BMW MS42 Tuning, EWS Delete & DME Service

Siemens MS42 DME service for supported BMW M52TU applications, including the E46 323i/328i, E39 528i, and Z3 2.5.

Available services include a 93-octane performance calibration, European/EU2 configuration, DME virginization for replacement use, and full EWS delete for supported applications. The performance calibration typically adds approximately 15 wheel horsepower on a compatible vehicle. Actual results vary with engine condition, hardware, fuel, and testing method.

A virginized replacement DME must still be aligned to the vehicle with appropriate BMW diagnostic software. EWS delete is a different service and does not use the normal alignment process.

Choose whether you are sending your original DME or need a replacement unit, then select the required programming. Include the VIN, chassis, engine, transmission, hardware changes, fuel, and intended use with the order.

Modified emissions configurations may not be legal for road use in every location. Readiness-monitor results are not guaranteed.
