SAFC tuning and Logger

[SinaiTSi]

I have a 2g maf and 660s in my 1g with an SAFC. I'm trying to get a decent tune for the time being before I get a chip in. My problem is that I'm trying to tune with my palm logger and I'm a little confused on a few things. Tuning guides I've read say that for low throttle driving you should tune with you the lower fuel trims. On my logger (I have MMCD) I have FTRL, FTRM, FTRH. But they just stay constant, nothing ever changes with any of them. So when I'm trying to tune FTRL, just reads 139% the whole time. Now, I also have FT02, this does change, and I'm trying to get it at 100%. Only problem with this is that I'm not sure if I should be tuning with the FT02 for low throttle driving. Also, at like 2500 RPM, my SAFC is set on 0 correction and it says I'm really lean (167% FT02). Is that possible with 660s? Any help is appreciated.

I've already read both of those. I was just having trouble with my fuel trims, I just needed to reset my ecu. Thanks though.

Glad you got it resolved one way or another. I have to look at that page every time I fiddle with fuel trim tuning just to remember whether 140 is too lean or too rich, so I figured I'd cut out the middleman and link them.
