BMW MSS70 / MSV70 EWS Delete (2006-2008 E85/E86)

| /


We are one of the few that offer EWS deletes for MSS70 and MSV70. 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 $300 per ECU. You will need to ship your ECU(s) to us for the EWS delete. We cover return shipping.

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!
