/\ 05 you don't have to go into boost for it to count as a drive cycle . The ECU does its trims in closed loop . IE very light throttle situations .

can't see those logs ...

it could go back to where it was before . Good idea to monitor what is going on for a few days till you are sure it is stable .

to reset the map and fuel trims do i have to reflash the map or is it enough to do the "reset ecu" command that the accessport has?

hmm okay

i reset it again because it seemed as if the AFRs were climbing again even though i just reset the ECU. so this time it only took about less that 100 miles to screw with my AFRs! argghh!

I wonder if the timing has a temperature modifyer that is advancing from your base tune and leaning the mixture? The same volume of fuel ignited earlier is going to read leaner - and some (like the PFC) EMS' retard hot intake air (like on a dyno) vs. cooler air from the street. Just thought that might help any???? I don't know the AP well enough.

i did reflash it today =( i was just asking for the next time i have to do it since it seems like it might be a regular occurrence =(

i wonder if its fixable by adjusting the trims, i didnt know the trims affect the AFR so much...

How lean is it going now? It's leaning itself out on it's own much quicker now, too, huh? I know how you feel- mine does it too

^Yeah, it is. I haven't gotten my tune yet (hopefully soon.....) but it blows having to watch AFR's constantly. But it's the price you pay for doing an aftermarket turbo.

I think it is a multiplier issue... but I don't know which one. I don't think it is fuel since we are MAF-ed... but maybe timing affecting fuel? Anyone log timing at different temps?

BTW - from what Jeff said - fuel trims don't affect open loop any.
