Depends on what your tuning but I would say thats pretty good. I dont log air/fuel as thats just what the computer commands, not what you acctually are getting. The only other one I would add is MAF Frequency. The less fields you have the faster the updates. You only need these 2 if you want to figure out how much boost your getting

Barometric Pressure
Manifold Absolute Pressure

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.
