This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2017 BMW 550i GT 4.4L AT gas models.
Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with our cloning service.
Built to OEM standards for reliability, calibration accuracy, and long-term performance.
Strict Testing & Quality Assurance
Every ECU is inspected, refreshed, and verified through advanced diagnostic tools. Testing includes:
Complete communication & CAN-bus verification
Sensor input/output and signal integrity checks
Injector & ignition pulse simulation
Power, ground, and load-circuit analysis
Flash memory integrity and checksum validation
Thermal and voltage-stress testing to confirm reliability
Important Note
Some vehicles with IMMO or PATS require key programming after installation. This is normal.
For a 100% plug-and-play solution, we recommend using our full cloning service. We transfer all security data to the replacement unit.
A prepaid shipping label will be emailed to you. Allow you to mail in your original computer to us for full cloning.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

I recently purchased the ECM for my 2017 BMW 550i GT, and I’m very impressed with the entire experience. The unit came VIN programmed, so installation was straightforward, and the plug-and-play setup saved me a lot of time. Shipping was surprisingly quick and reasonable, arriving well within the estimated window. Throughout the process, the seller was very responsive, answering my questions promptly and keeping me informed about every step. So far, the car runs perfectly, and I couldn’t be happier with the quality and service.
