LTFT question

[Broken041]

I have been out logging with the Atap. Good for me, nothing new to speak of really. But I have noticed this. And it makes me wonder. The LTFT's differ between bank 1 and bank 2. Not that this matters for the average, but.

Here's what I have.

10030.9 4685.7
785 Lines when in FTC 1-19

24.93 24.51
28 Lines of TPS > 99.5


Avg Intake Air Temp: 51.56913183
Avg Coolant Temp: 190.1414791

LFTF B1 12.77821656 avg for fuel trim cells 1-19
LFTF B2 5.969044586 avg for fuel trim cells 1-19
B1 & B2 9.373630573 avg LFTF for fuel trim cells 1-19

O2 B1S1 0.890357143 avg WOT B1S1
O2 B2S1 0.875357143 avg WOT B2S1
0.882857143 avg WOT O2's

KR: 0 occurrences (over 3 degrees)
#DIV/0! average KR (over 3 degrees)

Obviously a little on the lean side. But that might be expected running open headers right?

Anything that I should worry about since the LTFT are not close other to each other in comparison?

Just out of curiosity take out cells 1-5 and 17-19 and go with 6-14 cells and see what you get .... some of those other cells are idle cells and may be throwing off your numbers.... some data here on Smileys site to read http://smiley.tzo.com/fbody/atap/ look under FTCs :)

now - no you shouldn't see numbers that far off. they will not be exactly the same... but they should be close. perhaps a header leak somehwere?


ps - noticed you're an ohio neighbor ;)

In my opinion averaged across-the-board LTFTs don't
tell you squat (unless they're so whacked that you
can't miss it).

Get them all sorted into FTC "bins" and go bin-by-bin
looking at the trims' value.

From appearances, the thing is gross lean but the
trims lock in to make WOT relatively OK. Not where
you want to be, just surviving.
