I just bought a edge evolution, it was used but worked on the truck it came off of. I followed the instructions and it cleared my ECM to upload it with the fuel economy setting, I then got a error message saying there was already a program uploaded. I bought a 08 duramax last week, so i plugged the evolution into my computer, got the new downloads and now I have an error code 81, Plus my truck is dead where it sits, has power but ECM is cleared. Edge is closed and i'm stuck. Anyone help? I tried rebooting but continue to get the error message.:help
