Data logging

[Musa007]

Hello

I've tuning cars for a year now. Only stage 1, EGR and DPF. Mostly diesel stage 1 and VAG. My question is what data do I need to log cars and to see if they OK?

With what tool can I do this best? Autel, Launch, ..

For VAG use VCDS

Yes, I buy files from very good tuner. Never needed logging but I want to write my own files soon.
