The way to tackle data collection depends on whether you are proficient in electronics or not. In either case you will need to download a program freely available on the internet from https://netcult.ch/elmue/HUD%20ECU%20Hacker/. This help file is a must read. Further down you will find a link from where to download the actual program. This program is very professionally written and complete. Its only drawback for me is that is works only in windows and since I am a Linux user I opted to write my own using python and that help file.
In terms of hardware you can use the Blue interface cheaply available from Ebay or Aliexpress (search for VAG KKL; cost around €5) and solder a 3 wire wires from inside the interface to a 4 wire connector which goes on the Hyosung. This is an easy job. I had ordered this interface but since it takes 4 or 5 weeks for items from China to come to me, I opted to build my own in the meantime using a standard USB to Serial converter I had around. This would be the black thing to the left of the picture. Both work well.
