I have tried about ten different ways to get this feature to function with my PCIII USB and it does not work. I followed the install instructions to the letter from the website and I get an error message when I try to connect my USB after the download that says "error connecting to powercommander, another device is already connected". So I go through the whole process after first connecting to the PCIII and I get an error from the accellerator pump utility saying "no powercommandder connected". Of course their technical assistance line is closed, any ideas anybody?
