    Default 2011 LML ecm

    How is the best/easiest/cheapest way to change the vin in a used ecm to my truck vin? I am replacing my ecm with a used one. I understand I will have to put in injector flow data.

    If you have Efilive, plug in your Flashscan or Autocal inline with your laptop, and connect it to your truck. Open Efilive Scan and Tune, and select the F4:OBD tab. A window will open and one of the tabs in that window will be VIN change.
