JB4 Tuner

This plug-and-play device attaches directly to your gas pedal, allowing for immediate remapping and improved throttle response. Users can seamlessly switch between stock, stage 1, stage 2, and stage 3 performance curves while on the move. Each mode can be further refined using simple up or down adjustment buttons integrated into the device itself. Installation and removal are straightforward, taking only a few minutes. The BMS Pedal Tuner operates independently of other vehicle modifications and is fully compatible with systems such as the JB4. To calibrate the system after installation, press and hold the '+' and '-' buttons simultaneously until all lights flash. Then, fully depress the gas pedal a couple of times; the status lights should move to the right as the pedal is pressed. Finally, press and hold the stage selector button to save the calibration and complete the setup. Settings are indicated by light colors: a white square light signifies Stock mode, green indicates Stage 1, orange/red is Stage 2, and a solid red light represents Stage 3. The round '+' and '-' lights are used for fine-tuning adjustments, with '+' increasing sensitivity and '-' decreasing it. The product comes with a lifetime replacement program.
