How many people here datalog?
I'm using TMO logger and TunerStein for the laptop. For my Palm m130 I'm using Palm'N'Stein and MMCd.
I am having a problem with bad gas mileage but the fuel trims look good and both O2's are cycling no codes are showing up. I'm thinking it is the ECU caps but I haven't had a chance to pull the ECU to check.

I double checked them with TMO on the way home from work.
High Med Low 114 100 81
It was (last time I logged) 125 110 115
So my idle is running pig rich. I show no codes so I wonder if an injector or two are on their way out.
I think I'm going to reset the ECU, drive around and see what shows up.

Doh the Palm is dead 12V transformer into a 5V device. It doesn't even do a reset.
I'm still checking for the new trims.

I think I'm going to reset the ECU, drive around and see what shows up. There are other variables that greatly effect feul trims. Temperature and barometric pressure are 2 major things. Unfortunately, you don't have control of those. I find myself tinkering with the AFC all the time to compensate for these.

From a log I did this morning on the way to the car wash.
High Med Low 102 100 81
I think something is a miss for the low trim. It was 81 right after I reset the ECU. I think I'm going to try disconnecting the MAF and see how the trim is after another ECU reset. The temp and pressure output from the MAF does move around so I don't know if it really is a problem.
Kuettner told me I needed to replace it in January (I had the car in for recall at that time) but I thought they were just faking me. It wasn't fully plugged in when I looked under the hood.
I thought for idle that the ECU compensated for SAFC until the ECU gets what it wants.

Correct. The ECU is seening a very lean idel mixture and is adding feul to compensate.
Have you checked for boost leaks? Air comming in behind the MAS will also cause a lean mixture (no duh).
