Chip tuning for Audi A3 35 TFSI (1.5) 150 hp ECU

Audi A3 (2019 - 8Y) 35 TFSI (1.5) 150 hp — premium petrol engine of the passenger segment of the Volkswagen Group (VAG) group (Германия, 1909). Stage 1 chip tuning raises power from 150 to 175 hp (+25 hp, +17%) and torque from 250 to 300 Nm (+50 Nm). ECU — Bosch MG1CS011. Flashing method: OBD or Bench depending on the unit's protection. The Bosch DQ38x TCU is calibrated with a separate file — torque limiter and shift maps for Stage 1. In the CHIPOK database: 4 configurations · 2 ECU variants. A 2019 petrol engine — the latest era of encrypted firmware; OBD access is available on production units, Bench on sport models.

Audi's signature slogan is “Vorsprung durch Technik” (Progress through Technology). Audi is a premium manufacturer from Ingolstadt (Bavaria), founded in 1909 as Audiwerke August Horch & Cie. Audi's petrol range is badged TFSI, and the diesel range TDI. The MQB and MLB platforms allow ECU commonality with Volkswagen, Porsche and Bentley. The Audi community is one of the most open in Europe, with a large library of ready-made Stage files. The factory calibration of Audi petrol engines is conservative, leaving headroom for Stage 1.

On Audi, Stage 1 usually fits within the standard turnaround time. The Audi community is renowned for its active tuning scene and a huge library of available Stage files. APR and Revo are the leading tuning brands for Audi, right up to Stage 1+. In the mid segment, the Audi community is an open platform with a large library of ready-made Stage files. The factory calibration is conservative, with headroom for Stage 1 and no hardware changes. The MQB platform is the most refined chip tuning segment in Europe. Mid-range Audi engines form the backbone of the range; Stage 1 preserves engine life.

S tronic comes in dry and wet-clutch versions, each with a different torque rating. The S tronic TCU requires calibration at Stage 1+, as the torque limiter usually sits below the engine's potential. Tiptronic is Audi's classic automatic for longitudinally mounted engines.
