Anybody?
What exactly is the problem? I don't see anything in the log that would tell me your maf is messed up.
According to my histograms my LTFTs are -5 and my STFTs are all over the place between -18 and +25.Quote:

I don't know how you guys tune these things, there are soooo many blank screens. You would freak if you looked at my tune and all the settings I can change. Sorry to rub it in...
PS: WTF does LNF stand for?
That's normal, the stft will fluctuate like that in some parts of acceleration/deceleration.Quote:

Thats the 2.0L direct injected turbo motor found in the solstice/sky/hhr/cobalt.Quote:

How do you shut off DFCO for tuning? it seems to be screwing up all my numbers.
Holy post raised from the dead batman. I was like... "Umm term asking about maf tuning, whats going on here"
If you don't want DFCO, 0 out the torque management inj disable table
I'm fairly new to all this and I know this is what they had to do on LSJ to get it dialed in but is this the right way to go about it for the LNF? Is there a better way to get clean results?
Screwing up what numbers? Like Ch1ck3n said http://www.hptuners.com/forum/showthread.php?t=28714
