Yes, you're correct. In some cases, you might only need to update the immobilizer (IMMO) and the Vehicle Identification Number (VIN) to make the used ECM compatible with your vehicle. The immobilizer system prevents the engine from starting without the correct key, so reprogramming the IMMO is necessary to ensure your key will work with the new ECM. Reprogramming the VIN is also essential for proper communication between different vehicle modules and to avoid any diagnostic trouble codes or issues with emissions testing. Although these updates may be sufficient for some vehicles, it's always a good idea to consult a qualified mechanic or dealership to ensure the used ECM is compatible with your specific vehicle configuration. They can also provide assistance with reprogramming the ECM if required.

If you buy a used computer will it be plug and play or do I have to get it reprogrammed as well
