there are 2 types of "software" updates, GS911 firmware update & PC Application update so the first question is which one are you referring to ?, the second question is whether you were using a web browser or the PC App & the 3rd question is whether you have downloaded & installed the GS911 WiFi utility & the PC App
Neither type of update would change ECUs on the bike, they only affect reading of info from the bike so the first step is to disconnect the GS911, close the PC Application (if using it) then plug the GS911 back in & do an AutoScan again
