I have recently had some customers in europe having problems setting up drives. I then asked them to email me their vipertune settings in a screen shot... and all the settings were all ZERO !

It seems the extreme cold of the cargo bay on some airplanes can go below the cpu's temperature range and erase the EEprom in the DCPic30F3010 or . DCPic30F3011 which i use on the Viperdrives.

The simple cure is to use the ' z ' command in the terminal window to reload the defaults , "Then burn to drive"
