Hey Tom,
I am using both Autoenginuity's product, as well as PCMSCAN, and yes, it has very nice features
The ability to design your own dash (gauges) is nice, better than what most allow you to do. Although I have the expanded software set with the Autoenginuity, the userinterface is propietary, there is a limited amount what you can adjust in it, basically configuration settings, that's it.
The PCMSCAN allows a lot more, even has a command-line interrogation tool.
What hardware are you using with yours?
