Vance & Hines announced the FP4, the next generation of its industry-leading engine control module (ECM) flash tuning products. The FP4 features an all-new circuit board, case, firmware and mobile app, all of which were designed and manufactured in Santa Fe Springs, California. The FP4 brings greater control and optimum performance tuning to Harley-Davidson Touring and Softail models because it’s the only app-driven tuner in the market.

“We know riders want the best setup for their Harley-Davidson, just like we do for our race bikes,” said Vance & Hines President Mike Kennedy. “Think about it, the bike’s stock ECM is set for a stock exhaust and factory air intake. When you make changes, like adding a different exhaust or air intake, you need the right tune to get the full performance potential out of your engine.”
The heart of the Vance & Hines FP4 is the ability to dial-in the motorcycle’s ECM tune to match the performance upgrades that a rider adds to their motorcycle, such as an aftermarket exhaust system and a high flow air intake. Owners of the FP4 may choose from a vast library of Vance & Hines maps created in the company’s dyno-tuning lab in California. Vance & Hines maps are model-specific and are created using actual parts on real motorcycles, not projections made from previous tests. Owners are able to further develop those maps with a number of customization options found in the FP4 app.
The Vance & Hines FP4 unit has a slimmer and smaller case and a longer wiring harness than its predecessor, Fuelpak FP3, allowing more options for locating the hardware on the motorcycle. It features simplified LEDs on the unit, which display the communication between the unit and the bike. The FP4 also uses the new red OBD II connector, which is now standard on 2021 and 2022 Harley-Davidson Touring and Softail models.
The Vance & Hines FP4’s smartphone app is one of the significantly upgraded features of the device. It has a new look, is easier to use and is faster than ever before. The user experience is vastly improved with a redesigned navigation bar, giving easy access to the FP4’s core tuning functions. The Live Data capability of the app includes a new gauge layout and delivers more data to the rider than any other ECM tuner on the market.
