That's cool I may end up just buying my own tuner. Thanks for the response
I just do 96-03. I haven't tried tuning a 04 with my tuner. I have used another persons tuner to tune one though but i think my hardware version doesn't support the 04+

what year and model car do you have? adjusting the fans is a quick fix in the pcm.
I was just reading a post about you tuning and was wondering if you still do it? I'm having problems with my cooling fans kicking in too late my mechanic told me its in the PCM.
