M57 204hp Standalone ECU

The M57 204hp Standalone ECU by Spoolas is tailored for enthusiasts performing engine swaps or conversions, offering compatibility with both Euro 3 and Euro 4 engines. It features a fully unlocked unit with the immobilizer disabled for seamless integration into non-BMW projects. Customers can select between health-checked used ECUs or send their own ECU's for modifications. Additional services include performance tuning options, including Stage 1 upgrades and essential deletes like EGR, DPF, and swirl flaps. This ECU provides a versatile solution for optimizing engine performance and reliability in custom street, marine, motorsport and off road builds.

We only recommend using these ecu's in non BMW applications (engine swaps and conversions).
