BMW MS45.0 / MS45.1 EWS Delete (E46, E60, E83, E85)

| /


We are one of the few that offer EWS deletes for MS45. Commonplace on race cars, an EWS delete allows for "hot swapping" ECUs. Customers can have multiple ECUs with different configurations and switch between the ECUs at any time. Please note that EACH ECU requires an EWS delete modification at $200 per ECU. You do not need to mail in your ECU(s) for the EWS delete. The EWS Delete is a remote service performed to a customer-provided ECU. If a K+DCAN cable is required, please enter shipping information at checkout.

Disclaimer - Flash tuning is separate from coding and diagnostics. It will not solve underlying mechanical or electronic issues, and in some cases, it can make problems worse. We highly recommend you consider tuning to be a final ECU calibration and the very last step when optimizing your vehicle. Recommended for off-road use only!
