So, I know the previous owner of my 2012 ZX had the ECU flashed, but don't know the specifics ie who did it, when etc. I know it's been flashed because I can shut off the KTRAC and it remains off when turning the bike off and back on again. I also know that the American models were restricted as opposed to European models. So, my question is: Does the ECU flash return the bike to European specs, or something more? I know there are "other" mods such as the KTRAC but from a purely power/performance standpoint, does the flash match, or exceed European model specs?
