I've got a 2011 Kawasaki brute Force 750i and I was wondering if an ECU out of a 20/20 or other models would work cuz mine's bad just need to know what year models I can use in my bf

 

Go to one of the on-line parts sellers, look up the part number for your year ECU and then look up the part number for whatever year/model ECU you are wanting to fit. If numbers are the same the part will fit, if numbers are different, it probably won't.
