Went on the Dyno today to tune a Customer Vehicle and my MPVI2 unit can no longer be recognized. I installed the latest software and driver but no luck. When I look in the Device Manager it recognizes it as a "USB Serial Converter" I've tried different cables and different ports. Windows does make the audible connection noise and the unit powers up as well.
Both the scanner and the editor can't recognize it and it won't sync. I have tuned many vehicles with this unit before but no luck today. Luckily I still have the MPVI1 so I was able to get the car out.
Anybody else have this issue??
