The Cronus Zen Wheel Edition emulates a Logitech G29 with Force Feedback (FFB), and this is how the G29 buttons are mapped to a Logitech G27.
All the standard controller buttons have been mapped to the G27 Shifter and Wheel Paddles so you can navigate the PS4 menu without having to use a PS4 controller.
This is the layout of the Logitech G29. Note the Rocker and Dial (which is mapped to L4/L5 and R4/R5 on the G27).
To make following the remapped buttons easier, we've designed an overlay sticker for the G25 / G27 shifter. Click on the file below to download the uncompressed image. When printing set the size to 100% so that it fits perfectly to your Logitech G25/G27 shifter plate 👍
