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.

Connor Cook –
Swapped this ECM into my ’07 Monte Carlo and it fired right up without a hitch—super quick delivery and smooth installation.
Exactly what I needed for my Chevy, arrived fast and worked perfectly out of the box, no fuss at all.
This ECU was a flawless fit for my Monte Carlo, and the VIN programming saved me hours of hassle—highly recommend!
Great product, easy install with zero issues, and their customer support was really helpful when I had a question.
Plugged it in and it was like my car got a new brain—runs great and was dead simple to install.
