Frequently Asked Questions
Is this ECU pre-programmed, or do I need to flash it?
This is a used OEM module. It is pre-programmed from the donor vehicle and is ready for installation. In most cases, it will require a brief vehicle adaptation procedure using a professional scan tool to sync with your car’s security system (SKIM).
How do I ensure this part will work with my specific 2020 Chrysler 300?
Compatibility is critical. You must compare the part number on your original ECU with the number shown in our product images. We also strongly recommend providing your vehicle’s VIN at checkout so our team can perform a final verification before shipment.
What is your testing process for this ECU?
Every ECU we sell is visually inspected for damage, then bench-tested for power-up and communication. We verify it is not locked or “virginized.” Our staff notes confirm this unit operates correctly with standard parameters.
