I must be missing something simple with the nefmoto data logger. I've got the tuning aspects pretty well figured out - I've made various tweaks to a couple tune files for my S4 without any issues. But the data logging I cannot figure out - I think all I'm missing is how to pull in the definition variables (or create my own). Could someone give me a quick run through of this?? I'd prefer to use the nefmoto software to log rather than my VAGCOM

Thanks and sorry for the stupid question - I've been driving myself crazy trying to figure this out and I'm sure I'm missing something very basic.
