The VCM Scanner is the best tool I have seen offered as included complimenting software to any aftermarket Calibration Software.
It is quite overwhelming to step into a new software and see miles of features that are available for use. Hopefully these videos should get you started and help you better understand the features of the software.
These videos cover the basic operations of the software and leave the complicated customized parameters out to prevent initial confusion. If you wish to learn about Custom PIDS and Auxiliary I/O search the forum for the specific setup you are trying to read or control. Chances are it has already been done before and the setup instructions are already laid out very clear. Auxiliary I/O come in many forms and because of that I have left them out as it would take forever to explain the setup procedures for every option.
I hope these videos help you establish a quick start and/or insight to the product you are about to or have already purchased.
