BMW E39 E46 E53 X5 530i 330i 325i M54 M52TU MS43 Tuning
EWS Delete / Immo Off is NOW AVAILABLE for BMW MS43 M54! KasselPerformance is the only tuner that offers a full EWS delete bypass via software. NO emulator is used! See full video example here.
The Siemens MS43 was originally installed in the BMW E46 325i, 330i, E39 525i, 530i, and E53 X5 3.0.
There is no software EWS currently available for this ECU; however, we do offer “virginized” MS43's. A used MS43 cannot be installed into a vehicle unless it is restored to factory like settings. We offer this service and to provide affordable replacement DME's for E39, E46 and E53 chassis. The virginized DME will need to be aligned with EWS and can be done any of the BMW utilities.
To remove the Secondary Air Pump, rear O2 sensors, and other emissions related systems, the Euro2 tune is recommended.
A virginized DME is setup in the same manner as a factory fresh DME. It will need to be sync’d to the vehicle; however a used DME can be utilized instead of a brand new unit from BMW.
