Read it and look at the calibration info. Then find a stock tune with the same calibration info and use the compare feature of the software to see the differences.

The LS1b 512kb PCMs are interchangeable with the proper operating system flashed into them. If it is a 610 PCM and has had a "Full Flash" flashed into it from a 2002 WS6. Then it should read out as a 12200411 PCM with a 12212156 Operating system. If you wanted a 2002 WS6 tune, then you should be good to go.
