It's really pretty simple. The hardest part of the whole installation is hiding the thing. It took me about 20 minutes to install,and start engine. Upload the particular map for what you have on your bike, (k&n filter,screamin eagles ect...) then hook it up to your bike. Now if you have a notebook pc,you can install it and then upload the map. one end snap's into your stock pcm,and the other into the pcr111. believe me,the differance with the pcr111,is like night and day!! The throttle response is unbelievable. If you have any problem's,just go to www.powercommander.com,and
you can view installation video's. I hope this help's you.
