Description
Unlock your Ford Maverick or Mondeo’s full performance potential with the JB4 Tuner, the ultimate plug-and-play solution for turbocharged 2.0L EcoBoost engines. Delivering up to 50whp and 70wtq on a stock vehicle, the JB4 boosts acceleration and power without the risks associated with ECU flashing.
Discrete, Fully Reversible Installation
The JB4 connects to two easily accessible sensors in the engine bay and works with your factory ECU to safely remap boost, timing, and fueling. Unlike flash remaps, the JB4 is fully removable and leaves your vehicle unaware it is producing extra power. Fuel efficiency is maintained during normal driving, and all driving modes, including towing, remain fully compatible.
Advanced CANbus Integration
The JB4 leverages full CANbus functionality to collect real-time engine data directly from the ECU. This includes pedal position, throttle input, timing advance, air/fuel ratio, engine knock, fuel trims, gear selection, and more. This enables highly precise tuning, ensuring smooth, consistent power delivery with minimal turbo lag. Tuners without CANbus cannot access or integrate this critical data in real time, making JB4 the superior choice for performance tuning.
Versatile Tuning Maps
The JB4 includes multiple pre-configured maps for varying fuels and performance preferences:
- Map0: Fully disable JB4
- Map1: +3.5psi peak (default, 91+ octane)
- Map2: +3.5psi peak, less top-end taper
- Map3: +4psi peak, 93+ octane or modified vehicles
- Map4: +6psi peak, 30% E85 mixture
- Map5: +7psi peak, 30% E85 or unleaded race fuel
- Map6: User-customizable map
- Map7: VALET mode / WMI (Water/Methanol Injection) tuning
