ECU Swap

[Paul]

can you interchange an ECU from a GV250 to a GT250 to see if the GT runs??

GT came without one but I have a GV also.

Part number is 1 digit different

Thanks

Hey.
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 🤞

The one digit is all important.

Hyosung used a different ECU for just about every variant of bike and major changes to them in 2012.

So it depends on what the bike is, what year it is and you really need to post the ECU number, ie:

GV650 EFI MODEL PART NO: 32900H89800 , 32900H89300

EFI GT250 GT250R Delphi: 32900HB8600

GT250 GT250R 32900H88600 , 32900HR8600

EFI GV250 delphi 32900HB8400

GT650 GT650R GT650S EFI MODEL 32900H89300 32900H89310 32900H89300

If its delphi ecu it should be fine..
