Why develop this adapter？
The new generation of Porsche steering wheels, inspired by the 918 Spyder, features a modular design that allows for personalized options and advanced functionality.
Which style do you prefer?
However, these new wheels use the LIN BUS 2.0 protocol to communicate with the steering control module, which is different from older wheels. Directly installing a new wheel on an older Porsche results in multifunction buttons, key lights, and heating functions not working. This challenge led us to develop the GPS Adapter.
The development process included:
1. Analyzing raw vehicle communication data from both old and new steering wheels, comparing protocols and data bits.
2. Designing and implementing the adapter circuit, identifying original sockets and plugs, and ensuring a one-to-one connection for easy installation.
3. Selecting an STM8AF automotive MCU to process LIN BUS data and convert additional signals.
4. Conducting six months of real-world vehicle testing and optimization. For example, at an ambient temperature of 27°C, the hottest chip—the LIN BUS transceiver—reached only 39.3°C.
My 2014 Panamera was the first test vehicle for the prototype, shown in the photo below.
On June 1, 2017, we released the first stable version of the adapter. We continue to work on circuit and software optimization.
New cases and updated circuits are scheduled to ship in early July.
Currently, we are also working on MODE SWITCH synchronization with the center console for 991.1/981/958.1 models. Thank you to all our customers for your trust and support during this development process.
