I have been trying for days to get my actual lambda to meet requested.  I have been bumping the KRKTE up and I have been bumping up KFKHFM on the higher load areas.  The car runs REALLY lean in boost.  Can someone take a peek and let me know what you think, and possibly point me in a direction to fix the problem?

CSV LOG, ECUX LOG, and latest revision of my tune attached.

1) Consider using the filter option.

You are using 2nd gear, so set the filter to look for 2nd gear

2) Consider using 3rd gear

Your log isn't very long (time wise)

3) I don't see that you are running lean (compared to your req afr). Do you have a wideband?

Maybe I don't understand my log.  I was watching my O2 sensor voltages and they seem to et around .937ish at the lowest point.  I   thought that was around 13.xx af at peak load.  This is pretty much the trend in all my recent logs.  No matter how much I bump KRKTE or KHLFM (SP) it doesn't give me what I thought I was looking for.

Changes I have made that affect afr.....I think it was just the screen shot you posted in the lamfa thread.  I pretty much copied it trying to figure out this lean condition.  I have also been messing with the table I mentioned in the first post.....adding on the higher load areas trying to.get more fuel, and pulling from the areas around 30-60% load to help with trims on the highway.

I didnt know the lc-1 could reset. I assumed since its still reading narrowband on putn outputs that its still set.  I do recalibrate it every time I pull the battery though.

It's a lc-1 emulating the two narrowband sensors.  I have a lm-1 that I can run too.  It's a bit nicer than the lc-1 setup since it isn't relying on system grounds to give me a actual reading.  Both of the lc-1 outputs are being used to satisfy the ecm.  I haven't used the lc-1 for logging yet.  Don't know how.  I just used it to eyeball afr. 

the filter option in ecuxplot....

youll want to log 3000 to redline, ideally

Did you read the FAQ? Did you configure your filter to match the gear you're logging? Why are you logging 2nd?


without knowing more about your MAF setup and/or the scaling you are using, or your KFMIRL, there's no way of saying. typically it doesn't matter much. you can run an underscaled maf just fine most of the time.

I left the LM-1 connected and watched the AFR on the highway today on my way to work.  THey stayed at 14.3-14.9 range.  I am going to call this good for now.  The voltage reading from my LM-1 are spot on for the AFR I was running, and this is what I expected from the LC-1.  I just dont understand how the ECU gets the right AFR if the o2 reorts something wacky.  Or maybe it isnt reporting wacky numbers, and I just dont understand what is going on. 

I also noticed that my LTFT didnt work.  They stayed all zero.  I am Ok with that, when the LTFT do actually kick in it usually splits my banks to where one bank is adding and the other bank is removing almoost the same amount.   I can actually feel it when the split goes over 10%, and as a result I have to keep my laptop in the passengers seat with VCDS open and reset the DTC's to clear out the LTFT.  This morning there was none of the crap, and it was actually quite nice having one less thing to worry about.
