Description
2012 RAM Ram Truck 5.7L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2012 RAM Ram Truck 5.7L 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.

Super fast turnaround and the VIN programming was spot on—truck fired up with no issues. Shipping was free, which was a nice bonus!

I was really impressed with how smooth the entire process went. The RL150635AB ECM arrived quickly with free shipping, which was a nice bonus. What really stood out was the plug-and-play setup—they had it fully programmed for my 2012 RAM 5.7L before shipping it out, so installation was a breeze. The truck fired up immediately without any issues, and I’ve noticed a definite improvement in performance. Customer support was responsive and helped answer a few questions I had along the way, making the whole experience stress-free. Would definitely buy from them again if I ever need another ECU.

I recently purchased the RL150635AB ECM for my 2012 RAM 5.7L, and I couldn’t be happier with the entire experience. The unit arrived quickly, and the free shipping was a nice bonus. What really stood out was their professional programming service—my truck was up and running without a hitch right out of the box. They also kept me in the loop throughout the process, which made me feel confident in what I was buying. This was hands down the smoothest ECM replacement I’ve ever done.
