BMW 3-serie (2005 - E90) 16i (N45B16) 115 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 115 to 120 hp (+5 hp, +4%) and torque from 150 to 160 Nm (+10 Nm). ECU — Bosch MEVD17.2. Flashing method: OBD or Bench depending on the unit's protection. The 2005 generation — old-era petrol ECUs (ME7/ME9/MED9/Simos) with easily readable memory.
M GmbH is BMW's performance division, building M engines since 1972. The factory calibration on BMW petrol engines is conservative, leaving headroom for Stage 1 without hardware changes. On older-generation BMW petrol engines, Stage 1 goes in over OBD without Bench. Third-party flash platforms are an industry of their own for the BMW community.
Stage 1 on BMW usually stays within the standard timeframe, with no particular difficulty on the standard models. Stage 1 on standard mid-range BMW petrol engines delivers a noticeable gain with no hardware changes. The BMW community is renowned for active tuning and a large pool of available Stage files. 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. The mainstream base is the most refined chip tuning segment in Europe.
