You're getting the mechanics of it.  For dialing in purposes, you should disable the DFSO.  Even though you're filtering that out or think you are, you still have the lingering effects of it when it comes out of DFSO. It will skew the calculations.  Best save it's use for afterwards.

Just plot OL and look if it has two values.  Your earlier post with a data log, I don't recalling it being anything other that 1. 
1 is OL, 0 is not OL (CL).  The dashboard view while running/drive has always had it back wards by default.  Some have said it was fixed in recent BE releases but can't confirm.  And someone always brings it up now and then.
Your chart shows it too.  LAMBSE would be bouncing back and forth around 14.7, more or less depending on how close fuel was.  Your only variation is from different loads and follows the baseline fuel table.  Oh and mike's table number in his write-up is for cbaza, not gufx if you couldn't find it.

Filters. Not bad.  Can make TAR just 0 0.  I'd pick a higher ECT.  Default adaptives don't start till 170.  Not sure what he has in there.  That's the temp at where the KAMRF's start to update.  I use something like 195-205 or 210. Not much need to filter out maf.  Can leave PW out to if you redisable DFSO.  I'll filter out at times PW below say 2 or so.  That's usually the region of deceleration when they get that small.  Reason for, the smaller the PWs get, the more of an impact the injector offsets make.  And if you don't have good data on them, it helps to isolate that out.  You need to work that also too.  Those last three shown filters will have lingering affects too but not much can do about that and won't be that large. It does smooth out the results a good deal anyway.

My chart cause i'm closed loop looks very busy and they don't lay on top of each other but follow.  I use the serial input for my WB and there is some extra delay.  That's why the filters page has the WB Time Shift option.  But I don't bother.  I'll look more closely at the WOT portion of the chart.  That's where I expect my commanded say 12.5 to pretty much follow the AFR reading.  It's never perfect.  The start and stop portions seem to have some lag. But the rest will be within a point or two averaging out by eye some oscillation that appears.  Too many things going on for the actual AFR to ever be perfect and flat.

well it drove fine after changing the injector slopes and breakpoint. feeling ambitious, i adjusted the maf curve. it recommended a very minor change in the curve.

the only thing i didn't like with the recommended numbers was the MAF curve it recommended ended at 856 instead of 922... so i grafted the two together in excel. i have a 19lb BBK maf with "cold air calibration". there's no datasheet available for mine.  seems to run great.    

i was all excited to datalog on the ride home. i drove to the bank, came back to work and shut the car off. 2 minutes later when i restarted it wideband was being a POS.  i bought a new sensor, i'll look at it later.

That's where the stock curve end at a voltage just under 5V.  For all practical purposes, you're out of meter if you're at that point.  Time to get something bigger.

so.. the sensor i bought was a bosch 4.2, which it says would work, but the unit came with a more modern bosch 4.9.

i finally have a replacement 4.9 o2 now, but i see the failed one is very black and sooty. it's a very dry, wipes right off kinda soot.

i believe this is either because (all wild guesses, due to current lack of experience)

1- it runs way rich at cold start up with the A9L2, and it's been very cold out, requiring quite a while to warm up

2- my factory o2's may just be too old and sooty to be accurate anymore. maybe i should replace them? i hate buying stuff that isn't needed though.

3- i occasionally smell burnt oil after decelerating

4- by the time i felt smart enough to datalog and adjust the fuel and maf, perhaps the wideband sensor was already out of calibration, so my data was skewed? it failed only a few hours after the datalog i used to adjust the injectors/maf

i'm afraid to put the new sensor in, as i'm afraid it'll fry in short order.  
so now i'm a bit confused as how to proceed.

i could pick up a bosch 4.2 locally from autozone/orielly and just warranty it every week until i get it tuned better and then put the 4.9 back in... this would let me tune it(or maybe someone here knows how to get a 4.9 sensor locally?)

i did notice the A9L2 tune will make the motor fall on it's face for the first minute or so that i drive from a cold start. like it'll randomly cut out when i push the pedal more than a third but less than two thirds, and wants to bash my face into the steering wheel.

i read this a few times, but it says "if you're sure your fuel is dialed in" -which i am not.
http://efidynotuning.com/forum/viewtopic.php?f=7&t=738

how should i proceed?



i'm also (happily)slammed at work. been working 6am to 7pm and time to read/tune/tinker is at an all time low. i get home at 7:30, cook, eat, and go to bed at 9.

i think i'm getting it. the car runs well. i'm confused as EA keeps wanting me to raise my low slope and lower the high slope and breakpoint... latest it wants 16.75 and 27. currently I'm running it with 17.33 and 23.25.  should I keep doing what it tells me? dropping to 16.75 would richen it up and I believe it's already a bit richer than i'd like when i'm cruising and decelerating.

anyone care to grade my work?

edit: since i'm using a tweaked a9l2 tune and I like how it's running, I have enabled MFA mode. would this possibly be why it keeps telling me to go lower and higher on the slopes? like it's trying to correct for a non-existant condition?

