BMW M57 ECU Remap

BMW M57 ECU Remap for Custom Conversion Projects

This product includes a custom BMW M57 ECU remap service for engine swap, retrofit and custom vehicle conversion projects. It is intended for M57-powered builds where the factory ECU software needs to be adapted for a different vehicle platform, drivetrain setup or standalone engine installation.

Please note: this product does not include the ECU itself. You can purchase a compatible RAW ECU separately from our stock, or send us your own ECU for programming.

Information Required Before Programming

• Current ECU version or ECU part number
• Engine code and engine variant
• Injector codes and injector type
• Turbocharger setup
• Transmission type
• Vehicle platform and project description

Available ECU Software Modifications

• IMMO off using software modification only
• Custom remap according to your project requirements
• DPF off, if the vehicle is equipped with DPF
• EGR off
• MAF off on supported ECU versions
• Vehicle speed signal dependency removal for standalone engine operation without ABS signal
• Removal of unnecessary conversion-related fault codes
• Electronic turbo to vacuum turbo conversion support
• Vacuum turbo to electronic turbo conversion support

Important: MAF off is not possible on all ECU versions. In many projects the MAF sensor must remain installed because it provides the intake air temperature signal required by the ECU.

Typical Applications

• BMW M57 engine swap projects
• Nissan Patrol M57 conversions
• Standalone M57 engine installations
• Off-road and overland vehicle builds
• Custom diesel performance projects
• Manual and automatic transmission conversions

Each ECU remap is prepared according to the engine specification, injector setup, turbocharger configuration, transmission type and intended vehicle use. If you are unsure which software modifications are required, please contact us before placing your order.
