I know that TTS Data Master and possibly EFI Live are good options for the OBD1 LT1 , but what are people using for OBD2 LT1's ? Curious to know if anyone has had success using EFI Live to log enhanced GM PIDs .

Some other tools that are advertised to work, but how well I'm not sure:

AutoTap

Palmer Engineering ScanXL

Ease Diagnostics

Auto Enginuity

If anyone can add to the list or comment on any of the above tools, it would be much appreciated .
