ok, so this is a 3rd gear pull.... i used my work scanner since i work at a car shop... its a genysis scanner that we use for diagnosis and stuff and it reads fuel trims and all that. now this scanner is beat up.... the connector isnt all that great but still connects but there's always a chance of it disconnecting. anyway. i was going to order me a pocket logger but i figured let me see if this scanner can let me see what the ecu is doing. first things first. Do i have all the information i need to tuned from my safcII or do i need something else like the numbers for stft bank 1 sensor 2... also as you guys can see that i have zero's at 2600 RPM and after... im thinking the scanner had a glitch.... i didnt have time to try another pull cause a 3rd gear pull isnt all that safe LOL... but i just wanted to show you guys here (and girls) and make sure that the scanner failed to give me readings... but the weird thing is that it still recorded the rpms but not the trims... any inputs? BTW right now im at -10 all across on my safcII and im at 16 psi on my evoIII
 
Umm I don't think you understand how logging works, the car doesn't use the Fuel Trims under WOT thats why they go to zero.

Log RPM, Timing, and your front o2.

You use your fuel trims at idle and while cruising to set your low throttle settings.

Also your high throttle should probably be around -15 and even that should be a little rich.
