New to logging... couple questions

[snowmansdsm09]

I just got my logger and I've been playin around with it.

I got my STFT almost to stick @ 0... I had to richen things up TONS
I was running -18 all the way across on my LO (safc) and now I'm running -2 @ 1k and work my way leaner.
The car feels so much stronger driving around... I figured my MPG's would go waaaay down but it actually got better for some reason. I added gas but get better gas mileage now??? Why is that?

I need help with these.....

I can't seem to find out how to record my run?
My Air Intake Temps are stuck on 80?
My LTFT will NOT go down to 0 ... the closest I got it was 2?

BTW I use tuner stein

I've read all the logging 101's... still don't see the answers to my ?'s...

Also I have the GM maf sensor so is that why my Intake Temps aren't showing up???

You're getting better gas mileage because you dont have to use as much throttle to get up to speed.

As you lean out your car you mileage will get better because you are using less fuel.

I know the Leaner your run the more gas mileage you are supposed to get...
But its opposite for me in this case...

I was runnin' -18% on my lo's... now I'm running way down in the single digits...
Getting better gas mileage and car feels really strong.

How do I record my runs??????
And how come my intake temps aren't showing up????
