Expertly calibrated and meticulously refined, DME Tuning’s ECU software is guaranteed to give you MORE of a good thing. More horsepower, more torque, and a more exhilarating driving experience by delivering usable power through improved throttle response and torque management. With additional ft. lbs. of torque through the mid-range, acceleration out of your favorite corner and onto the straight is noticeably quicker throughout the rev range. DME Tuning saves your stock/factory ECU settings so that you can revert your vehicle back to stock settings at any time.

ECU UNLOCK

DME can tune 2021+ BMW's (06/2020+ build date). The turn around time is 2 weeks since the DME has to be sent to Europe for unlocking. Pricing includes ECU unlock, tune and shipping.

 

NOTE

You will need to disable the AUTO UPDATES by going to the following in the iDrive menu. Car > Settings > General Settings > Data Privacy > Select "No Service". If the iDrive asks you to update your apps, do not do this. It will lock the ECU again and you will lose your tune/unlock.
