BMW M57 ECU Rebuild for Conversion Projects

BMW M57 ECU Rebuild for Custom Conversion Projects

The BMW M57 ECU Rebuild is a fully reprogrammed engine control unit designed to make your M57 swap run flawlessly in custom builds outside the original BMW platform. Ideal for off-road vehicles, race cars, or bespoke automotive projects.

Key Modifications

• Immobilizer Removal (IMMO OFF): Software-level deactivation, no extra hardware required
• Emissions Deletes: EGR, DPF, and DSC functions removed for simplified operation
• Optimized Diagnostics: Removal of non-essential DTCs so only relevant system faults are shown
• MAF Delete (Air Mass Meter Disabled): ECU no longer requires MAF input for operation, but sensor have to be retained for air temperature readings
• ABS/Speed Signal Not Required: Engine delivers full power without vehicle speed input – no limp mode

Performance Enhancements

• Custom power remap for increased performance
• Multiple tuning levels available
• Support for custom turbo configurations (vacuum to electric conversion, bi-turbo nozzle control)
• Compatible with upgraded fueling and boost sensors (up to 2700 bar rail pressure and 4 bar MAP sensor)

Applications

Perfect for M57 swaps into off-road rigs, drift cars, expedition builds, and performance vehicles where OEM restrictions need to be removed.

Customization Options

We can tailor the ECU software to your specific build requirements, from keeping original settings for road-legal conversions to full custom remaps for high-performance projects.
