The VIN might not have the proper programming depending upon the transmission type of the car and hence cause unwanted car troubles.

  3. Additionally, the coding could be different and pose problems in case you have to emission requirements in your state.

  4. Another thing to consider is that the used ECU set comes with a key that will no longer fit in the ignition switch of the car, hence you need to spend extra money and time to change the ignition car. Furthermore, the door locks of the car would need replacement as well.
