Unlock smart, safe power from your 2023+ Dodge Hornet with the JB4 plug-and-play tuner from Nforcd. Designed for the 2.0L I4 Turbo and 1.3L I4 Turbo PHEV models, the JB4 delivers a significant step up in performance without an ECU flash. On a stock 2.0L Hornet running pump fuel, independent testing shows gains of up to 30 wheel horsepower and 80 wheel torque, with even stronger improvements available under the curve. The system integrates via CANbus for smooth, factory-like drivability and packs advanced features you will not find on basic tuning boxes.
- No ECU unlock required and compatible with locked ECUs, with a true plug-and-play harness for quick installation and removal
- On-the-fly in-dash map switching, with up to eight maps to suit different fuels and bolt-on modifications, including ethanol blends up to 30 percent
- Boost by gear for improved traction, progressive water/methanol support, plus built-in data logging and fault code read and clear
- Optional JB4 PRO Bluetooth connection for iOS and Android to monitor parameters, adjust maps, and install free firmware updates
- Not VIN-locked, retains factory safety systems and driving modes, and fuel economy remains unchanged during normal driving
- Rugged billet aluminium housing, made in the USA, with a 5-year warranty; 91 octane fuel or better recommended for performance gains
