This page contains info related to the Suzuki GSXR Scluster decoder. The decoder is used to calibrate the TPS sensor (in Dealer Mode) and read ECU Trouble Codes, when the original instrument cluster is not installed. The data can be viewed by connecting a laptop to the Scluster decoder via a USB port. The SCluster code was written in assembly code (not an Arduino sketch) that is uploaded directly to the Nano. The code does not interfere with the bootloader, so you can use the Arduino IDE to overwrite with a new sketch at any time...
The Scluster Decoder project would not have been possible without the amazing work done by JoE on the TLPlanet.com forum. His research on the protocol used by the GSXR instrumentation cluster was the starting point for this whole project…
Hat’s off to you JoE and many thanks!!!
