        Rated 4 out of 5 by from Well packaged, quality is there Bought the FP4 in the winter and only just did the download to my 14 Rushmore Ultra 103 HO. I was intimidated with the tech it proved to be very easy and intuitive. Quality. I haven't yet completed my auto tune but initially my idle is better and there is a throttle response advance. Be aware of that. It's a bit pricey but what isn't these days.

        Rated 4 out of 5 by from Nice but call the helpline This unit seems easy to install but the instructions are a bit confusing. First I had to copy the QR code and download the instructions. I then printed them off. I was following the instructions and got into the auto-tune section when I started running into problems. I called the help line and was informed that I didn’t need to go into that section. And I now have the (P) indicator light on in my dash which is caused by a faulty ground wire with flashing the ECU. The best advice I can give is to call the helpline before getting too far into the following the instructions. Now that I have it properly installed, my bike is running a lot better and smoother.

        Rated 3 out of 5 by from Decent. I like the interface and using the software while riding to display rpm and speed without having to look down at my bike. I don't like that it's air fuel ratios are fixed.

        Rated 5 out of 5 by from Fp4 Had a couple of problems loading a map at first, contacted V&H and got it resolved quickly. Bike runs good now and no more decel pop.

        Rated 5 out of 5 by from Great, just expensive The apple of tuners. Plug and play and worked amazingly well. Have a 2014 Sportster 883 with Vance and Hines short shots and a cold air intake. Would highly recommend but god it's expensive. Based on my research there is nothing like it on the market, but I could be wrong. Lots of features too that 95 percent of people won't use but fun to analyze data.

        Rated 2 out of 5 by from Won’t flash from iPhone. Won’t ‘flash an map’ out of the box on twincam Harley with iPhone. They say there will be an iOS update to fix this, but it’s been several weeks with no update; the last update was a year ago. The work-around is to pull the accessory fuse, which requires some disassembly. Also doesn’t recover well from a dropped Bluetooth connection. Overall not good user experience for a non-returnable $600 part.
