One way that springs to mind ( with a few conditions of course ) Put a sniffer on the serial port that you are using to communicate with the computer. Then (without changing anything else) set a password you know. Investigate the binary/hex that went across the wire looking for some representation (ASCII/Unicode) of the password. I imagine there will be a single bit somewhere which indicates whether the password is set or not. Determine which this is (should be the only difference between a password set update and a regular update). Write a fair simple program which sets ONLY this bit on the chip to false(0).
Take it and get it tuned. Run your program to unset the password bit. Of course this is assuming the password checking smarts are in the tuning software. Otherwise the chip will ask you for the password when you try to unset the ``password set'' bit. Afraid my knowledge of electronics is severely limited so that might not even be possible. Pete? All?
