ECU tuning can be installed through the following methods
1) Purchase a flashzilla V3 from our website https://tunezilla.com/flashzilla
2) Contact and book an appointment through a distributor https://tunezilla.com/dealers
3) Bench flashing: The ECU must be shipped in or tuned by a distributor with bench tools. This is not recommended as they can easily be tuned through the diagnostic port.
Late 2015 model vehicles may require bench-flashing if they have the newer ECU revision. 2016 and newer BMW diesels must be bench-flashed. If you're unsure if your vehicle requires bench-flashing you can provide us with your DDE (engine control unit) information by taking a photo of the part #, or attempting port flashing.
Install instructions:
Flashzilla V3
Download and install the flashzilla V3 software https://tunezilla.com/fz/guide
Plug the device into your obd port, go through the tuning menu and select your ECU: EDC17C50 for 2014-2015 328D and EDC17C56 for 2014-2015 X5 + 535D. In the rest of the global market BMW goes by displacement for vehicle branding, don't worry if your 328d or 535d come up as a 320d or 530d, only the ECU version is important.
