B1S1 02 Sensor (IIRC its MV or something, there are two different ones)
Injector Pulse Width
Ignition Timing Advance
Throttle Position Angle
Engine Coolant Temperature
Transmission Temperature (I think its actually called like transmission fluid temp or something)
Air Fuel Ratio
Intake Air Temperature
There are a few more that I usually log that I can't think of right now for some reason. But using just the ones I listed should give you PLENTY of info for basic tuning.
Hope that helps!

Yes, I'm thinking the ones on that list that i would ever try to tune without would be air-fuel ratio, and both of the fuel trim ones. Sometimes knowing what the computer is commanding for air-fuel ratio will tell you if you need to go rich or lean though. But I may pull those 3 parameters off of the config file I use on the GTP.
MAF frequency is definately a good one, and one that I have never logged before. Don't know why though. I guess I just never thought about it. I need to add that one to my list.
For some people removing intake air temperature might not be a bad idea either to speed it up, but that is what the happy **** uses to adjust timing and I would like to see what it is at so I can see what the actual timing is on that run compared to what it should be.
