Yes that is correct, It's a bit different to the power tuner.
To use mine I connect it to the bike then I plug the 12 volts power supply in to it, select the desired function ie CO
It will then ask for the mode button to be pressed and then the ignition to be turned on, once that is completed you can adjust the CO level.
Today i got myt Yamaha Fi (90890-03182) tool and it wont do anything,it shows only RPM.So only tool that will fit is that expensive new tool.90890-03215
