Hi, It is possible to push approved tuning (box) files from PC to ECU and also to save from ECU to PC. You cannot change anything but you can view full data readouts with live gauges, look at diagnostic codes and clear historical codes.
So yes the ECU is locked in that you cannot change anything.
But can upload "Official secure" tuning files.
The upload for the Pinking cure or latest file with Fan control would normally be done by dealer, except in the colonies they are on another island. Out of need I have had to do this stuff myself, and it is pretty simple.
S&S Protune software is very similar to if not better than the Morgan software
Hardest part is trying not to lose the extremely small cap screws on the connecter cover !!
