Fuelpak FP4 4+

Not sure when the FP4 has come out. I’ve had it for about 6 months give or take. I like the Vance and Hines brand but this tuner is very disappointing. Unless you’re planning to run an ALL Vance & Hines stage 1 then this tuner is not for you. I don’t think the tuner is the issue to everyone’s problems. I think the application itself is pretty worthless. I have to leave my screen on in order to be able and stay connected to the app(assuming you have a phone mount). If your screen locks then more than likely you have gotten disconnected. I’ve tried using the Auto Tune and don’t get the results you look for. The gauges displayed on the FP4 are worthless. Says my fuel economy is 1742miles to empty. Says I only have 1HP and 1Torque when accelerating. Luckily I’m not one to use the app as I ride. But I can see everybody’s frustrations. I hope this app gets better soon. I’ve been fortunate my motorcycle has been running fine. Atleast I believe it is. Not once has the FP4 given me any trouble codes to tell me otherwise even tho I’m running slip ons with a cat delete…

I bought this tuner with high hopes after having experience with the fp3. The app is horrible. It constantly disconnects which makes it basically worthless. There are many other issues that I don’t have time to write out. It did flash and tune the bike but you can pay someone 150 bucks to flash your ecm if needed. I was paying for the tune and all the features of the app and did not receive that. I also called customer service and they told me that’s just how it is and not much that can be done because the tuner is already paired with the bike. Do yourself a favor and save the 500 bucks. Go with dynojet or just have your ecm flashed.

I’m writing a review because some of this other reviews terrified me…LOL. The app works fine. The only option you get to choose for your map is the exhaust (cause all maps are designed around a “high flow” intake. There are plenty of manufacturers to choose from besides V&H. I had no issues with downloads/uploads, my cruise control still works fine (saw that in another review), and the ability to clear ECU codes is nice. The FP4 is a neutered FP3. No app will make the FP4 better. With that said, the V&H time really smoothed out the bike. I hated the stock throttle. That’s why I bought the FP4. It’s much better now.
