you might wanna go check the first posts though and check that, its been a while since i cared about the AP stuff since its senseless for me to be keeping up with updates for the next couple months...

 

/\ 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 .

 

right after i reflashed today though the trims were not all over the place. the LTFT is settled already around 0. how much more adjustment can it make?

 

here are the data logs

when it was running normally and with safe AFR values

when it went lean

right after i reset and reflashed the pcm with the same map

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 .

 

konig - rapidshare sucks. if you know how to use an ftp server i can give you some access.

 

ftp ftw

flashfxp is a very simple yet effective client

 

simplicity is the key!

 

how would i do that?

 

konig, e-mail me the logs and I'll throw them up on a ftp

email sent!

 

got it - check your e-mail.

 

thanks to alzors for hosting them for me! =)

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?

 

I would say either way would work.

 

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!

 

man that sucks. try reflashing the map instead to see if it makes a difference.

 

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

 

man, I hope my final tune from MM is not going to do this....what a PITA

 

^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.

 

it went from mid to high 11's to low to mid 12's, but im sure it would keep getting higher eventually =/

 

if it is a timing issue then is it fixable?
