SDL3 Gear display with DCT box

Looked through the manual but had no joy... :shock:

Basically I'm converting my R32 GTR to DCT using Getrag box from BMW M2. I will be using the CANTCU controller and wonder if I can use the large central digit to provide gear selected.

I know I can do this using the gear ratio Vs speed formula but can the SDL use the display output from the TCU controller to directly show it on the dash? Would seem the most sensible and 'correct' method for displaying gear... :D

TT

Hi,

What format is the data out of the TCU in? If it is a voltage then you could map gear position against the voltage, or if it is a CAN message then the CAN messages could be read and used.
