I got the same problem!
I just flashed a brand new PCM from GM using GM SPS. I flashed a 2009 Corvette cal into the PCM, then read it with HPT. When I saved the file HPT told me that the file was locked. So I reflashed the...
Well, were not going to do that on this trip!
OK I did that finally got the cal read, but its telling me that it can't read the TCM and it needs your support to unlock the TCM what do I need to do
I am using 3.6.26 I have tuned several 2017 Corvettes without issues other than getting into your server. I am also using the old MPVI 1 box not your new interfaced.
I get this error "Controller Unlocker Web Service Exception " is there something wrong with the HPT server today? I am trying to read a 2017 Corvette and naturally the customer is from out of town...
