I apologize if there is another thread with the same problem as me. But I looked through them all and none seem to fit my issue. Every time I try to program or even reading a tune or calibration. no mater if it ECM, TCM, calibration or full flash. About 19 out of 20 times in the middle of the programing or sometimes before it even starts it will unlock and then say "No Data Received". If I keep trying it will eventually work through V7 V8 or through the actual device, but it all varies. Its just a little scary when it erases and then boots you out and you can't get in. And yes everything is up to date from the drivers to the software and firmware. Is anyone else having this problem?
