4.2 Connecting to PC or Wheelbase
The MOZA HGP Shifter offers two primary connection methods:
- Direct to PC (USB): Use the provided USB-B to USB-A cable to connect the shifter directly to an available USB port on your computer.
- To MOZA Wheelbase (RJ11): If you have a compatible MOZA wheelbase (R3, R5, R9 V2 New Edition, R12, R16, R21), use the provided RJ11 cable to connect the shifter to the designated shifter port on your wheelbase. This allows for integrated control and power.
After connecting, ensure your MOZA Pit House software is updated to the latest version to recognize and configure the shifter.

5. Operating Instructions
5.1 H-Pattern Shifting
The MOZA HGP Shifter operates with a traditional H-pattern layout, providing seven forward gears and one reverse gear. Engage gears by moving the shifter knob into the desired position.

5.2 Engaging Reverse and 7th Gear
To prevent accidental engagement, both the Reverse (R) and 7th gears are locked. To select these gears, you must apply a downward pressure on the shifter knob while moving it into the R or 7th gear position. This mechanism ensures precise and intentional gear selection.

5.3 Intelligent Downshift Throttle Blip System
The MOZA HGP Shifter features an intelligent downshift throttle blip system that automatically matches engine RPM during downshifts. This system enhances vehicle balance and smoothness, especially during aggressive driving. This function is fully selectable and customizable within the MOZA Pit House software.
