I can scan mine also.
When I hooked up the Diablosport InTune, at first it told me my vehicle wasn't compatable, but it said to plug in to a computer and it would download a new PCM configuration file. I did that and it downloaded a new file, installed it on the PCM, and then everything worked just fine.
There's something not meshing up with HP Tuners and a few of these PCM's it seems.
