[QUOTE="WhiTriCobra, post: 15582855, member: 77590"] That's cool and shocking they asked for one. Datalogging is definitely useful and I recommend learning what each parameter means or what it's doing. That way if you catch something that they tuner misses or something you don't like, you'll know. Or when troubleshooting. one example; I didn't know my throttle body was messed up until I saw the throttle angle actual vs throttle angel desired. Numbers were way off. Put the stocker back on and numbers were almost identical. Car even felt better after that. Or knock sensor. Do you think a +3 is good or a -3 is good? A lot would think +3 is good and it's adding but it's opposite. -3 means the car is feeling good and adding timing. +3 could indicate knock and it's pull 3 degrees. [/QUOTE]
