and a huge library of available Stage files. In the Audi city segment, Stage 1 is more about comfort than outright power. On naturally aspirated Audi engines without a turbo, the main effect is on throttle response. On low-output Audi engines, Stage 1 is safe without overstressing the hardware. Base TFSI/TDI versions focus on fuel economy; Stage 1 delivers an honest but modest gain.
