ECU Tune Software

By directly recalibrating the DME (Digital Motor Electronics), this software achieves a notable increase in both horsepower and torque. Specific modifications are made to the air/fuel ratios, ignition timing tables, and wide-open throttle maps to deliver a more engaging and responsive driving feel. This performance software is optimized for use with 91-93 octane fuel, allowing you to maximize your car's performance gains while maintaining reasonable fuel consumption. Additionally, it includes an increased RPM limiter specifically for manual transmission vehicles, providing access to more usable power throughout the rev range. For enthusiasts looking to extract more performance from their existing modifications, this software is a crucial upgrade. The Active Autowerke Performance Software is compatible with a range of BMW E46 and E39 models from 1999 to 2003, including the 323Ci, 323i, 325Ci, 325i, 325xi, 330Ci, 330i, 330xi, 525i, 528i, and 530i. It is recommended for those seeking to maximize their vehicle's performance potential beyond stock specifications.
