Injector & ignition pulse simulation
Power, ground, and load-circuit analysis

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.

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.

Adam Stewart –
The ECM arrived quickly and was exactly as described for my 2009 Mercedes-Benz GL-Class. Installation was straightforward since it was already VIN programmed, making it truly plug-and-play without any extra hassle. After swapping it in, my vehicle started right up and runs smoothly, so I’m very satisfied with this purchase. The support team was also helpful when I had a couple of questions before buying.
