Hey guys got a question for yah, I already have a dsp5, I am trying to do my own tuning. My question is the os number. I basically saved my first tune and went to convert operating system number and it doesn't give me the option to do dsp2 or dsp5, under that tab it is blank, but under the calibration window it says os id is v6 indicating the stock file I loaded was already dsp5 if im correct. How do I load my own files into this? Thanks.
