Wideband 02 Data Logging ?

Alright ive looked around trying to find my answer and just cant. I have a nelson mail order tune and would like to futher my tune as much as i can so i would like to send a data log to them to make sure everything is right where it should be. What is the best and easyest way to do this? i am new to the tuneing world ill admit i dont know much but id like to learn!

If your mods are just in your sig Allen will have your tune 99.9999% correct....but if you feel the need you could buy hp tuners and log and email him that and he can see what's going on..
