I have a 2011 1500 Silverado. I was able to complete the Data-Log step. I was also able to complete the Tune File Retrieval for the engine controller. When I attempted the next step, the Tune File Retrieval for the transmission controller, the AutoCal screen displayed, "File Sys FULL!" This was followed by "ERROR: $0520" I attempted the steps again with the same results. Anyone experience the same? If so, what was the solution? THX!
