I have a early production 2013 ZX6R that I bought used. When starting it cold it may take 2-4 attempts until the engine will start warming up instead of dropping rpms too low and stalling out. I have done a lot of research and this appears to be an ECU issue. I have found a good price on a 2015 ECU so my question is, will my 13 ZX6R take the 15 ECU they have the same exact model numbers 21175-0812. Any help is greatly appreciated!
