Montey from ATP has helped me as far as he can. We both have agreed we think something is wrong with my black box. When i go to the firmware update all boxes show N/A and the computer knows its plugged into the usb port but it cannot recognize anything. The black box shows its in usb mode and ive done the hold CTL button and plugged it in. NOTHING!!! Im trying to upgrade it to the cummins version. It works for duramaxes but nothing else. All software that Montey and I are aware of is up to date. THanks, Eric