Can't get the log to download here.  Can you zip it? Maybe to large.
The maf looks pretty normal.  Going by the values, guess it's 'cal'd' for stock 19s?
You left to top and bottom voltages in there - good.  Recommend that the 0v have the same value as the one above it.  But shouldn't cause anything as it.

So, without seeing the log it's hard to say if it's rich or not.  EA suggestion  is wanting to fatten up long injector widths, like at WOT, and lean out short widths like decel and low load conditions.  Injector offsets start becoming more of a significant impact at short widths.  If it thinks it's rich on the low slope, reducing offsets sometimes is required.  Are they stock injectors?  Verify that offset function is the same between the stock A9L and the A9L2.

Also, are you doing one change at a time?

If when you use the MAF tab/calculation, you need to reload your modified curve back into EA each time you've adjusted it for the next log/calculation.   Secondly, what it recommends and you put in into BE may not be same.  The cell values in BE only have so much resolution for a given parameter.  BE will automatically round up/down values to fit (cause it's a binary field).  So after you load them and run and log, export that curve back out to insert into EA before the new calculation.

wow! i had no idea the zip file would take it from 20mb down to 3.


yes the car has 19lb injectors

the MAF is a 76mm BBK with cold air calibration. when i contacted BBK about the MAF curve/transfer sheet, i was asking for more than they knew. i picked the stock foxbody MAF in EA and went from there.

to answer your question:
YES. i'm only doing one at a time (injectors) i believe i have the MAF more or less perfected so lately i just datalog the ride to work, analyze it, update my tune, clear my fuel trims, drive home, and then datalog the ride to work again the following morning. 
or if by "one at a time" you mean am i only changing the high or low slope each time, then no. i have been changing the high slope, low slope, and breakpoint each time.  since i'm getting better at this, i'm starting to wonder why it keeps telling me to make such drastic changes each time. i would expect it to only want me to adjust things .25 or so, but that is never the case.

See your KAMRF's are stuck at 1 in the log.   Bin shows, you disable adaptive control on purpose?  And looks like you changed idle adaptives too.  Unless his latest version has them set like that. 

You reenabled WOT mode spark control, but never repopulated the WOT spark function.  He has it zero'd out.  Did it have any power going at WOT??

Just some quick things that jump out.

I have the a9l2 with only injectors and maf adjusted.
 The idle he wrote I replaced with stock a9l stuff because the idle would hang.  I changed the idle to 680, and I enabled MFA. Other than that it's the stock a9l2 tune. What should I do to tweak the fuel correctly? I datalogged the ride home and I'll datalog the ride to work.

If it helps I can use the stock tune with my maf and post that.  Once I get the fuel injectors dialed I think I'll have learned the basics.

I have plenty of power. I've been smoking Audis and Camaros all day. WOT is great. The car's fun sand wild to drive. I've never touched any spark tables

Hmm... you're right.  Just downloaded his latest.  Odd that he has

AFACT1   Fuel - Adaptive Control ACT Minimum set to 258 which effectively disables.  The older version had it at 20 degrees. 

And
Z_WSPKSW   Spark - WOT Mode Spark Control Enable/Disable is enabled.  Which uses the normal function like stock.

This is how it shows up when I open his file.  Is it same for you?

AFACT1 says 258 on mine.

I cannot see "Z_WSPKSW   Spark - WOT Mode Spark Control" -I deleted the scalar from my xls definition file because I had an error popping up. when I googled it, I found this: http://www.efidynotuning.com/forum/viewtopic.php?f=7&t=1545#p17906

they WERE updating. ill look at it. I had a bad upload a couple days ago. maybe when I cleared them and then re-uploaded the tune it's still stuck on clear (meaning Z_KAMCLR)

in the datalog from Feb 21, KAMRF's had actual values.

i'll re-upload the tune to my QH, and post a new datalog tomorrow.

Yeah, even though the tuning isn't really hard, the is a bit of ATD, attention to details, in the process.  Until you get that automatic groove, things like 'unsetting the kamclr' can bite you. lol  I thought that yesterday til i saw the 258.  Decipha said it's fine and a def file thing.

it seems to be working again. this datalog is about 30 minutes, maybe 15 spent idling. then I filtered it using the filters you told me to use previously. I drove around installing some signs at a couple carwashes and let it run while I worked.

now it wants me to change the high slope to 16.xx, the low to 32, and the BP to 2.05

should I give it what it wants and see what happens?
should I possibly replace the o2's? they might be 23 years old.

I renamed my tune to something "easier to notice" Grin. I think at some point even I mixed up A9L2 and my A9LR.
