Hey guys, I’m new to this forum.

I plan to build the first-ever CLA 250 C118 Time Attack race car. Many aftermarket parts for BMW but unfortunately none for Benz c118.

I want to install a standalone Transmission Control Unit (TCU) or Gearbox Control Unit (GCU) to work with the OEM TCU to control the DCT Sequential Shifter and CAN keypad. Something like this:

Additionally, I want to install a hydraulic handbrake.

here’s the plan how the cockpit will looks like

HTG has a GCU that works with the BMW DCT gearbox, but unfortunately, they don’t know if it supports the Benz C118 or not.
and to install hydraulic handbrake, let’s say I use 2 brake master cylinders, how to make it works with the ECU?

Please share any insights if you know how to make it work.

Thanks!
