I got in a TL866A programmer with the complete adapter set,   pulled the flash chip from my dead TruePosition, and dumped the chip.   Success first time!   Now to go through the ROM dump and see what hidden goodies there are. 

A quick look seems to show commands for setting  Kalman filter parameters and antenna (?) attenuation. Also a GAIN command (maybe EFC gain or antenna gain).  There seems to lots of debug modes in it.
