2011 Lexus IS350 3.5L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2011 Lexus IS350 3.5L 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 89661-53761 ECM for my 2011 Lexus IS350 and couldn’t be happier with the entire experience. The ECU arrived quickly and was already VIN programmed, which made installation straightforward and hassle-free. What really impressed me was how responsive the customer service team was—they answered all my questions promptly and made sure I was comfortable with the process. The shipping was also very reasonable, so I didn’t have to worry about extra costs. My car is running smoothly now, and I definitely recommend this product to anyone needing a reliable replacement.
