Raising from two stars to four stars due to customer support. First unit malfunctioned making by it useless. V&H next day aired a new one to me pre programmed with my map. There are still some functions they could fix and the unit does not come with anything that explains all you can do or monitor with the Fuelpak. Your left to search user blogs from fellow riders to see what they have done. It will map your bike. You can tweak settings after it’s mapped. Online videos from V&H not very impressive. I’m happy with it, I think it could be much better with a little development.

The MISSING LINK for your HD!

I’ve done very few reviews, honestly, I’m not impressed with much these days. Rode bikes for 47 years and Harley’s for more than a few of those. This FP3 tuner from V&H combines all the little details that make my bike, truly mine! From the quicker throttle response, to the “warm up RPM” setting, custom red line threshold, everything I ever wanted to do to my bike, I can do myself, from my iPhone! If you get one time for Christmas this year, make it the FP3! Simply put, it pulls the entire bike together, tighter, more fun experience riding. Each tune can be set for the specific ride. Be safe and Ride On, Friend!

Good... but limited tuner

For a basic stage one tune it’s really all you need. But if you plan on going further it’s limited. It’s glitchy sometimes, especially with the auto tune but what do you expect when it’s used through your phone. They really need to put out a good manual for this product. But like I said it’s a stage one tuner and that’s really all they expect it to be and why I say it’s a basic tuner. I wish it had the ability to data log, but since it don't you’re really flying blind. IMO spend a few xtra bucks and get a TTS. So much more versatile.
