Anyone here flash their PCM on thier truck? I asked the local dealer where I am at if they would re-flash or re-load my PCM. They said when they hook it up to the PC that they use, it says the PCM has the "Latest verion" and it will not re-flash because it already has the most current version. Basically the PCM is like a heavy duty solid state hard drive, and has a program on it. So just like you have Vista or Windows 7 on you PC it could be loaded incorrectly or have some problem. So you take the CD or DVD and reload it. Can I just re-load my PCM with the most current version? Anyone ever work with this stuff?
