Anybody know what causes a failed flash? Had it happen tonight on my 03 silverado. This has happened twice on this truck. Had it also happen on a 2010 camaro ss but so far have been able to do a full flash and get it up and running again. Pretty scary when this happens when I'm setting in a parking lot with nobody around to pull me home. Never had this issue when I had the old V1 but this V2 has done it a few times. Anybody have any ideas? Need to do some tuning on my 07 corvette but I'm kinda scared to do it for fear of this happening. i always make sure all lights are off and heater fan and all. Running version v8 2.2.289
