The LCD display is really only useful for data-logging and seeing real-time data from the inputs (AFR, RPM, TPS, InjDTY, etc.). You can calibrate the TPS value for the PCV/PC3 trhough it, and you can also switch map files IIRC, but no fine editing of maps or autotune tables. Still a damn useful display, though. :)
