Tuning

With systems like the Hondata, how difficult is it to tune it? I assume there's some type on interface, but how easy is it to use? I'd assume a shop with a dyno would be the best way, but I was just curious if anyone with a Hondata system tunes it themselves.

you can do it yourself but you really need someone who knows what there doing

I have read most of Hondata's tech articles entailing the tuning process of their system. It seems that while yes, tuning by yourself is doable, the process still requires the use of a dyno with a wideband oxygen sensor. You do have to spend a little bit of time to sit down and learn the fundamentals of tuning. It's no VAFC.
