I know for a fact when it says S&T and other says KRmotors with a different branding , it may not work simply we dont expect every sensor on bike to act with that ECU n the dash.

I have not heard a lot of success stories about mixing GV n GT ECU but *some* 650 bikes are known to do that.

250 Carby & GV250 Carby dont allow CDI mixing, i know for sure and harness is NOT the same by a long shot

Your ECUs is best to match the bike its meant for 🤞
