I've searched for well over an hour and couldn't find anything. My Low, mid, and high LTFTs are always showing the exact same thing. This seemed to happen after I changed the formulas. Here's my Evoscan (2.0) data stuff:

Display="Fuel Trim Low (LTFT)" LogReference="FuelTrim_Low" RequestID="0C" Eval="(0.1961*x)-25" Unit="%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-50" GaugeMax="50" ChartMin="-50" ChartMax="50" ScalingFactor="1" Notes="Long Term Fuel Trim - Low" Priority="1" Visible="False" />

Display="Fuel Trim Mid (LTFT)" LogReference="FuelTrim_Mid" RequestID="0D" Eval="(0.1961*x)-25" Unit="%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-50" GaugeMax="50" ChartMin="-50" ChartMax="50" ScalingFactor="1" Notes="Long Term Fuel Trim - Mid" Priority="1" Visible="False" />

Display="Fuel Trim High (LTFT)" LogReference="FuelTrim_High" RequestID="0E" Eval="(0.1961*x)-25" Unit="%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-50" GaugeMax="50" ChartMin="-50" ChartMax="50" ScalingFactor="1" Notes="Long Term Fuel Trim - High" Priority="1" Visible="False" />

My STFT seems to work fine (it jumps all over the place anyways).

If anyone needs any more info, let me know. I can't seem to find anything wrong.

Am I missing something obvious or doing something wrong?

I had an instance where my trims would not change. The fix was to completely uninstall,reboot and reinstall Evoscan. I have no clue why other than it might have been a Vista thing.

Good Luck

I dont spend as much time worrying about the long term trims as I do short term at idle and cruise and you can watch/log those easy enough. I had that problem with 2.0 and v99 but 2.4 seems to have it fixed. Dont get me wrong it nice to see the numbers get closer and closer in the LTFT but they can change just idling realistically even if you thought they were "set".

Thanks guys. I will try the uninstall/reinstall. I'm mainly concerned about logging a correct value. The value that's set now is .101 or something close to that, but I'm not sure if that's a low or mid trim or if it's even a correct value. My STFT are all over the place (so are my idle afrs). As far as I can tell and hear I don't have any exhaust leaks to account for the large swings.
