Ordered and received new tool, registered new tools. ensure credits were avail. A fear I had! plugged in to vehicle and data logging started no issue. drove over to professional hotrodder, a friend and he showed me how easy it was saving base tune and creating a new tune IE made one change to torque management. very easy until < during write operation begins stops at around 4% and times out message occurs. vehicle will not start now. reloaded base tune and process begins and then again times out. we are always able to read and begin writing the farthest it got was when I tuned radio off went to 16% but the radio rebooted, and dinger occurred and then time out message. My fault I didn?t bring laptop charger, so before It lost power we unplugged shut down and reconnected and was able to begin download and it timed out again. I?m thinking radio is the issue an aftermarket unit with connection to BCM via adapter module. In the am, I will either pull fuse or radio install factory and reattempt. any thoughts
