Chip tuning for Alpina B4 3.0T 495 hp ECU
Alpina B4 (2023) 3.0T 495 hp — sports petrol engine of the passenger segment of the Alpina Burkard Bovensiepen (BMW Group с 2022) group (Германия, 1916). Stage 1 chip tuning raises power from 495 to 650 hp (+155 hp, +31%) and torque from 730 to 850 Nm (+120 Nm). ECU — Bosch MG1CS049. Flashing method: OBD or Bench depending on the unit's protection. The ZF 8HPxx TCU is calibrated with a separate file — torque limiter and shift maps for Stage 1. In the CHIPOK database: 2 configurations · 2 ECU variants. A modern petrol engine built in 2023 — a generation with encrypted ECU protection (Tricore TPROT); top engines require Bench.
Alpina is a German BMW tuning brand, founded in 1965. Alpina is known for a balanced calibration that sits between stock BMW and M GmbH. Alpina specialises in premium tuned versions of BMW (B5, B7, XB7, B8). M GmbH is BMW's performance division, building high-output top engines since 1972.
The BMW community is renowned for active tuning and a large pool of available Stage files. Top BMW engines confidently reach Stage 2 with a downpipe + intake + intercooler. Protection on top BMW models is the toughest in the group and requires Bench. A well-known base once hardware is added (downpipe + intake + intercooler). Bench reading is the standard procedure for top engines in modern models. Top BMW engines sit at the power ceiling, and the gain is significant.
BMW's main gearbox is a modern multi-speed automatic. The TCU rarely needs recalibration up to Stage 1+, as the torque limiter usually copes with the Nm gain. Top BMW models use a reinforced gearbox version that handles significant stock torque.
