Stage 1 chip tuning raises power from 136 to 180 hp (+44 hp, +32%) and torque from 220 to 260 Nm (+40 Nm). ECU — Bosch MD1CS001. Flashing method: OBD or Bench depending on the unit's protection. A modern petrol engine built in 2019 — a generation with encrypted ECU protection (Tricore TPROT); top engines require Bench.

BMW is a premium manufacturer from Munich, founded in 1916 as an aircraft-engine works. The BMW petrol range spans the mainstream segment and the sporting M-series. Mid-range BMW turbo petrol engines are a mainstream Stage 1 subject with a proven base. The factory calibration on BMW petrol engines is conservative, leaving headroom for Stage 1 without hardware changes.

The BMW community is renowned for active tuning and a large pool of available Stage files. Stage 1 on standard mid-range BMW petrol engines delivers a noticeable gain with no hardware changes. Protection on top BMW models is the toughest in the group and requires Bench. Mid-range engines form the backbone of the range, and Stage 1 preserves engine life. The mainstream base is the most refined chip tuning segment in Europe. The factory calibration is conservative, with headroom for Stage 1 and no hardware changes.
