Need more info than what you have posted to get a picture as how the car is runing.
You said these #s are WOT. Did you verify that these LTFT...and other #s are with fuel Cell 22 indicating?
Cell 22 (fuel cells can be monitored by your Auto tap) is your WOT and assuming that your LTFTs are positive as you indicated, would mean that your other cells are correcting for about a 3% lean condition (positive trims mean more fuel added to correct lean condition). This would make your WOT trim to also move to a positive # and make your WOT a bit richer.
However, you also show your STFTs are pushing about the same # except in the other direction (negative). So I don't think this data is from your WOT, since STFTs remain at 0 during WOT.
What this data show, is that during the drive/load that the data comes from, the STFTs were trying to adjust your LTFTs to be near 0. Which is a good thing. This happens all the time and normal.
The RPM is way up there, indicating WOT, but it is possible that the throttle was just lifted at that point and the car had come out of fuel cell 22. You should make sure that this bit of data is from cell 22. If you don't have fuel cell data, then look at your throttle posision angle, which I hope you recorded also. In short, you should at least be checking the following with autotap:
Air Fuel Ratio (this is what the program ask the computer to achive, not what the actual mixture is)
Engine Coolant temp.
Fuel Trim Cell
Ignition Timing Advance
Intake Air Temp
Injector Pulse Width Average B1
Injector Pulse Width Average B2
Mass Air Flow Rate
Mass Air Flow Raw Input Frequency
O2 Sensor B1S1 (mV)
O2 Sensor B2S1 (mV)
Throttle Position Angle
Total Misfire Current Count
Once you have the above data. There are number of Forum members who can help you with what is the direction to go, before your dyno day (to set everthing else up well before your dyno run). You need data from normal driving condition in freeway speeds and various loads to get a good idea what your fuel trims are doing with different fuel cells, followed by some good old WOT/100% load #s and red line it in every gear (maybe not in 5th if not possible due to road limitaions). You dump all that data in a spread sheet program of your choice and analyze, analyze, analyze some more.....then adjust and verify. You get the picture.
Finaly once on Dyno, you will be only tuning the PE circuit which is only for the WOT conditions and best tuned on the dyno, with all your other fuel trims adjusted based on your previous above data to be near 0.
Sorry no easy answer when it comes to tuning. But I hope the above is a start for you.
