Stage 1 File Modification – BMW E87 118d 143HP

This service includes the preparation of an individual Stage 1 file for the engine control unit in a BMW 1 Series E87 118d with a factory power of 143 HP. The modification involves optimizing the operating parameters of the engine by changing the maps in the ECU.

The calibration is performed based on the original ECU readout from the vehicle. This ensures the file is tailored to the specific software version, ECU number, and engine configuration.

During the modification, the following are optimized, among others:

• fuel injection map

• turbocharger boost pressure

• torque limiter

• torque map depending on gear

• injection strategy

The goal of the modification is to improve engine flexibility and increase torque in the mid-range RPMs, which significantly enhances driving dynamics.

Performance after modification

Exact values depend on the vehicle's technical condition and the engine control unit version.
