What does reprogramming your car do?
Car computer reprogramming, which is also known as flashing, is a process which erases the old engine control modules or ECMs at which time the most recent software from the manufacturer is installed. To do this, we use a special device called a scanner which we connect to the diagnostic port of your vehicle.
Does an ECM need to be programmed?
Will A New ECM Need To Be Programmed? Your engine takes a beating over time. While it’s built to last, it needs to be reprogrammed to ensure that everything is functioning optimally. Even if you’re installing a new ECM in your old vehicle, it doesn’t have to be reprogrammed to match its specifications.

How do you know if your car has ECM?
The least invasive way to diagnose your ECM is to connect an onboard diagnostic (OBD or OBD II) tool to the diagnostic port. From there, you can scan to see if your engine computers have produced any error codes. There are many of these codes, and your diagnostic tool’s manual should have information on what they mean.
