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 may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.
