Datalogger fuel trim problems

[Gula]

I just hooked up my Pocketlogger and was messing around with my low rpm AFC settings. I was using the fuel trim, but all day it has not changed once. My high is always 93 and my low and mid are stuck on 81. The O2 toggles nicely and the O2 trim is busy changing from 0 to 199 at times.
Any ideas why the trim doesn't change?

Thanks

I've heard of 1G's taking as long as a couple of days, depending on the driving. Try reseting the ecu and then adjust with your O2 trim.You may have to wait a while for them to correct. drive around nice and easy so the ecu stays in open loop mode.
