There's only a couple possibilities why this is happening. Either the o2 sensor isn't wired up correctly (I have a swapped car) or I accidentely disabled the front o2 through the perephery files. Here is a log and my tune and maybe someone can find a hint.

Here's my log from MitsuLogger:

Here's my ECUFlash tune:

try that copy that into ur evoscan xml

 

Mine were the exact same other than the log reference name which I don't think matters. On the next page of that thread is the syntax for evoscan and mine were the same as well other than the eval function for "ltft_low"

 

sorry wrong xml its suppose to be this

<DataListItem DataLog="Y" Color="" Display="LT Fuel Trim Low" LogReference="LTFT_Low" RequestID="0C" Eval="0.1953125*x-25" Unit="%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-13" GaugeMax="13" ChartMin="-13" ChartMax="13" ScalingFactor="1" Notes="" Priority="1" Visible="False" />
<DataListItem DataLog="Y" Color="" Display="LT Fuel Trim Mid" LogReference="LTFT_Mid" RequestID="0D" Eval="0.1953125*x-25" Unit="%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-13" GaugeMax="13" ChartMin="-13" ChartMax="13" ScalingFactor="1" Notes="" Priority="1" Visible="False" />
<DataListItem DataLog="Y" Color="" Display="ST Fuel Trim" LogReference="STFT" RequestID="0F" Eval="0.1953125*x-25" Unit="%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-25" GaugeMax="25" ChartMin="0" ChartMax="200" ScalingFactor="1" Notes="" Priority="1" Visible="False" />

that made my fuel trims log up past that into the evoscan xml file and open evoscan and you will see them uncheck the originals and select those there is no ltft for high tho. also i can look at your log right now if your if your o2 sensor bounces around you should be getting a fuel trim i had the same prob this fixed it for me.

 

off topic-
also whats a 2000 eclipse gsx? lol. i thought 99 was the last yr.

 

did you disable closed loop? if so, that would be the cause, must enable closed loop and the trims will start doing their thing!

 

It's my own little creation...

I don't think I did. Sorry I'm like 3 days new to learning this stuff..

 

o2 senso seems ok i guess... umm once it warms up.. try the xml i gave you and let me know....

 

Nice Vids Boston!

 

You don't happen to have a low temp thermostat do you? What's your water temp get up to?

 

No I don't think so. At idle the coolant temp cycles around 190.
