help, driveability issues with logs

[throthaduece85]

Im having stalling and cutout issues. Cold start is rough too. I did three logs, one of idling for 30 sec, one of revving 1500-2000-2500, and then light load accel in 4th from 2-4k. No WOT stuff. I think I have a maf issue and a lean issue but am not sure how normal stuff looks like. this is on e85.

To those who can decipher the logs, is this something that a tune revision can fix or is it a mechanical error/install error?

Logs show 35-50% lean with NO O2 correction.
If I had to guess, I'd say you were running the wrong tune (tune for gasoline maybe).

I'm no pro, but STFT's are not working. What kind of tune is this? Startup tune? Final tune?

startup tune. the tune was labeled e85. I swore I read somewhere that after 10 tune file changes in an x3 it can revert back to its first. I got the tuner from bama, then they did a revision for the exhaust, then went to AED for his NA tune which had a few revisions. Is there a way to determine if this occurred?

They are referring to the 10th spot on the sct device. Don't use that spot. Replace 1-9.

ok, ive only used spots 1-3. just heard back from tuner tho, I had requested both e85 and 93 tunes. I filled the tank with e85 when doing the fuel system and didn't know they wanted to start on 93. looks like shauns guess was right
