somewhat.... instead of having 4K of NVSRAM mapped from 2000-2FFF, they replace their entire PROM with it... and program it over the ALDL circuit using customized ALDL commands... i believe they made modes 11/12/13, something like that.
much like OBD2, they also only have the calibration changed when uploading the new tune so that they don't have the possibility of corrupting the algorithm.

I'm content with plugging and unplugging an EEPROM. But it's neat to see what others are up to!
