2005 Jeep Wrangler 4.0L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2005 Jeep Wrangler 4.0L 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 quickly the ECM arrived after I placed my order, it showed up much sooner than I expected. Installing the unit on my 2005 Jeep Wrangler was straightforward since it came fully programmed and ready to go—definitely a plug-and-play experience. This saved me a ton of money compared to getting it done through the dealership, which was quoting me an outrageous price. The seller was very communicative and answered all my questions promptly, which made the whole process less stressful. Overall, the installation went smoothly, and my Jeep is running perfectly now. I’m very happy with the purchase and would recommend this to anyone needing a reliable replacement ECU.
