HP Tuners
HP Tuners I know on hptuners forum they ask for a log of your driving and I don't know what all I would need. Right now my car is mostly stock and gas mileage is horrible. I want to show them how its running but I'm not sure what all I need to have monitored and how to drive for this. Any ideas?
There're some things you always want -
RPM, MPH, TPS, MAP, MAF freq, MAF airflow, Dynamic
Airflow, Dynamic Cylinder Air, Spark Advance, KR, Knock
Learn Factor, Bank 1 LTFT, STFT and O2 sensor voltage.
I usually ignore Bank 2 but if you suspected an imbalance
you could log that.
Save your .cfg file too and put it up with the logs where
you do that; helps people look at it the same way you are.

Thanks for the help. What about as I'm actually logging. I assume I need to warm the car up and then how do I drive when logging?

How you drive depends on what you're trying to tune.
For your mileage issue, I'd suggest a decent amount of 30-60mph+ driving... 25mi or so is a good start if you don't have a wideband O2.
