I love that you can load a tune and log live data to create a custom tune. You can then save that and modify it also. It's like turning your bike on a real world dyno.

Doesnt work the way it was dreamed of
I would not use this for a final tune, it threw the tables off which led to backfires. spend the money on a real reputable tuner that will tune your bike. It gave me more headaches than what its worth.

Dynojet Auto Tune Kit For Power Vision For Harley
I love this thing, If you have an early TC with no o2 sensors and are upgrading intake, exhaust and cams this addition to your bike will help you dial the tune in. If you are like me and do not want to rely on others to tune your bike or can't get to a dyno tuner, this is thay way to go, IMHO. You will however need to do research and understand how the motor works and what it needs.
