I have no idea why there are so many bad reviews, maybe I'm lucky? Mine works fine on my 2006 Hayabusa. Be sure to attach with Velcro or tape to reduce vibration. Vibration kills small electronics. But everything works great. You will need 3 taps (size 22-18 AWG) for installation. Red is the switched power supply, black is chassis ground, green is the RPM signal. You can usually use the wires on the dash, which is what I did. All settings work well and are easy to understand to make changes *5/5 stars for me, I have no complaints*
