Fuelpak FP4

The app needs some work - it doesn’t stay connected in the sensor tab

Crashes every time you try to use the app. Have a brand new iPhone, redownloaded the app, tried multiple things. Horrible product don’t bother.

This tuner is awesome. Totally love the features and control you get with this app. I thought my ‘23 was running well but decided to give it a tune. Wow. Now it is even better. Well done Vance & Hines! Thanks for an awesome product!

Installed on my 2023 SG…… waste of money 100%. I gave it to my cat and now he smacks it around the house. I will never by another thing from V&H. I hope the project manager and the entire team got fired for this scam.

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.

If you’re just doing a quick intake exhaust this works well. If you have cruise control just know every time you touch your tune your CC will stop working and off to dealer to fork over $100 to have it re-enabled. Add option to enable CC when you load and easy 4 star, no cruise and bolt ons it does the job. The interface for everything else sometime works or like other state just get garbage data back. This tuner should be a 50$ tuner because it’s only good for one thing, loading the map

Realmente no vote su dinero en este dispositivo. Tiene un sin numeros de errores y en servicio al cliente solo dicen que están trabajando con los problemas pero de esto van meses. Lo irónico es que siguen vendiendo el producto a sabiendas que no funciona adecuadamente. No lo recomiendo y no sirve. Tampoco es barato!

I have had 3 FP3’s this version does not meet muster as far as I’m concerned. If I had known then what I know now I wouldn’t.

I’ve had the FP4 on my RGS for about 6months now with no issue, I always updated and flashed on wifi but have done a firmware update on cellular once and had no issue. I’ve even used the optimize settings to adjust throttle response and idle RPM. Ive done the stage 2 torque upgrade and had no issue with the FP4. I’ve called support and they were helpful and knowledgeable. My only complaint would be the lack of options, I have Tab Performane 2n2 with V&H Hi Output slip ons and my only option is V&H Hi Output slip ons with V&H Dresser Duels. They only have stock HD and V&H options. Runs good with the tune.

Just received it. Firmware and app up to date. Pretends to connect but when searching for a map, no options are available for exhaust, fuel, engine. Just states to “CHOSE”. ECU can be rad or uploaded because no “FP4” found. I had a previous FP3 and it was fantastic. I’m on the fence with what to do. For that cost, no issue should occur out of the box.
