Well established as a tuning solution for Stage 1 upgrades like exhaust systems and air intakes, the FP4 Tuner is now ready to embark on a rollout of Stage 2 FP4 maps for Screamin’ Eagle (SE) street legal camshafts.

Available now in the FP4 app, owners of 2021 and later Milwaukee-Eight (M8) 114 cubic inch air-cooled Touring models can select maps for SE Torque and Power camshafts paired with Vance & Hines exhaust and air intake upgrades using the drop down menus for selecting their map.

This initial rollout will be followed by maps for the same camshafts on 114 cubic inch Twin Cooled Touring models as well as 117 cubic inch Touring models for the SE Power camshaft.

M8 Softail models are also planned for map development for these same SE street legal camshafts. In total, the development plan will cover all standard M8 107, 114 and 117 cubic inch engines for Touring and Softail models compatible with the SE Torque and/or Power camshafts.

With its state-of-the-art Bluetooth enabled app-driven technology, FP4 empowers you to do 100% of your tuning from the palm of your hand, all while maintaining 49-state emissions compliance and thereby keeping your Harley-Davidson factory warranty intact.
