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.

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 shipping and the unit was ready to go right out of the box. This saved me a ton over dealer repair costs, and their communication throughout was spot on.
Shipping was speedy and the programmed ECM was literally plug-and-play. Installing it was hassle-free, and I’m really glad I avoided the expensive dealer route.
The ECU came fast and worked perfectly with no extra programming needed. Their professional service saved me a lot of money versus the dealership, and installation was smooth.
