I've been having a lot of 'lost' connection & cable-not-found errors with the scanner program.
Putting dielectric silicone grease in my cars OBDII 'port' seems to have 'solved' those problems.
It's the same stuff that you use for spark plug wires, & can be found at any auto parts store.
Norton antivirus is a pain in the a@@.
You can't just 'disable' it when your using HPTuner.
It enables itself sometimes during the middle of a scan...
Why does it do this by itself....
You got to turn it off via 'options', then restart your laptop so that it doesn't 'load' at startup.
