They think it's cool/useful to be able to read any codes the car may have even if it's not caused by the 'tune'. The Stage 1 used to support the usb cable, but they have since discontinued the output, it's only on stage 2 now.
Guess having it on stage 1 made stage 2 less desirable for people that kept it in map 1.
