Please NOTE that BMW dealers now have the technology to flag your vehicle as having the DME modified even if the flash has been removed and replaced with the stock tune and this may impact your cars warranty. You accept full responsibility for the purchase and use of this aftermarket tune for your vehicle.

 Active Autowerke offers unparalleled performance software. Through careful remapping of the factory BMW DME tables, various elements such as ignition timing, fuel delivery, and part throttles are reworked to create performance gains. The Active Autowerke upgraded software is designed to operate with gasoline that has an average octane rating with full emissions to create a clean burning combustion with good AFR's all within factory specifications.

Active Autowerke's B58 Performance Software bundle includes stage 1, stage 2 and stage 2 with super high flow cat tunes! We have an option to include the Femto end user program and cable to enable you to do the software flash. WARNING - when flashing your ECU, it is important that you connect a battery charger to your car in order to provide a stable voltage source regardless of your battery condition and you must remove any sleep options on your laptop. If your car has updated software after November 2019, you must not purchase the Femto option and must send the ECU to us for flashing.
