I'm completely new to obd2 tuning
I did street tuning on obd1 Honda using crome hondata Neptune so I'm familiar with editing
after some research I gathered some stuff
tactrix hardware. to load the reflash file to ecu or read the file from ecu or does it only write reflash file?
pcm flash is for checksum and flashing the bin file after editing
bit edit winols ecmtitanium are the actual bin editors ?

how are the files stored? the stock ecu dumps are they in .bin format or something else?
will all those softwares be able to read same format file?

I don't understand how it all works if anyone could explain some details to me that would be awesome

I know there are hondata and ktuner available for TSX but they lock you to a single ecu and I'm not cool with that since I have multiple cars
