BMW 4-serie (2013 - F32-F33-F36) 18i (1.5T) 136 hp — premium petrol engine of the passenger segment of the BMW Group (Mini, Rolls-Royce, BMW Motorrad) group (Германия, 1916). Stage 1 chip tuning raises power from 136 to 175 hp (+39 hp, +29%) and torque from 220 to 260 Nm (+40 Nm). ECU — Bosch MEVD17.2.3. Flashing method: OBD or Bench depending on the unit's protection. The 2013 generation — mid-generation petrol ECUs (MEDC17/MEVD17/Simos PCR), OBD flash on production revisions.
BMW has always emphasised driver engagement — a signature trait of the brand. Mid-generation petrol models use standard OBD flash. Third-party flash platforms are an industry of their own for the BMW community. Mid-range BMW turbo petrol engines are a mainstream Stage 1 subject with a proven base.
On older and mid-generation BMWs, Stage 1 is flashed over OBD without Bench. Stage 1 on BMW usually stays within the standard timeframe, with no particular difficulty on the standard models. The BMW community is renowned for active tuning and a large pool of available Stage files. 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. Mid-range engines form the backbone of the range, and Stage 1 preserves engine life.
