2010 Lexus RX350 3.5L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2010 Lexus RX350 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 was really impressed with how smooth the entire process was from start to finish. The ECM arrived quickly with free shipping, which was a nice surprise. What stood out to me was the professional VIN programming service they provided – it saved me a lot of time and hassle since the unit was ready to go right out of the box. When I had a couple questions about installation, their customer service responded quickly and clearly, which gave me peace of mind. After swapping it in, my Lexus RX350 runs flawlessly, just like new. Highly recommend this product and their service to anyone needing a reliable ECU replacement.
